Abstract
Brucellosis is a zoonotic disease endemic in many developing countries, including Türkiye. Among the species that are pathogenic for humans; Brucella melitensis is isolated from livestock animals like sheep and goats, Brucella abortus from cattle and Brucella suis from pigs. Laboratory diagnosis of infection caused by Brucella species with gram-negative coccobacillus morphology; can be made through characteristic culture features, serological tests and molecular methods. Brucellosis, which has a wide distribution of clinical signs and symptoms; can cause various complications by affecting many organs and systems. Among all complications, the probability of thyroid abscess is less than 1%. In this case report; an example of thyroid abscess, one of the rare complications of brucellosis that is not frequently encountered in the literature, was presented. During the physical examination of a 45-year-old female patient who admitted with the complaint of pain in the neck area, fever, neck swelling, redness and pain that increased with palpation were detected. Leukocytosis, lymphopenia, high sedimentation and CRP, low TSH and high T4 values were detected in laboratory tests and subacute thyroiditis was considered as the preliminary diagnosis. Surgical abscess drainage was planned as the patient's clinical findings progressed during follow-up and spontaneous pus discharged from the midline of the neck. The abscess aspirate sample taken during surgical intervention and the blood culture samples taken before were evaluated microbiologically. Microorganisms that did not grow on EMB agar but grew on 5% sheep blood and chocolate agar at the 72-96th hour of incubation of culture plates; were detected to have gram-negative coccobacillus morphology and positive for catalase, oxidase and urease. Although the Wright test was negative with a titer of 1/20, the Rose Bengal test was positive, Coombs test was positive with a titer of 1/160 and the Brucellacapt test was positive with a titer of >1/5120. Microorganisms growing on culture plates were identified as B.melitensis at the species level with specific antisera. As a result of antibiotic susceptibility tests evaluated according to the European Committee on Antimicrobial Susceptibility Testing version 14.0 (EUCAST v14.0), the isolate was susceptible to rifampicin, doxycycline, gentamicin and trimethoprim-sulfamethoxazole at standart dosing regimen and susceptible to ciprofloxacin and levofloxacin at increased exposure. The patient, who was started on doxycycline and rifampicin combination treatment, was discharged without any complaints. In the diagnosis of infection due to Brucella species, which is one of the pathogens that early diagnosis and initiation of treatment greatly affects the prognosis; in addition to culture, which is the gold standard method, serological tests are also very important. If diagnosis is delayed, complications may develop due to involvement in almost every part of the body, depending on the affected organs and systems. In areas where brucellosis is endemic, patients with symptoms such as neck swelling, shortness of breath and difficulty in swallowing, thyroid tissue involvement due to brucellosis should definitely be considered etiologically.

Abstract
BACKGROUND Brucellosis is an infectious zoonotic bacterial disease of humans and other animals. In the Republic of South Africa (RSA), animal brucellosis is widespread and the current available data on the prevalence of this disease rely solely on serological testing. The primary limitation of brucellosis serology is the lack of discriminatory powers to differentiate between Brucella species and biovars as well as the cross-reactivity observed with other Gram-negative bacteria. AIM The aim of this study was to conduct a retrospective laboratory-based survey on Brucella species and biovars isolated from various animal species in SA between 2008 and 2018. MATERIAL AND METHODS The isolation of Brucella species and biovar typing was performed using conventional microbiological techniques. RESULTS AND DISCUSSION A total of 963 strains of Brucella species were included in this study with a frequency of detection for B. abortus (n = 883; 91.6%) followed by B. melitensis (n = 42; 4.4%), B. ovis (n = 29; 3.0%) and B. canis (n = 9; 0.9%). Of the 883 strains of B. abortus, 90.1% were typed as B. abortus biovar-1 while 5.7% as B. abortus biovar-2, and 3.3% and 0.5% were B. abortus S19 and B. abortus RB51 vaccine strains, respectively. Among the 42 B. melitensis strains, 71.4% were reported as B. melitensis biovar-1 and 26.2% as B. melitensis biovar-3 while 2.4% was B. melitensis biovar-2. CONCLUSION A retrospective study, such as this one, provides useful information that can be critical in formulating policies and strategies for the control and eradication of brucellosis in animal populations in RSA.

