Abstract
Brucella species are facultative intracellular bacterial pathogens that cause the contagious zoonotic disease, brucellosis. Brucella spp. infect a wide range of animals, including livestock, wild animals, and marine mammals. Compared with other invasive bacterial pathogens, partial information is available on the virulence factors of Brucella that enable them to survive in the host. Here, we performed transposon-based random mutagenesis of B. neotomae and identified the arginine/ornithine binding protein, ArgT, as one of the crucial virulence determinants of Brucella. Deleting ArgT from B. neotomae or B. melitensis resulted in its attenuation in macrophages, which was restored upon complementation with an ArgT expression plasmid. We observed that macrophages infected with ΔArgT-B. neotomae produced elevated levels of NO due to the inability of these mutants to deplete the host intracellular arginine through their importer. Furthermore, defective survival of ΔArgT B. neotomae and B. melitensis was observed in the infected mice, which correlated with enhanced NO production in the mice. Our studies revealed that ArgT plays a vital role in preventing intracellular killing and contributes to the chronic persistence of B. neotomae/B. melitensis in the host. This study highlights the essential role of arginine in clearing intracellular infections and the subversion of this host defense mechanism by intracellular pathogens for their chronic persistence.

Abstract
OBJECTIVES To investigate associations of the carriage of single nucleotide polymorphisms (SNPs) of proteins involved in the immune response of patients with brucellosis. METHODS A case control study of patients with brucellosis upon WHO criteria. Blood genomic analysis was performed by RFLP- PCR for the detection of SNPs: i) at promoters -376 G > A (rs1800750); -308 G > A (rs 1,800,629); -238 G > A (rs361525) of the TNF gene, ii) at -896 A > G Asp299Gly (rs4986790) and -1196 C > T Thr399Ile (rs4986791) positions of the TLR-4 gene. Logistic regression analysis of factors related to brucellar spondylodiscitis was performed. RESULTS Patients with brucellosis (n = 105) were male (n = 67, 63.8 %); mean age (SD): 49.51(18.31); spondylodiscitis (n = 30), sacral osteomyelitis (n = 21). Carriage of the minor frequency A alleles at -238 of the promoter region of TNF was greater in patients than in controls (11.4% vs 2.6 %, p < 0.001). In a stepwise regression model including host variables and TNF-238 G A-1 genotype, only the last one was associated with brucellar spondylodiscitis [OR 2.91 (CI95 % 1.02-8.31), p = 0.047]. CONCLUSIONS In our cohort, the association of one TNF SNP of patients with brucellosis, in particular spondylodiscitis, might be prognostic whereas further investigation of the exact role in the host immune response is required.

Abstract
Brucellosis is a zoonotic infection caused by the Brucella species of bacteria. It is mainly transmitted to humans through consuming unpasteurized dairy products or through direct contact with infected animals. Brucellosis can present with a variety of symptoms, including fever, fatigue, weight loss, and organ-specific complications. Treatment typically includes a short course of an aminoglycoside with a longer course of a tetracycline. In this case report, we present a 50-year-old Hispanic male who developed brucellosis after consuming large quantities of unpasteurized goat's milk while tending to goats and horses. The patient originally presented with fever, dyspnea, and headache. Initially treated with doxycycline and gentamicin, he presented two months later with testicular pain and swelling and was found to have epididymo-orchitis secondary to brucellosis. This rare complication is only present in a few percent of cases. The patient was treated for focal infection with a combination of doxycycline, rifampin, and amikacin with a favorable response to therapy.

Abstract
Brucella ovis is an etiologic agent of ovine epididymitis and brucellosis that causes global devastation in sheep, rams, goats, small ruminants and deer. There are no cost-effective methods for the worldwide eradication of ovine brucellosis. B. ovis and other protein targets from various Brucella species are currently in the pipeline for high-throughput structural analysis at the Seattle Structural Genomics Center for Infectious Disease (SSGCID), with the aim of identifying new therapeutic targets. Furthermore, the wealth of structures generated are effective tools for teaching scientific communication, structural science and biochemistry. One of these structures, B. ovis leucine-, isoleucine-, valine-, threonine- and alanine-binding protein (BoLBP), is a putative periplasmic amino acid-binding protein. BoLBP shares less than 29% sequence identity with any other structure in the Protein Data Bank. The production, crystallization and high-resolution structures of BoLBP are reported. BoLBP is a prototypical bacterial periplasmic amino acid-binding protein with the characteristic Venus flytrap topology of two globular domains encapsulating a large central cavity containing the peptide-binding region. The central cavity contains small molecules usurped from the crystallization milieu. The reported structures reveal the conformational flexibility of the central cavity in the absence of bound peptides. The structural similarity to other LBPs can be exploited to accelerate drug repurposing.

Abstract
Brucellosis is a difficult to treat infection that requires antibiotic combinations administered over several weeks for clearance of infection and relapse prevention. This systematic review summarizes current evidence for antibiotic treatment of human brucellosis. PubMed, EMBASE, Scopus, CINAHL, Web of Science, and China Academic Journal databases were searched for prospective studies that had compared different antibiotic regimens for treating human brucellosis in the last 25 years. Thirty-four studies recruiting 4182 participants were eligible. Standard dual therapy with doxycycline + rifampicin had a higher risk of treatment failure compared to triple therapy which added streptomycin (RR: 1.98, 95% CI 1.17-3.35, p = 0.01) or levofloxacin (RR: 2.98, 95% CI 1.67-5.32, p = 0.0002), but a similar or lower risk compared to alternative dual antibiotic combinations (p > 0.05). The same combination had a higher risk of relapses compared to triple therapy which added streptomycin (RR: 22.12, 95% CI 3.48-140.52, p = 0.001), or levofloxacin (RR: 4.61, 95% CI 2.20-9.66, p < 0.0001), but a similar or lower risk compared to other dual antibiotic combinations (p > 0.05). Triple antibiotic therapy is more effective than standard dual therapy with rifampicin and doxycycline. However, the latter is also efficacious and suitable for uncomplicated disease.

Abstract
BACKGROUND In clinical practice guidelines, there is no consensus about the medications that should be initially offered to patients with brucellosis. To provide informative evidence, we compared and ranked brucellosis medications based on their efficacy and safety. METHODS For this systematic review and network meta-analysis, we searched 4 English databases and 3 Chinese databases, from the date of database inception to December 13, 2023. We included randomized controlled trials (RCTs) involving children and adolescents with brucellosis, comparing different antibiotic regimens. We excluded studies explicitly targeting patients with spondylitis brucellosis, endocarditis brucellosis, and neuro-brucellosis. The primary outcomes were overall failure (efficacy) and side effects (safety). Secondary outcomes were relapse and therapeutic failure. Pairwise meta-analysis was first examined. Data were analyzed using random effects network meta-analysis, with subgroup and sensitivity analyses performed. The Confidence in Network Meta-Analysis (CINeMA) framework was used to assess the certainty of evidence. The protocol was preregistered in PROSPERO (CRD42023491331). RESULTS Of the 11,747 records identified through the database search, 43 RCTs were included in the network meta-analysis. Compared with standard therapy (Doxycycline + Rifampicin), Rifampicin + Tetracyclines (RR 4.96; 95% CI 1.47 to 16.70; very low certainty of evidence), Doxycycline + TMP/SMX (RR 0.18; 95% CI 0.06 to 0.52; low certainty of evidence), Doxycycline + Quinolones (RR 0.27; 95% CI 0.11 to 0.71; low certainty of evidence), Streptomycin + Tetracyclines (RR 0.04; 95% CI 0.01 to 0.16; low certainty of evidence), and Single (RR 0.05; 95% CI 0.02 to 0.16; moderate certainty of evidence) were less efficacious. Doxycycline + Gentamicin ranked the best in efficacy (SUCRA values: 0.94), the second is Triple (SUCRA values: 0.87), and the third is Doxycycline + Streptomycin (SUCRA values: 0.78). CONCLUSIONS Brucellosis medications differ in efficacy and safety. Doxycycline + Gentamicin, Triple, and Doxycycline + Streptomycin have superior efficacy and safety. Treatment of brucellosis should strike a balance between efficacy, safety, and cost.