Abstract
Brucellosis is a zoonotic infectious disease caused by Brucella infection. Outer membrane protein 25 (Omp25) is closely related to the virulence and immunogenicity of Brucella. However, the molecular mechanism of Omp25 affecting Brucella-mediated macrophage autophagy remains unclear. Our previous study reported that four miRNAs (the upregulation of mmu-miR-146a-5p and mmu-miR-155-5p and downregulation of mmu-miR-149-3p and mmu-miR-5126) were confirmed and revealed the differentially expressed genes (DEGs) profile in RAW264.7 macrophage cells infected with Brucella melitensis Omp25 deletion mutant (∆Omp25 B. melitensis). Here, we predicted the target genes of the four miRNAs by TargetScan, miRanda, and PicTar. GO and KEGG were used for functional enrichment analysis of DEGs profile to reveal the autophagic pathway-associated genes. The overlapped genes, which drawn the autophagic pathway-associated miRNA-mRNA networks by cytoscape software, were identified by intersecting with the predicted target genes and autophagic pathway-associated DEGs. qRT-PCR was performed to validate the mRNAs of networks. The results showed that the autophagic pathway-associated networks of mmu-miR-149-3p-Ptpn5, mmu-miR-149-3p-Ppp2r3c, and mmu-miR-146a-5p-Dusp16 were identified in RAW264.7 macrophage cells infected with ∆Omp25 B. melitensis. Our findings are of great significance in elucidating the function of Omp25, revealing the infection mechanism of Brucella and prophylaxising and treating brucellosis.

Abstract
Brucella melitensis and Brucella abortus account for almost all cases of brucellosis in Turkish population. We developed a fourplex quantitative real-time PCR (qPCR) assay for the electrophoresis-free, rapid and cost-effective differentiation of B. abortus and B. melitensis from the other Brucella spp. The 4-plex species differentiation assay was combined with a qPCR assay targeting 17 different single nucleotide polymorphism (SNP) loci in Brucella genomes. This combination resulted in a 21 Variable Genome Loci (21-VGL) qPCR assay for high resolution genotyping of B. abortus and B. melitensis. A total of 486 Brucella was analyzed using the qPCR assay to create a 21-VGL profile database. The database contained the profiles of 55 B. abortus, 352 B. melitensis, 3 B. ceti, 6 B. neotomae, 7 B. ovis, 6 B. pinnipedialis, 44 B. suis and 13 B. canis strains. The 21-VGL Brucella genotyping clearly distinguished B. abortus, B. melitensis, B. neotomae and B. ovis. The 21-VGL approach could not distinguish B. pinnipedialis from B. ceti and some B. suis genotypes from B. canis. The results revealed that more than 99% of the Brucella isolates in Turkey were B. melitensis and 21-VGL genotyping can be reduced to 8-VGL B. melitensis genotyping without any loss of genotyping resolution. To our knowledge, we introduced the fastest and the lowest-cost B. abortus and B. melitensis genotyping and species differentiation methodology in the literature.

Abstract
The intracellular pathogenic bacteria belonging to the genus Brucella must cope with acidic stress as they penetrate the host via the gastrointestinal route, and again during the initial stages of intracellular infection. A transcription-level regulation has been proposed to explain this but the specific molecular mechanisms are yet to be determined. We recently reported a comparative transcriptomic analysis of the attenuated vaccine Brucella melitensis strain Rev.1 against the virulent strain 16M in cultures grown under either neutral or acidic conditions. Here, we re-analyze the RNA-seq data of 16M from our previous study and compare it to published transcriptomic data of this strain from both an in cellulo and an in vivo model. We identify 588 genes that are exclusively differentially expressed in 16M grown under acidic versus neutral pH conditions, including 286 upregulated genes and 302 downregulated genes that are not differentially expressed in either the in cellulo or the in vivo model. Of these, we highlight 13 key genes that are known to be associated with a bacterial response to acidic stress and, in our study, were highly upregulated under acidic conditions. These genes provide new molecular insights into the mechanisms underlying the acid-resistance of Brucella within its host.