Abstract
Brucellosis is a serious public health problem worldwide and can affect any organ system. Due to brucellosis's variable clinical presentation, ranging from subclinical to fully symptomatic, and limited available information, it poses a diagnostic challenge. In this study, we reported a case series of patients with diverse presentations. In addition, we briefly described the pathophysiology and mechanisms of Brucella in the body. These case presentations will be valuable in increasing the awareness of physicians. A prompt diagnosis is crucial, as detecting some clues of the infection in its early stages can help avoid misdiagnoses.

Abstract
Brucellosis is an infection widely distributed around the world, and in some countries it is considered a public health problem. Brucellosis causes insidious symptoms that make it difficult to diagnose. Infection can also trigger chronic pain and neuropsychiatric complications. Antibiotics are not always effective to eradicate infection, contributing to chronicity. We aimed to investigate the effects of antibiotic treatment on proinflammatory cytokines, neurotransmitters, corticosterone, and behavior in a murine model of infecrion of B. abortus strain 2308. Four study groups were created: (a) control; (b) antibiotic control; (c) infected with B. abortus 2308; and (d) infected and treated with rifampicin and doxycycline. We determined B. abortus 2308 colony-forming units (CFUs), the count of dendritic cells, and macrophages in the spleen; serum levels of cytokines and corticosterone; levels of serotonin, dopamine, epinephrine, and norepinephrine in the brain; and equilibrium, physical strength, anxiety, and hopelessness tests. The infected and treated mice group was compared with the control and infected mice to assess whether treatment is sufficient to recover neuroimmunoendocrine parameters. Our results showed that despite the treatment of brucellosis with rifampicin and doxycycline, antibiotic-treated mice showed a persistence of B. abortus 2308 CFUs, an increased count in macrophage number, and higher circulating levels of corticosterone. Furthermore, the levels of IL-12, IL-6, and TNF-α remained higher. We found a decrease in muscular strength and equilibrium concomitant to changes in neurotransmitters in the hippocampus, cerebellum, and frontal cortex. Our data suggest that the remaining bacterial load after antibiotic administration favors inflammatory, neurochemical, and behavioral alterations, partly explaining the widespread and paradoxical symptomatology experienced by patients with chronic brucellosis.

Abstract
One zoonotic infectious animal disease is brucellosis. The bacteria that cause brucellosis belong to the genus Brucella. Numerous animal and human species are affected by brucellosis, with an estimated 500,000 human cases recorded annually worldwide. The occurrence of new areas of infection and the resurgence of infection in already infected areas indicate how dynamically brucellosis is distributed throughout different geographic regions. Bacteria originate from the blood and are found in the reticuloendothelial system, the liver, the spleen, and numerous other locations, including the joints, kidneys, heart, and genital tract. Diagnosis of this disease can be done by bacterial isolation, molecular tests, modified acid-fast stain, rose bengal test (RBT), milk ring test, complement fixation test, enzyme-linked immunosorbent assay, and serum agglutination test. The primary sign of a Brucella abortus infection is infertility, which can result in abortion and the birth of a frail fetus that may go on to infect other animals. In humans, the main symptoms are acute febrile illness, with or without localization signs, and chronic infection. Female cattle have a greater risk of contracting Brucella disease. Human populations at high risk of contracting brucellosis include those who care for cattle, veterinarians, slaughterhouse employees, and butchers. Antibiotic treatment of brucellosis is often unsuccessful due to the intracellular survival of Brucella and its adaptability in macrophages. A "one health" strategy is necessary to control illnesses like brucellosis.

Abstract
This study aimed to assess the clinical characteristics, treatment, and prognosis of osteoarticular brucellosis. We conducted a retrospective study enrolling brucellosis patients from the Sixth People's Hospital of Shenyang between September 2014 and June 2019. A total of 1917 participants were admitted during this period. After applying propensity score matching, we retrospectively analyzed 429 patients with osteoarthritis and 429 patients without osteoarthritis. The primary outcome was treatment completion. The secondary outcome was symptom disappearance and seroconversion. Brucellosis patients with osteoarthritis had longer treatment course (160 [134.3-185.7] vs. 120 [102.3-137.7] d, p = 0.008) than those without osteoarthritis. The most common involved site was lumbar vertebrae (290 [67.6%]) in brucellosis patients with osteoarthritis. Longer symptom duration (90 [83.0-97.0] vs. 42 [40.2-43.8], p < 0.001) along with no significant difference in seroconversion (180 [178.8-181.2] vs. 180 [135.1-224.9], p = 0.212) was observed in osteoarthritis patients with treatment course >90 d. Peripheral joint involvement (adjusted hazard ratio [95% confidence interval] 1.485 [1.103-1.999]; p = 0.009) had a shorter symptom duration compared with shaft joint involvement. No significant differences were observed in treatment therapy between doxycycline plus rifampin (DR) or plus cephalosporins (DRC) in treatment course (p = 0.190), symptom persistence (p = 0.294), and seroconversion (p = 0.086). Lumbar vertebra was the most commonly involved site. Even if all symptoms disappeared, Serum agglutination test potentially remained positive in some patients. Compared with peripheral arthritis, shaft arthritis was the high-risk factor for longer symptom duration. The therapeutic effects were similar between DR and DRC. In summary, our study provided important insights into the clinical characteristics, treatment, and outcomes of osteoarticular brucellosis. Clinical Trial Registration number: NCT04020536.

Abstract
RATIONALE Rifampicin, as a main chemotherapy drug treating brucellosis, is widely used in clinical practice. Rifampicin-associated ARF is not rare, especially in those rifampicin re-exposure patients. However, this was rare complication of severe renal involvement due to multiple factors including rifampicin, nephrotoxic gentamicin, and contrast medium, and few studies have reported it. PATIENT CONCERNS A 59-year-old male presented to our hospital with acute renal failure (ARF) caused by anti-brucellosis treatment with rifampicin (675 mg/day), gentamicin (320 mg/day), and doxycycline (200 mg/day). He had a contrast-enhanced CT of the upper abdomen before the onset of. After stopping rifampicin and undergoing integrated therapy, the patient's renal function gradually recovered. DIAGNOSES Considering that the patient had a history of using rifampicin for pulmonary tuberculosis in the past, based on the examination results, the patient was diagnosed with rifampicin-associated ARF. INTERVENTIONS Symptomatic treatment such as hemodialysis, and anti-brucella treatment with doxycycline and moxifloxacin were given. OUTCOMES The patient had significant anuric and polyuric periods and acute tubular necrosis is considered. After treatment, his renal function and urine volume returned to normal, and Brucella melitensis was not isolated from blood cultures. LESSONS The case reveals that severe renal involvement due to multiple factors including rifampicin, nephrotoxic gentamicin, and contrast medium. Misdiagnosis and mistreatment can deteriorate the patient's condition. Renal function should be closely monitored in the susceptible patients. Early recognition can provide appropriate therapy to patients. If unexplained renal failure during the use of rifampicin, especially in those rifampicin re-exposure patients, rifampicin-associated ARF should be considered.

Abstract
The most prevalent zoonotic disease is brucellosis, which poses a significant threat for worldwide public health. Particularly in endemic areas, spinal involvement is a major source of morbidity and mortality and can complicate the course of the disease. The diagnosis of Brucella spondylitis is challenging and should be suspected in the appropriate epidemiological and clinical context, in correlation with microbiological and radiological findings. Treatment depends largely on the affected parts of the body. Available treatment options include antibiotic administration for an adequate period of time and, when appropriate, surgical intervention. In this article, we examined the most recent data on the pathophysiology, clinical manifestation, diagnosis, and management of spinal brucellosis in adults.

Abstract
Background: Brucellosis is a pervasive zoonotic disease caused by various Brucella species. It mainly affects livestock and wildlife and poses significant public health threats, especially in regions with suboptimal hygiene, food safety, and veterinary care standards. Human contractions occur by consuming contaminated animal products or interacting with infected animals. Objective: This study aims to provide an updated understanding of brucellosis, from its epidemiology and pathogenesis to diagnosis and treatment strategies. It emphasizes the importance of ongoing research, knowledge exchange, and interdisciplinary collaboration for effective disease control and prevention, highlighting its global health implications. Methods: Pathogenesis involves intricate interactions between bacteria and the host immune system, resulting in chronic infections characterized by diverse clinical manifestations. The diagnostic process is arduous owing to non-specific symptomatology and sampling challenges, necessitating a fusion of clinical and laboratory evaluations, including blood cultures, serological assays, and molecular methods. Management typically entails multiple antibiotics, although the rise in antibiotic-resistant Brucella strains poses a problem. Animal vaccination is a potential strategy to curb the spread of infection, particularly within livestock populations. Results: The study provides insights into the complex pathogenesis of brucellosis, the challenges in its diagnosis, and the management strategies involving antibiotic therapy and animal vaccination. It also highlights the emerging issue of antibiotic-resistant Brucella strains. Conclusions: In conclusion, brucellosis is a significant zoonotic disease with implications for public health. Efforts should be directed towards improved diagnostic methods, antibiotic stewardship to combat antibiotic resistance, and developing and implementing effective animal vaccination programs. Interdisciplinary collaboration and ongoing research are crucial for addressing the global health implications of brucellosis.

Abstract
MALDI-TOF mass spectrometry (MS) has proven to be a fast and reliable method for the identification of a large number of taxonomic groups. It offers the advantage of being able to incorporate protein spectra of microorganisms that are absent or poorly represented in commercial databases, such as the genus Brucella. The aim of the study was to build the first database of protein spectra of local biological variants of Brucella in Argentina and of standard strains. First, the identification performance of a panel of 135 strains was evaluated with the Swedish database ¨Folkhälsomyndigheten¨ (containing protein spectra of several international standards of the genus Brucella) imported from the open access site https://spectra.folkhalsomyndigheten.se/spectra/. With this library 100 % of the strains were correctly identified by mass spectrometry to genus level, but not to species level. Due to the limitation found, an in-house database was designed with local Brucella isolates from Argentina and standard strains used in routine bacteriological diagnosis. For its validation, a panel of strains, different from those used to develop the extended local database (n: 177), was used to, simultaneously, challenge both libraries. The samples were processed by triplicate and the results obtained were: 177 strains correctly identified to genus and species level compared to the gold standard method (phenotypic typing), meeting the criteria accepted by the literature and the manufacturer as reliable identification. Only 2 of these isolates had score values lower than 2 (1.862) and were therefore not included in the calculation of results. According to these results, MALDI-TOF MS is a fast and reliable method for the routine identification of the different Brucella species, and even has the advantage of reducing the time of exposure to pathogenic microorganisms for laboratorians. It could be considered a valuable technique to replace, in the near future, the current conventional techniques due to the ease of transferring protein spectra, avoiding the use of reference strains that are difficult to find commercially available and commonly used in phenotypic typing.

Abstract
Key Clinical Message Brucella aortitis should be one of the differential diagnoses of inflammatory aortic aneurysms. In situ repair of intermittent aortoenteric fitulae and repair of infrarenal aortic aneurysm with synthetic graft can be used in clean scarred fistulae. Abstract Arterial aneurysms are very rare complications of Brucella infection. The purpose of this case report is to document a case of abdominal aortic aneurysm and primary aorto-duodenal fistula as a complication of Brucella infection, along with the management of brucella induced aortoenteric fistula with insitu synthetic graft. We report a 53-year-old man with a complaint of abdominal pain and melena. Radiological evaluation revealed an inflammatory abdominal aortic aneurysm and a primary aorto-duodenal fistula was identified during surgery. The patient underwent laparotomy, and surgical repair of the aneurysm with a bifurcated Dacron graft, while the entry of the aorto-duodenal fistula was closed with intra-aortic sutures. One month later, the patient tested positive for the Wright agglutination test (1:80) and Coomb's test (1:640) for brucella, and was treated with doxycycline, rifampicin, and ciprofloxacin for brucellosis. Though rare, brucella aortitis should be considered as one of the differential diagnoses of inflammatory aortic aneurysms. In situ repair of intermittent aortoenteric fistula and repair of the infrarenal aortic aneurysm with synthetic graft could be considered in a clean scarred fistula.

Abstract
BACKGROUND Brucellosis, a common zoonotic disease worldwide, can lead to serious complications in humans. In Oman, the disease occurs most often in the south, but is increasing in the north. OBJECTIVES Describe brucellosis in children in the Northern Governorate in Oman. DESIGN Retrospective, observational. SETTINGS Hospitals in the Northern Governorate in Oman. PATIENTS AND METHODS We collected data on the demographics, distribution, common clinical presentations, risk factors, laboratory findings, therapy, and complications of confirmed cases of brucellosis. We included all brucellosis cases up to the age of 13 years at the Child Health Department in Royal, Suhar, Al Rustaq and Nizwa Hospitals over a 15-year period. MAIN OUTCOME MEASURES Descriptive findings of brucellosis. SAMPLE SIZE 57 confirmed cases. RESULTS The 57 confirmed cases of Brucella had a mean age of 6 years. Most of the cases were from Dhakhiliya 21 (36.8%) and Batinah 18 (31.6%). Consumption of raw milk was documented in 75% and 41% had animal contact. From 2010, there was a marked rise of the cases with a maximum rise was noticed in 2019 with a total of 10 cases. The main clinical manifestations were fever (92%, n=52), arthritis (44%, n=25), which involved mainly knees and hips. Forty-two had bacteremia, 41% anemia, 10% osteomyelitis/septic arthritis, one case with congenital brucellosis and one case neurobrucellosis (1.8%). Forty cases had positive serology results of which 19 had positive cultures. Most cases had received cotrimoxazole and rifampin as the primary treatment regimen 22 (40%). Four patients relapsed (7%) after treatment completion. CONCLUSION This study showed the distribution and clinical characteristics of brucellosis in different regions in the Northern Governorate in Oman. Although the numbers of cases remained low, the gradual increase is concerning for public health and preventive strategies. Further studies are needed to compare this data with the Southern region. LIMITATION Retrospective study with small sample size.

Abstract
Brucellosis infection causes non-specific symptoms such as fever, chills, sweating, headaches, myalgia, arthralgia, anorexia, fatigue, and mood disorders. In mouse models, it has been associated with increased levels of IL-6, TNF-α, and IFN-γ, a decrease in serotonin and dopamine levels within the hippocampus, induced loss of muscle strength and equilibrium, and increased anxiety and hopelessness. Imipramine (ImiP), a tricyclic antidepressant, is used to alleviate neuropathic pain. This study evaluated the effects of ImiP on Balb/c mice infected with Brucella abortus 2308 (Ba) at 14- and 28-days post-infection. Serum levels of six cytokines (IFN-γ, IL-6, TNF-α, IL-12, MCP-1. and IL-10) were assessed by FACS, while the number of bacteria in the spleen was measured via CFU. Serotonin levels in the hippocampus were analyzed via HPLC, and behavioral tests were conducted to assess strength, equilibrium, and mood. Our results showed that mice infected with Brucella abortus 2308 and treated with ImiP for six days (Im6Ba14) had significantly different outcomes compared to infected mice (Ba14) at day 14 post-infection. The mood was enhanced in the forced swimming test (FST) (p < 0.01), tail suspension test (TST) (p < 0.0001), and open-field test (p < 0.0001). Additionally, there was an increase in serotonin levels in the hippocampus (p < 0.001). Furthermore, there was an improvement in equilibrium (p < 0.0001) and muscle strength (p < 0.01). Lastly, there was a decrease in IL-6 levels (p < 0.05) and CFU count in the spleen (p < 0.0001). At 28 days, infected mice that received ImiP for 20 days (Im20Ba28) showed preservation of positive effects compared to infected mice (Ba28). These effects include the following: (1) improved FST (p < 0.0001) and TST (p < 0.0001); (2) better equilibrium (p < 0.0001) and muscle strength (p < 0.0001); (3) decreased IL-6 levels (p < 0.05); and (4) reduced CFU count in the spleen (p < 0.0001). These findings suggest the potential for ImiP to be used as an adjuvant treatment for the symptoms of brucellosis, which requires future studies.