Abstract
Objective: To understand the molecular characteristics and correlation among isolated strains of Brucella melitensis (BM) so as to improve the strategies on prevention and control of the disease in Jiangxi province. Methods: A total of 25 strains of BM isolated from human in 17 counties of Jiangxi province were analyzed by multiple locus variable-number tandem repeat analysis (MLVA) method. Results: A total of 25 strains of BM were classified into 24 independent genotypes with similarities between 67.00% and 100.00% and Simpson index between 0.000 and 0.773. There were 3 genotypes in MLVA8, including 60.00% (15/25) as 42 genotype, 32.00% (8/25) as 43 genotype, and 8.00% (2/25) as 63 genotype, respectively. There were 7 genotypes in MLVA11 identified, with 116 genotype and 125 genotype the main genotypes, accounting for 56.00% (14/25) of all the identified strains. Conclusions: Genes from all the 25 strains of BM that isolated from human being were with high genetic diversities, and various, genotypes. However, no obvious epidemiological correlation was noticed among these strains, indicating the complexity of the source of infection on Brucella in Jiangxi province.

Abstract
BACKGROUND Brucellosis, a major health problem in developing countries, is a multisystem infection with a broad spectrum of clinical manifestations. Hematological complications, ranging from an intravascular coagulopathy to mild homeostasis disorders (such as gammopathy), have been reported in brucella infection. These signs and symptoms may lead to misdiagnosis of brucellosis with other hematological diseases. CASE A 65-year-old male whose occupation was shepherding was referred to our hospital as a known case of multiple myeloma with continuous fever, muscle weakness, and night sweating after taking 2 courses of chemotherapy. The laboratory diagnosis of multiple myeloma had been based on the observation of a high percent of plasma cells in the bone marrow aspiration. At follow- up, the result of patient's fever workup, with 2 sets of blood cultures, was positive for Brucella melitensis. Isolated brucella was confirmed as B. melitensis by 16S rRNA sequencing. Brucellosis serologic test was performed by agglutination test and positive results were obtained. The patient was discharged with the cessation of fever and general improvement after the end of the parental treatment phase of brucella bacteremia. CONCLUSIONS Brucella infection may cause a severe disease, mimicking a primary hematological disease, which could complicate the correct diagnosis. In brucellosis cases, due to the wide range of symptoms, in addition to cultivation and serological methods, molecular methods should also be used to prevent inappropriate diagnosis and additional costs.

Abstract
RATIONALE Childhood brucellosis is a significant community health problem. It may imitate other conditions and may be misdiagnosed. Pulmonary involvement is a rare complication of childhood brucellosis. PATIENT CONCERNS A 23-month-old child was referred to our hospital with a 3-week history of fevers and cough. He was initially diagnosed with pneumonia. DIAGNOSES AND INTERVENTIONS Conventional antibiotic treatment was ineffectual. Total leukocyte count was 10,300/mm, hemoglobin was 8.5 g/dL, and platelet count was 250,000/mm. The erythrocyte sedimentation rate and procaicltonin were 25 mm/h and 0.12 ng/mL, respectively. Chest radiography showed pneumonic infiltrate in both lungs.The initial bacteriologic test results were negative. Ten days after admission, Brucella melitensis were isolated from the second blood culture. This child was cured with the 2-drug regimen (rifampin+trimethopicin-sulfamethoxazole) for 6 weeks. OUTCOMES The child recovered well with no occurrence of complications. The child remained asmptomatic without any signs or symptoms at a follow-up of 1 year. LESSONS Non-specific findings of pulmonary brucellosis in children often make diagnosis difficult. The second blood culture is essential. In endemic areas, children with fevers and cough should be included in the diagnosis in cases of pulmonary brucellosis.

Abstract
Brucella abortus and B. melitensis have been reported in several studies in animals in Zimbabwe but the extent of the disease remains poorly known. Thus, characterizing the circulating strains is a critical first step in understanding brucellosis in the country. In this study we used an array of molecular assays including AMOS-PCR, Bruce-ladder, multiple locus variable number tandem repeats analysis (MLVA) and single nucleotide polymorphisms from whole genome sequencing (WGS-SNP) to characterize Brucella isolates to the species, biovar, and individual strain level. Sixteen Brucella strains isolated in Zimbabwe at the Central Veterinary laboratory from various hosts were characterized using all or some of these assays. The strains were identified as B. ovis, B. abortus, B. canis and B. suis, with B. canis being the first report of this species in Zimbabwe. Zimbabwean strains identified as B. suis and B. abortus were further characterized with whole genome sequencing and were closely related to reference strains 1330 and 86/8/59, respectively. We demonstrate the range of different tests that can be performed from simple assays that can be run in laboratories lacking sophisticated instrumentation to whole genome analyses that currently require substantial expertise and infrastructure often not available in the developing world.