Blasco JM, Moreno E, Muñoz PM, Conde-Álvarez R, Moriyón I. A review of three decades of use of the cattle brucellosis rough vaccine Brucella abortus RB51: myths and facts. BMC Vet Res 2023; 19:211. [PMID: 37853407 PMCID: PMC10583465 DOI: 10.1186/s12917-023-03773-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 10/04/2023] [Indexed: 10/20/2023] Open
Abstract
Cattle brucellosis is a severe zoonosis of worldwide distribution caused by Brucella abortus and B. melitensis. In some countries with appropriate infrastructure, animal tagging and movement control, eradication was possible through efficient diagnosis and vaccination with B. abortus S19, usually combined with test-and-slaughter (T/S). Although S19 elicits anti-smooth lipopolysaccharide antibodies that may interfere in the differentiation of infected and vaccinated animals (DIVA), this issue is minimized using appropriate S19 vaccination protocols and irrelevant when high-prevalence makes mass vaccination necessary or when eradication requisites are not met. However, S19 has been broadly replaced by vaccine RB51 (a rifampin-resistant rough mutant) as it is widely accepted that is DIVA, safe and as protective as S19. These RB51 properties are critically reviewed here using the evidence accumulated in the last 35 years. Controlled experiments and field evidence shows that RB51 interferes in immunosorbent assays (iELISA, cELISA and others) and in complement fixation, issues accentuated by revaccinating animals previously immunized with RB51 or S19. Moreover, contacts with virulent brucellae elicit anti-smooth lipopolysaccharide antibodies in RB51 vaccinated animals. Thus, accepting that RB51 is truly DIVA results in extended diagnostic confusions and, when combined with T/S, unnecessary over-culling. Studies supporting the safety of RB51 are flawed and, on the contrary, there is solid evidence that RB51 is excreted in milk and abortifacient in pregnant animals, thus being released in abortions and vaginal fluids. These problems are accentuated by the RB51 virulence in humans, lack diagnostic serological tests detecting these infections and RB51 rifampicin resistance. In controlled experiments, protection by RB51 compares unfavorably with S19 and lasts less than four years with no evidence that RB51-revaccination bolsters immunity, and field studies reporting its usefulness are flawed. There is no evidence that RB51 protects cattle against B. melitensis, infection common when raised together with small ruminants. Finally, data acumulated during cattle brucellosis eradication in Spain shows that S19-T/S is far more efficacious than RB51-T/S, which does not differ from T/S alone. We conclude that the assumption that RB51 is DIVA, safe, and efficaceous results from the uncritical repetition of imperfectly examined evidence, and advise against its use.

Effect of awareness training to frontline health workers and the use of e-based technology on reporting of brucellosis cases in selected pastoral communities, Tanzania: a quasi-experimental study. ONE HEALTH OUTLOOK 2023; 5:13. [PMID: 37817289 PMCID: PMC10566055 DOI: 10.1186/s42522-023-00084-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 06/15/2023] [Indexed: 10/12/2023]
Abstract
INTRODUCTION Brucellosis is a serious community health problem and endemic disease in Tanzania in both humans and animals. Frontline health workers (FHWs) play a vital role in reporting and hence prevent and control brucellosis in rural settings. This study aims to evaluate the effect of awareness training to frontline health workers and use of electronic technology (e- technology) on reporting of brucellosis cases. METHODS A quasi-experimental design was implemented in two pastoral communities in eastern part of Tanzania with one as control and another as treatment involving 64 FHWs who were purposively selected from May 2020 to December 2020. A total of 32 FHWs from treatment pastoral community were purposively selected for awareness training, rapid diagnosis using Rose Bengal test (RBT) and use of electronic technology (AfyaData app) for brucellosis reporting while nothing was done in control community. Before and after training information about their knowledge, attitude and practices were collected from all participants using a structured questionnaires uploaded in the mobile phone powered by AfyaData application. Blood samples were collected from 141 febrile patients attending the selected facilities in treatment community. Serum obtained from collected blood were analyzed using RBT and Competitive Enzyme Linked Immunosorbent Assay (c-ELISA) for brucellosis screening and confirmatory, respectively. Results from this analysis were reported back to the health facility using AfyaData app. Chi-square was used to analyze categorical variables and t-test and/Anova test was used to assess the effectiveness of the intervention. RESULTS Results revealed that before the training majority of the participants were ignorant about brucellosis, although they had good attitude towards brucellosis prevention. Participant's awareness, practice and attitude increased significantly (p = 0.003, p = 0.001, p = 0.032) respectively, after the intervention. Total of 17(12.1%) patients were positive on RBT and four (2.8%) were confirmed by c-ELISA. AfyaData app was proven to provide quick reports regarding brucellosis in the study area. CONCLUSION The training program was effective in increasing the level of knowledge and practice about brucellosis. Electronic based technology (AfyaData app) improved the reporting of brucellosis cases. There is a need for the use of electronic based technology to improve timely management of brucellosis in pastoral communities. Also, continuous training on FHWs regarding the disease is needed to improved their awareness and practices.

Immuno-profiling of Brucella proteins for developing improved vaccines and DIVA capable serodiagnostic assays for brucellosis. Front Microbiol 2023; 14:1253349.

Abstract
Brucellosis remains a worldwide zoonotic disease with a serious impact on public health and livestock productivity. Controlling brucellosis in livestock is crucial for limiting human infections in the absence of effective human vaccines. Brucellosis control measures are majorly dependent on rigorous monitoring of disease outbreaks and mass vaccination of livestock. Live attenuated vaccines are available for livestock vaccination that play a vital role in brucellosis control programs in many countries. Even though the existing animal vaccines confer protection against brucellosis, they carry some drawbacks, including their infectivity to humans and interference with sero-monitoring. The available serodiagnostic assays for brucellosis depend on detecting anti-LPS antibodies in the serum. Since diagnosis plays a vital role in controlling brucellosis, developing improved serodiagnostic assays with enhanced specificity, sensitivity and DIVA capability is required. Therefore, it is essential to identify novel antigens for developing improved vaccines and serodiagnostic assays for brucellosis. In the present study, we performed a high throughput immunoprofiling of B. melitensis protein microarray using brucellosis-positive human and animal serum samples. The screening identified several serodominant proteins of Brucella that exhibited common or differential reactivity with sera from animals and humans. Subsequently, we cloned, expressed, and purified ten serodominant proteins, followed by analyzing their potential to develop next-generation vaccines and improved serodiagnostic assays for brucellosis. Further, we demonstrated the protective efficacy of one of the serodominant proteins against the B. melitensis challenge in mice. We found that the seroreactive protein, Dps (BMEI1980), strongly reacted with brucellosis-positive serum samples, but it did not react with sera from B. abortus S19-vaccinated cattle, indicating DIVA capability. A prototype lateral flow assay and indirect ELISA based on Dps protein exhibited high sensitivity, specificity, and DIVA capability. Thus, the present study identified promising candidates for developing improved vaccines and affordable, DIVA-capable serodiagnostic assays for animal and human brucellosis.

Abstract
BACKGROUND The treatment of brucellosis suffers from a high recurrence rate and drug resistance. Our study researched the differences in efficacy and side effects between triple antibiotics therapy and dual antibiotics therapy in the treatment of brucellosis through a systematic review and meta-analysis. METHODS We searched 4 English electronic databases and 2 Chinese electronic databases for randomized controlled trials and cohort studies published through September 2022 on the use of triple antibiotics versus dual antibiotics in the treatment of brucellosis. Overall outcome indicators were therapeutic failure rate, relapse rate, overall therapeutic failure rate, and side effect rate. Relative risk (RR) and 95% confidence intervals (95% CIs) were used as summary statistics. A fixed-effects model was used to combine the overall effect sizes. RESULTS The meta-analysis included 15 studies consisting of 11 randomized controlled trials and 4 cohort studies. Triple antibiotics showed better efficacy than dual antibiotics in a comparison of 3 overall outcome indicators (therapeutic failure rate (RR 0.42; 95% CI 0.30 to 0.59 heterogeneity P = 0.29, I2 = 15%), relapse rate (RR 0.29; 95% CI 0.18 to 0.45 heterogeneity P = 0.88, I2 = 0%), and overall therapeutic failure rate (RR 0.37; 95% CI 0.28 to 0.48 heterogeneity P = 0.35, I2 = 9%)). The incidence of side effects in patients with brucellosis treated with triple antibiotics was not significantly different from that in brucellosis patients treated with dual antibiotics (RR 0.85; 95% CI 0.67 to 1.06 heterogeneity P = 0.1, I2 = 35%). Sensitivity analyses showed robust results and Peter's test showed no publication bias. The results of subgroup analyses for the research type, drugs, and type of brucellosis were largely consistent with the overall outcome indicators, indicating the reliability and robustness of the overall results. CONCLUSIONS In the treatment of brucellosis, triple antibiotics have better efficacy than dual antibiotics and do not increase the incidence of side effects.

Abstract
Brucellosis is a common zoonosis, which is caused by Brucella infection, and Brucella often infects livestock, leading to abortion and infertility. At present, human brucellosis remains one of the major public health problems in China. According to previous research, most areas in northwest China, including Xinjiang, Tibet, and other regions, are severely affected by Brucella. Although there are vaccines against animal Brucellosis, the effect is often poor. In addition, there is no corresponding vaccine for human Brucellosis infection. Therefore, a new strategy for early prevention and treatment of Brucella is needed. A multi-epitope vaccine should be developed. In this study, we identified the antigenic epitopes of the Brucella type IV secretion system VirB8 and Virb10 using an immunoinformatics approach, and screened out 2 cytotoxic T lymphocyte (CTL) epitopes, 9 helper T lymphocyte (HTL) epitopes, 6 linear B cell epitopes, and 6 conformational B cell epitopes. These advantageous epitopes are spliced together through different linkers to construct a multi-epitope vaccine. The silico tests showed that the multi-epitope vaccine was non-allergenic and had a strong interaction with TLR4 molecular docking. In immune simulation results, the vaccine construct may be useful in helping brucellosis patients to initiate cellular and humoral immunity. Overall, our findings indicated that the multi-epitope vaccine construct has a high-quality structure and suitable characteristics, which may provide a theoretical basis for the development of a Brucella vaccine.

Abstract
Brucellosis is a common zoonotic infectious disease with diverse and non-specific clinical manifestations caused by Brucella. Although Brucella can cause damage to multiple systems in the human body, hematological complications are relatively rare. We present a case of a 47-year-old male brucellosis patient with pancytopenia. In May 2018, the patient was diagnosed with brucellosis and recovered after receiving antibiotic treatment (rifampicin 600 mg/day and doxycycline 200 mg/day) for six weeks. However, after three years, the patient experienced a recurring high fever. Brucellosis relapse was confirmed based on the patient's clinical history, Rose Bengal plate agglutination test and standard tube agglutination test results. Routine blood examination revealed a decrease in the whole blood cell count, suggesting bone marrow suppression. Bone marrow aspiration and bacterial culture confirmed the diagnosis of brucellosis with pancytopenia. Antibiotic treatment failed to effectively improve the patient's condition. Therefore, a combination of immunomodulatory and antibiotic treatments was used. The antibiotic regimen included oral rifampicin 600 mg/day, intravenous doxycycline hydrochloride 200 mg/day, and subcutaneous injection of human granulocyte-stimulating factor (0.2 mg/day). Immunomodulatory therapy consisted of 20,000 mg/day intravenous human immunoglobulin (pH 4) for five days and 800 mg/day oral pidotimod liquid for 20 days. As the treatment progressed, the count gradually recovered to normal levels, and the symptoms of bone marrow suppression were alleviated. PCR testing revealed the absence of Brucella DNA in both monocyte and serum samples. Furthermore, negative standard tube agglutination test results were obtained. These findings indicate that the immunomodulatory therapy resulted in a complete clearance of Brucella. Therefore, immunomodulatory therapy could be an effective option in cases of brucellosis with pancytopenia that are unresponsive to conventional antibiotic treatment. Further research and clinical evidence are required to confirm and optimize the use of immunomodulatory therapies in patients with brucellosis.

Abstract
INTRODUCTION The myriad presentation of osteoarticular brucellosis make the patient seek the help of general practitioners, orthopaedic and rheumatology specialists. Moreover, the lack of disease-specific symptomatology is the leading cause of the delay in diagnosing osteoarticular brucellosis. Given the increasing number of spinal brucellosis cases across the country, no literature is presented on the systematic management of spinal brucellosis. However, with our experience, we formulated a classification for managing spinal brucellosis. METHODS A single-centred prospective observational study was conducted with 25 confirmed cases of spinal brucellosis. Patients were analysed and graded clinically, serologically, and radiologically and were managed with antibiotics for 10-12 weeks, and if necessary, stabilisation and fusion were done based on the treatment classification devised. All patients were followed up to ensure disease clearance at serial follow-up with relevant investigations. RESULTS The mean age of the study participants was 52.16 ± 12.53 years. According to spondylodiscitis severity code (SSC) grading, four patients belong to grades 1, 12 to grade 2 and 9 to grade 3 at presentation. Erythrocyte sedimentation rate (p = 0.02), c-reactive protein (p < 0.001), Brucella agglutination titers (p < 0.001), and radiological outcomes improved statistically by six months. The treatment duration was individualised according to the patient's response to the treatment, with a mean time of 11.42 ± 2.66 weeks. The mean follow-up period was 14.42 ± 8 months. CONCLUSION High index of suspicion of patients from endemic regions, proper clinical assessment, serological evaluation, radiological assessment, appropriate decision-making (medical/surgical) in treatment, and regular follow-up were the key to successful comprehensive management of spinal brucellosis.

Abstract
BACKGROUND Brucellosis is one of the most common zoonotic diseases in the world. Although cardiovascular complications of human brucellosis account for only 3% of morbidity, they are the leading cause of death. Peripheral vascular disease due to brucellosis is rare and under-reported in the literature. CASE PRESENTATION Two patients with previous brucellosis, both of whom had been treated with anti-brucellosis, were admitted to vascular surgery for thoracic aortic ulcer and abdominal aortic pseudoaneurysm, respectively, with positive IgG antibody to brucellosis and negative IgM antibody to brucellosis, tube agglutination test, and blood culture. These 2 patients were successfully treated with aortic stent-graft implantation and followed up for 8 and 10 weeks without complications. CONCLUSIONS Chronic damage to human blood vessels by brucellosis may not disappear with brucellosis treatment, and peripheral blood vessels should be examined annually in people previously diagnosed with brucellosis. Clinicians in related departments should pay attention to peripheral vascular complications of brucellosis.

Abstract
Brucellosis in sheep and goats has a significant economic and zoonotic impact on the livestock population of Duhok province, Iraq. A total of 681 blood samples from aborted sheep and goats were collected from different flocks in seven districts of Duhok and tested using real-time polymerase chain reaction (RT-PCR). Logistic regression was used for the analysis of the potential risk factors associated with RT-PCR positivity. Results revealed an overall prevalence of 35.45% (CI = 2.57) and 23.8% 18 (CI = 0.44) in sheep and goats, respectively. A statistically significant (p = 0.004) difference in prevalence was found between the two species. RT-PCR detected more positive cases in older-aged animals (OR = 0.7164; p = 0.073). A significant difference was found in RT-PCR positivity in relation to different risk factors, including body condition, treatment taken, and abortion frequency (<0.001). The phylogenetic tree based on the 16S rRNA gene indicated that the isolates belonged to B. melitensis and shared a common ancestor and were genetically related to the United States of America (USA), Greece, China, and Nigeria. This study demonstrates that brucellosis is widely prevalent in the study regions. Therefore, the study suggests the implementation of preventive control measures for brucellosis.

Abstract
BACKGROUND Maternal, fetal, and neonatal complications of brucellosis in pregnant women are probably higher than those in the general population. This comparative study aimed to survey the mentioned complications in pregnant women with positive and negative Brucella serologic tests. STUDY DESIGN This is a prospective cohort study. METHODS In this study, 2160 pregnant women residing in the rural area of Hamadan province were screened for Brucella infection by agglutination test. Then, 106 (4.90%) pregnant women with a positive test (exposed group) were compared with 210 subjects (non-exposed group) who were randomly selected from more than 2000 pregnant women with a negative serological test in terms of maternal, fetal, and neonatal outcomes from October 2018 to March 2020. Data were analyzed by SPSS 20 software at a 95% confidence level. RESULTS The mean age of mothers in both exposed and unexposed groups was 27.84±6.13 and 38.71±6.85 years, respectively. Past medical history of brucellosis, animal contact, and the consumption of unpasteurized dairy products were reported to be 14 (13.2%), 63 (59.4%), and 82 (77.4%), respectively, in the exposed group. The mentioned measures were 3 (1.5%), 109 (51.9%), and 54 (26.9%) in the unexposed group, respectively. Among exposed and unexposed groups, the incidence of abortion was 9 (8.6%) and 5 (2.4%) with P=0.005, intrauterine fetal death was 2 (1.9%) and zero with P=0.211, low birth weight was 10 (10.6%) and 7 (3.4%) with P=0.012, and premature birth was 15 (15.2%) and 18 (8.8%) with P=0.066, respectively. CONCLUSION Brucella infection in pregnant women appears to be associated with the risk of miscarriage, low birth weight, and premature birth.

Abstract
This study aimed to evaluate the diagnostic efficacy of an in-house lateral flow assay (LFA) for the detection of IgM/IgG anti-Brucella antibodies for rapid serodiagnosis of human brucellosis. Three groups of sera samples including 476 from high-risk individuals, 27 from culture-confirmed patients, and 43 from healthy blood donors were used for evaluation of LFA. In comparison with iELISA, the sensitivity, specificity, and accuracy of LFA were >95%, >99%, and 99% respectively. Considering the very good agreement, accuracy, simplicity, and rapidity, LFAs might be useful as a point of care test for the diagnosis of human brucellosis in resource-limited laboratories.

Abstract
Gentamicin is used to treat brucellosis, an infectious disease caused by the Brucella species but the drug faces several issues such as low efficacy, instability, low solubility, and toxicity. It also has a very short half-life, therefore, requiring frequent dosing. Consequently, several other antibiotics are also being used for the treatment of brucellosis as a single dose as well as in combination with other antibiotics but none of these therapies are satisfactory. Nanoparticles in particular polymer-based ones utilizing polymers that are biodegradable and biocompatible for instance PLGA are a method of choice to overcome such drug delivery issues and enable potential targeted delivery. The current study focuses on the evaluation of the structural and dynamical properties of a drug-polymer system consisting of gentamicin drug and PLGA polymer nanoparticles in the water representing a targeted drug delivery system for the treatment of brucellosis. For this purpose, all-atom molecular dynamics simulations were carried out on the drug-polymer systems in the absence and presence of the surfactant bis(2-Ethylhexyl) sulfosuccinate (AOT) to determine the structural and dynamical properties as well as the effect of the surfactant on these properties. We also investigated systems in which the polymer constituents were in the form of monomeric units toward decoupling the primary interactions of the monomer units and polymer effects. The simulation results explain the nature of the interactions between the drug and the polymer as well as transport properties in terms of drug diffusion coefficients, which characterize the molecular behavior of gentamicin-polymer nanoparticles for use in brucellosis.

Abstract
OBJECTIVE Aim to investigate the brucella culture characteristics, diagnosis methods, and clinical characteristics, to provide the laboratory with diagnostic methods and prevention and treatment for brucellosis. METHODS Data of 328 cases of brucellosis from 2012 to 2022 was analyzed, retrospectively. The bacterial culture characteristics, the clinical diagnostic methods, and the complications were analyzed respectively. The infection biomarkers of the brucellosis were analyzed by Receiver operating characteristic curve ROC. RESULTS Among the 328 brucellosis, 78.96 % of cases were men, the median age of the patients was (45.21±13.49) years and the annual incidence in our region was 67/100 000 per year. The diagnostic methods included pathogenic bacteria culture, serological diagnosis, and suspect case were 24.39 %, 47.56 %, and 28.05 %, respectively, sensitivity of combined detection Standard agglutination test (SAT) and the Rose Bengal test (RBT) is 96.2 %. In our work, 80 cases of brucellosis were diagnosed by a bacterial culture which were been identified as Brucella melitensis, blood culture was the main method (78.75 %) and the average positive alarm time was 80.74 (21.6-129) h and all of them were detected in aerobic bottles, followed by synovial fluid, bone marrow, lumbar spine, and joint tissue, puncture fluid and ascites culture which were 6.25 %, 3.75 %, 5.00 %, 5.00 % and 1.25 % respectively. The brucellosis with complications was lumbar spine lesions at 41.46 % cervical spine lesions at 4.60 % and knee joint lesions at 12.8 % and another osteoarthritis. The in-hospital mortality rate of the patients was 0.91 % and all of them were meningitis patients. ROC analysis indicated CRP had high sensitivity and specificity for brucellosis, and when CRP was 1.23mg/ml, the sensitivity and specificity were 0.727 and 0.718 respectively, and the U test also indicated CRP had a significant difference, Z=5.054, p <0.001. CONCLUSIONS Brucellosis is frequently morbidity in 40 + age men, which has been diagnosed by aerobic blood culture, generally bacterial culture, RBT and SAT, epidemiological, and commonly with complications of spine and arthropathy.

Abstract
Brucella suis is an emerging, zoonotic disease predominantly affecting dogs and humans that engage in feral pig hunting in Australia and other countries. Although B. suis infection in dogs shares some clinical similarities to the host-adapted species (B. canis), B. suis remains an incompletely understood pathogen in dogs with limited published data on its pathogenesis and clinical features. This case series describes the presentations, diagnosis, and clinical management of B. suis infection in three dogs: (1) a bitch with dystocia, abortion and mastitis; (2) an entire male dog with septic arthritis and presumptive osteomyelitis; and (3) a castrated male dog with lymphadenitis. Unique features of these cases are reported including the first documented detection of B. suis from milk and isolation from lymph nodes of canine patients, as well as the follow-up of pups born to a B. suis-infected bitch. Consistent with previous reports, all three dogs showed a favourable clinical response to combination antibiotic therapy with rifampicin and doxycycline. Individually tailored drug regimens were required based on the clinical presentation and other factors, including owner expectations and compliance with therapy as well as a zoonotic risk assessment (generally considered low, except around time of whelping). The authors include their recommendations for the clinical management of dogs that are at-risk or seropositive for B. suis with or without clinical signs or laboratory-confirmed infection.

Abstract
Objective To analyze the clinical characteristics and treatment process of 14 patients with aneurysm due to brucellosis, summarize the morbidity characteristics, and improve the knowledge and diagnosis of the disease. Methods The clinical data of patients with aneurysms who were diagnosed to have brucellosis through Rose Bengal Test (RBT), Serum Agglutination Test (SAT), blood culture, and computed tomography angiography from January 2012 to November 2022 in Bethune Hospital, Shanxi Province, China, were retrospectively analyzed, and their clinical characteristics and disease regression findings were summarized. Results Of the 14 patients, 13 were men, and 1 was a woman; the youngest patient was 48-year-old, and the oldest patient was of 74 years. All had a history of smoking. The sites of lesion occurrence included the abdominal aorta (5 patients), abdominal aorta +iliac artery (5 patients), iliac artery (2 patients), thoracic aorta and brachial artery were less common (1 case each). Symptoms in the patients mostly began with abdominal pain, which was accompanied by fever, nausea, and vomiting. Six patients had a clear history of livestock exposure. Fourteen patients showed elevated D-dimer and C-reactive protein levels and decreased hemoglobin and albumin levels. Thirteen of the 14 cases were treated surgically, there were no complications of surgery, and 3 patients were readmitted with recurrence of brucellosis, it is related to the treatment that did not reach the early stage, combination, full dose and full course of treatment, with a mean recurrence time of 8 months. In the telephone follow-up, the patient's recovery proceeded well. Conclusion The present study revealed that the recurrence in male gender, advanced age, smoking and irregular treatment is higher. On the contrast, early intervention, a combination of adequate course of anti-infection treatment and timely surgery can improve the prognosis.

Abstract
Brucellosis is a disease of livestock that is commonly asymptomatic until an abortion occurs. Disease in humans results from contact of infected livestock or consumption of contaminated milk or meat. Brucella zoonosis is primarily caused by one of three species that infect livestock, Bacillus abortus in cattle, B. melitensis in goats and sheep, and B. suis in pigs. To aid in disease prophylaxis, livestock vaccines are available, but are only 70% effective; hence, improved vaccines are needed to mitigate disease, particularly in countries where disease remains pervasive. The absence of knowing which proteins confer complete protection limits development of subunit vaccines. Instead, efforts are focused on developing new and improved live, attenuated Brucella vaccines, since these mimic attributes of wild-type Brucella, and stimulate host immune, particularly T helper 1-type responses, required for protection. In considering their development, the new mutants must address Brucella's defense mechanisms normally active to circumvent host immune detection. Vaccination approaches should also consider mode and route of delivery since disease transmission among livestock and humans is believed to occur via the naso-oropharyngeal tissues. By arming the host's mucosal immune defenses with resident memory T cells (TRMs) and by expanding the sources of IFN-γ, brucellae dissemination from the site of infection to systemic tissues can be prevented. In this review, points of discussion focus on understanding the various immune mechanisms involved in disease progression and which immune players are important in fighting disease.

Abstract
Pediatric neurobrucellosis represents a common anthropozoonosis in endemic areas but only anecdotal reports are available till date. Using appropriate search terms in the database platforms of MEDLINE, SCOPUS and Web of Sciences, we performed a systematic review of all the cases of pediatric neurobrucellosis published in the medical literature till date, in the light of a case report. The protocol was registered under PROSPERO (CRD42022333907). Our search strategy yielded 187 citations of which 51 citations were included. A total of 119 cases were reviewed. Of these cases, eight of them had insufficient data. The most common presentation was meningitis with or without encephalitis (n = 79, 71.2%). A high prevalence of cranial neuropathies (n = 22, 20.7%) was observed in the pediatric population in which abducens palsy was the most common (n = 9, 8.1%). Diagnosis was based on multimodal investigations including standard agglutination test (n = 44, 39.6%), Rose Bengal test (n = 37, 33.3%), blood culture (n = 23, 20.7%), serology (n = 20, 18.0%) and cerebrospinal fluid (CSF) culture (n = 11, 9.9%). Rifampicin-based triple drug regimen was the most commonly employed (83/102, 81.4%). Pediatric neurobrucellosis was associated with greater frequency of sequalae (5.4%), deafness (2.7%) and mortality (2.7%), when compared to that of general population. Neurobrucellosis mimics neuro-tuberculosis in various aspects. The review highlights several unique aspects of this entity in children. A high index of suspicion can ensure prompt diagnosis, timely initiation of management and favorable outcomes.

Methodological choices in brucellosis burden of disease assessments: A systematic review. PLoS Negl Trop Dis 2022; 16:e0010468. [PMID: 36512611 PMCID: PMC9794075 DOI: 10.1371/journal.pntd.0010468] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 12/27/2022] [Accepted: 11/25/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Foodborne and zoonotic diseases such as brucellosis present many challenges to public health and economic welfare. Increasingly, researchers and public health institutes use disability-adjusted life years (DALYs) to generate a comprehensive comparison of the population health impact of these conditions. DALYs calculations, however, entail a number of methodological choices and assumptions, with data gaps and uncertainties to accommodate. Thisreview identifies existing brucellosis burden of disease studies and analyzes their methodological choices, assumptions, and uncertainties. It supports the Global Burden of Animal Diseases programme in the development of a systematic methodology to describe the impact of animal diseases on society, including human health. METHODS/PRINCIPAL FINDINGS A systematic search for brucellosis burden of disease calculations was conducted in pre-selected international and grey literature databases. Using a standardized reporting framework, we evaluated each estimate on a variety of key methodological assumptions necessary to compute a DALY. Fourteen studies satisfied the inclusion criteria (human brucellosis and quantification of DALYs). One study reported estimates at the global level, the rest were national or subnational assessments. Data regarding different methodological choices were extracted, including detailed assessments of the adopted disease models. Most studies retrieved brucellosis epidemiological data from administrative registries. Incidence data were often estimated on the basis of laboratory-confirmed tests. Not all studies included mortality estimates (Years of Life Lost) in their assessments due to lack of data or the assumption that brucellosis is not a fatal disease. Only two studies used a model with variable health states and corresponding disability weights. The rest used a simplified singular health state approach. Wide variation was seen in the duration chosen for brucellosis, ranging from 2 weeks to 4.5 years, irrespective of the whether a chronic state was included. CONCLUSION Available brucellosis burden of disease assessments vary widely in their methodology and assumptions. Further research is needed to better characterize the clinical course of brucellosis and to estimate case-fatality rates. Additionally, reporting of methodological choices should be improved to enhance transparency and comparability of estimates. These steps will increase the value of these estimates for policy makers.

Abstract
Although several factors such as viral and bacterial pathogens, and drugs have been widely reported to be associated with immune thrombocytopenic purpura (ITP), brucellosis is an unusual cause of this disorder. Here, we describe a patient with brucellosis with fever and purpura as the first manifestation of her illness due to immune-mediated severe thrombocytopenia. In this case, ITP responded well to the anti-Brucella treatment with platelet recovery within three days.

Abstract
Background Human brucellosis caused by the facultative intracellular pathogen Brucella spp. is an endemic bacterial zoonosis manifesting as acute or chronic infections with high morbidity. Treatment typically involves a combination therapy of two antibiotics for several weeks to months, but despite this harsh treatment relapses occur at a rate of 5–15%. Although poor compliance and reinfection may account for a fraction of the observed relapse cases, it is apparent that the properties of the infectious agent itself may play a decisive role in this phenomenon. Methodology/Principal findings We used B. abortus carrying a dual reporter in a macrophage infection model to gain a better understanding of the efficacy of recommended therapies in cellulo. For this we used automated fluorescent microscopy as a prime read-out and developed specific CellProfiler pipelines to score infected macrophages at the population and the single cell level. Combining microscopy of constitutive and induced reporters with classical CFU determination, we quantified the protective nature of the Brucella intracellular lifestyle to various antibiotics and the ability of B. abortus to persist in cellulo despite harsh antibiotic treatments. Conclusion/Significance We demonstrate that treatment of infected macrophages with antibiotics at recommended concentrations fails to fully prevent growth and persistence of B. abortus in cellulo, which may be explained by a protective nature of the intracellular niche(s). Moreover, we show the presence of bona fide intracellular persisters upon antibiotic treatment, which are metabolically active and retain the full infectious potential, therefore constituting a plausible reservoir for reinfection and relapse. In conclusion, our results highlight the need to extend the spectrum of models to test new antimicrobial therapies for brucellosis to better reflect the in vivo infection environment, and to develop therapeutic approaches targeting the persister subpopulation. Brucellosis is a zoonosis endemic to many low- and middle-income countries around the world. Therapies recommended by the WHO are comprised of at least two antibiotics for several weeks, sometimes months. Relapses are frequent despite these harsh treatments. The underlying reasons for these relapses, besides reinfection and non-compliance to treatment, are unknown. Our study shows that Brucella abortus can form so called “persisters” in rich broth but also inside macrophages. This small bacterial subpopulation survives antibiotic treatment and resumes growth after removal of the antibiotics and could therefore serve as a reservoir for relapses in human brucellosis. Furthermore, we show that the intracellular lifestyle of Brucella has protective properties against recommended antibiotics as observed for other intracellular pathogens, highlighting the necessity to develop new infection models to assess antibiotic efficacy.

Abstract
Brucellosis, mainly caused by Brucella (B.) melitensis, is associated with a risk of chronification and relapses. Antimicrobial susceptibility testing (AST) standards for B. melitensis are not available, and the agent is not yet listed in the EUCAST breakpoint tables. CLSI recommendations for B. melitensis exist, but they do not fulfill the requirements of the ISO 20776 standard regarding the culture medium and the incubation conditions. Under the third EU Health Programme, laboratories specializing in the diagnostics of highly pathogenic bacteria in their respective countries formed a working group within a Joint Action aiming to develop a suitable method for the AST of B. melitensis. Under the supervision of EUCAST representatives, this working group adapted the CLSI M45 document to the ISO 20776 standard after testing and validation. These adaptations included the comparison of various culture media, culture conditions and AST methods. A Standard Operation Procedure was derived and an interlaboratory validation was performed in order to evaluate the method. The results showed pros and cons for both of the two methods but also indicate that it is not necessary to abandon Mueller-Hinton without additives for the AST of B. melitensis.

Abstract
We report the case of a 58-year-old immunocompetent man from Algeria, who presented to the hospital with fever and hepatic cytolysis. Abdominal computed tomography scan showed a homogeneous splenomegaly and a hypodense 12-mm mass on the posterior wall of the esophagus. After ruling out tuberculosis, the patient was diagnosed with brucellosis. Patient was cured after receiving 6 weeks of oral doxycycline and intravenous gentamicin during the 7 first days of therapy. Such treatment was considered as an acceptable alternative of the recommended first-line therapy. This case illustrates the diagnostic issues in the context of an authentic brucellosis presenting as upper gastrointestinal symptoms, with impaired general condition.

Abstract
Brucella species are intracellular bacterial pathogens, causing the worldwide zoonotic disease brucellosis. Brucella invades professional and nonprofessional phagocytic cells, followed by resisting intracellular killing and establishing a replication permissive niche. Brucella also modulates the innate and adaptive immune responses of the host for its chronic persistence. The complex intracellular cycle of Brucella depends in a major way on multiple host factors, but limited information is available on host and bacterial proteins that play an essential role in the invasion, intracellular replication, and modulation of host immune responses. By employing a small interfering RNA (siRNA) screening, we identified a role for the host protein FBXO22 in the Brucella-macrophage interaction. FBXO22 is the key element in the SCF E3 ubiquitination complex, where it determines the substrate specificity for ubiquitination and degradation of various host proteins. Downregulation of FBXO22 by siRNA or the CRISPR-Cas9 system resulted in diminished uptake of Brucella into macrophages, which was dependent on NF-κB-mediated regulation of phagocytic receptors. FBXO22 expression was upregulated in Brucella-infected macrophages, which resulted in induction of phagocytic receptors and enhanced production of proinflammatory cytokines through NF-κB. Furthermore, we found that FBXO22 recruits the effector proteins of Brucella, including the anti-inflammatory proteins TcpB and OMP25, for degradation through the SCF complex. We did not observe any role for another F-box-containing protein of the SCF complex, β-TrCP, in the Brucella-macrophage interaction. Our findings unravel novel functions of FBXO22 in host-pathogen interaction and its contribution to pathogenesis of infectious diseases.

[PMID: 35335701 PMCID: PMC8954888 DOI: 10.3390/pathogens11030377] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/09/2022] [Accepted: 03/16/2022] [Indexed: 11/21/2022] Open
Abstract
The intracellular pathogens of the genus Brucella are phylogenetically close to Ochrobactrum, a diverse group of free-living bacteria with a few species occasionally infecting medically compromised patients. A group of taxonomists recently included all Ochrobactrum organisms in the genus Brucella based on global genome analyses and alleged equivalences with genera such as Mycobacterium. Here, we demonstrate that such equivalencies are incorrect because they overlook the complexities of pathogenicity. By summarizing Brucella and Ochrobactrum divergences in lifestyle, structure, physiology, population, closed versus open pangenomes, genomic traits, and pathogenicity, we show that when they are adequately understood, they are highly relevant in taxonomy and not unidimensional quantitative characters. Thus, the Ochrobactrum and Brucella differences are not limited to their assignments to different "risk-groups", a biologically (and hence, taxonomically) oversimplified description that, moreover, does not support ignoring the nomen periculosum rule, as proposed. Since the epidemiology, prophylaxis, diagnosis, and treatment are thoroughly unrelated, merging free-living Ochrobactrum organisms with highly pathogenic Brucella organisms brings evident risks for veterinarians, medical doctors, and public health authorities who confront brucellosis, a significant zoonosis worldwide. Therefore, from taxonomical and practical standpoints, the Brucella and Ochrobactrum genera must be maintained apart. Consequently, we urge researchers, culture collections, and databases to keep their canonical nomenclature.

Abstract
Brucellosis is among the most prevalent zoonotic infections in Middle Eastern and North African (MENA) countries, critically impacting human and animal health. A comprehensive review of studies on antibiotic susceptibility and therapeutic regimes for brucellosis in ruminants and humans in the MENA region was conducted to evaluate the current therapeutic management in this region. Different scientific databases were searched for peer-reviewed original English articles published from January 1989 to February 2021. Reports from research organizations and health authorities have been taken into consideration. Brucella melitensis and Brucella abortus have been reported from the majority of MENA countries, suggesting a massive prevalence particularly of B. melitensis across these countries. Several sporadic cases of brucellosis relapse, therapeutic failure, and antibiotic resistance of animal and human isolates have been reported from the MENA region. However, several studies proved that brucellae are still in-vitro susceptible to the majority of antibiotic compounds and combinations in current recommended WHO treatment regimens, e.g. levofloxacin, tetracyclines, doxycycline, streptomycin, ciprofloxacin, chloramphenicol, gentamicin, tigecycline, and trimethoprim/sulfamethoxazole. The current review presents an overview on resistance development of brucellae and highlights the current knowledge on effective antibiotics regimens for treating human brucellosis.

Abstract
Diverse chemicals and some physical phenomena recently introduced in nanotechnology have enabled scientists to develop useful devices in the field of food sciences. Concerning such developments, detecting foodborne pathogenic bacteria is now an important issue. These kinds of bacteria species have demonstrated severe health effects after consuming foods and high mortality related to acute cases. The most leading path of intoxication and infection has been through food matrices. Hence, quick recognition of foodborne bacteria agents at low concentrations has been required in current diagnostics. Lateral flow assays (LFAs) are one of the urgent and prevalently applied quick recognition methods that have been settled for recognizing diverse types of analytes. Thus, the present review has stressed on latest developments in LFAs-based platforms to detect various foodborne pathogenic bacteria such as Salmonella, Listeria, Escherichia coli, Brucella, Shigella, Staphylococcus aureus, Clostridium botulinum, and Vibrio cholera. Proper prominence has been given on exactly how the labels, detection elements, or procedures have affected recent developments in the evaluation of diverse bacteria using LFAs. Additionally, the modifications in assays specificity and sensitivity consistent with applied food processing techniques have been discussed. Finally, a conclusion has been drawn for highlighting the main challenges confronted through this method and offered a view and insight of thoughts for its further development in the future.

Abstract
Brucellae are intracellular sneaky bacteria and they can elude the host's defensive mechanisms, resulting in therapeutic failure. Therefore, the goal of this investigation was to rapid identification of Brucella species collected from animals and humans in Saudi Arabia, as well as to evaluate their resistance to antibiotics. On selective media, 364 animal samples as well as 70 human blood samples were cultured. Serological and biochemical approaches were initially used to identify a total of 25 probable cultured isolates. The proteomics of Brucella species were identified using the MALDI Biotyper (MBT) system, which was subsequently verified using real-time polymerase chain reaction (real-time PCR) and microfluidic electrophoresis assays. Both Brucella melitensis (B. melitensis) and Brucella abortus (B. abortus) were tested for antimicrobial susceptibility using Kirby Bauer method and the E-test. In total, 25 samples were positive for Brucella and included 11 B. melitensis and 14 B. abortus isolates. Twenty-two out of 25 (88%) and 24/25 (96%) of Brucella strains were recognized through the Vitek 2 Compact system. While MBT was magnificently identified 100% of the strains at the species level with a score value more than or equal to 2.00. Trimethoprim-sulfamethoxazole, rifampin, ampicillin-sulbactam, and ampicillin resistance in B. melitensis was 36.36%, 31.82%, 27.27%, and 22.70%, respectively. Rifampin, trimethoprim-sulfamethoxazole, ampicillin, and ampicillin-sulbactam resistance was found in 35.71%, 32.14%, 32.14%, and 28.57% of B. abortus isolates, correspondingly. MBT confirmed by microfluidic electrophoresis is a successful approach for identifying Brucella species at the species level. The resistance of B. melitensis and B. abortus to various antibiotics should be investigated in future studies.

Abstract
Members of the bacterial genus Brucella cause brucellosis, a zoonotic disease that affects both livestock and wildlife. Brucella are category B infectious agents that can be aerosolized for biological warfare. As part of the structural genomics studies at the Seattle Structural Genomics Center for Infectious Disease (SSGCID), FolM alternative dihydrofolate reductases 1 from Brucella suis and Brucella canis were produced and their structures are reported. The enzymes share ∼95% sequence identity but have less than 33% sequence identity to other homologues with known structure. The structures are prototypical NADPH-dependent short-chain reductases that share their highest tertiary-structural similarity with protozoan pteridine reductases, which are being investigated for rational therapeutic development.