This is a case report of a 76-year-old man with spondylodiscitis caused by Brucella melitensis. He was admitted to hospital due to backpain, weight loss and elevated C-reactive protein level. MRI showed signs of multifocal spondylodiscitis, and blood cultures yielded B. melitensis. The patient was most likely infected through consumption of unpasteurised camel milk. Antibiotic treatment was initiated with good effect. Although bru-cellosis is rare in Denmark, correct diagnosis is important due to the high morbidity, the specific antibiotic treatment needed and the necessary laboratory precautions.

Abstract
OBJECTIVE This study investigated the association of Brucella seropositivity and spontaneous abortions in human population in the city of Mwanza, Tanzania. RESULTS A comparative cross sectional study which used 148 sera from women with spontaneous abortion and 250 sera from full-term delivered women was conducted in July 2017. Detection of Brucella abortus and Brucella melitensis antibodies was done using slide agglutination test. Data were analyzed using STATA version 13 software. The median age of the study participants was 25 (interquartile range 21-30) years. The overall seropositivity of Brucella antibodies was significantly higher among sera from women with spontaneous abortion than full term delivered women; (86/148, 58.1%: 95% CI 50-66 vs. 65/250, 26%: 95% CI 18-33, P < 0.001). Seropositivity of B. abortus was significantly higher among sera from women with spontaneous abortion than full-term delivered women (31.8% vs. 10.8%, P < 0.001). Women with abortion had 3.59 odds of being brucella seropositive compared to full term women (OR: 3.59, 95% CI; 2.25-5.74, P < 0.001). Seropositivity of Brucella antibodies is significantly higher among women with spontaneous abortion than full-term delivered women necessitating a need to investigate the relationship between Brucellosis and adverse pregnancy outcomes.

Abstract
INTRODUCTION Brucellosis is a rare infection in France and its wide spectrum of clinical presentation can be a diagnostic challenge. CASE REPORT We report here the case of a 76-year-old Tunisian-born woman referred for fatigue, weight loss, intermittent fever, and pain in the right upper quadrant, along with hepatic lesions on CT-scan, MRI and PET-FDG suggesting malignant lesions. However blood cultures were positive to Brucella melitensis leading to a diagnosis of hepatic brucelloma. CONCLUSION Hepatic abscesses are rare in brucellosis. This infection has to be evoked in patients coming from endemic areas even with atypical manifestations.

Abstract
Background Kazakhstan belongs to countries with a high level of brucellosis among humans and farm animals. Although antibiotic therapy is the main way to treat acute brucellosis in humans there is still little information on a circulation of the antibiotic-resistant Brucella strains in the Central Eurasia. In this article we describe an occurrence of the drug resistance of Brucella melitensis isolates in Kazakhstan which is among the largest countries of the region. Methods Susceptibilities to tetracyclin, gentamycin, doxycyclin, streptomycin and rifampicin were investigated in 329 clinical isolates of Brucella melitensis using E-test method. Results All isolates were susceptible to streptomycin, tetracycline and doxycycline. 97.3% of the Brucella isolates were susceptible to gentamycin, although only 37.4% of isolates were susceptible to rifampicin. 21.9% of isolates had intermediate resistance, and 26.4% of isolates were resistant to this antibacterial drug. Conclusion Isolates of Brucella melitensis circulating in Kazakhstan are susceptible to streptomycin, doxicyclin, tetracyclin and gentamycin. At the same time the resistance to rifampicin is widespread, almost half of the isolates were rifampicin-resistant (including the intermediate resistance).

Abstract
Caprine brucellosis is a chronic infectious disease caused by the gram-negative cocci-bacillus Brucella melitensis. Middle- to late-term abortion, stillbirths, and the delivery of weak offspring are the characteristic clinical signs of the disease that is associated with an extensive negative impact in a flock's productivity. B. melitensis is also the most virulent Brucella species for humans, responsible for a severely debilitating and disabling illness that results in high morbidity with intermittent fever, chills, sweats, weakness, myalgia, abortion, osteoarticular complications, endocarditis, depression, anorexia, and low mortality. Historical observations indicate that goats have been the hosts of B. melitensis for centuries; but around 1905, the Greek physician Themistokles Zammit was able to build the epidemiological link between "Malta fever" and the consumption of goat milk. While the disease has been successfully managed in most industrialized countries, it remains a significant burden on goat and human health in the Mediterranean region, the Middle East, Central and Southeast Asia (including India and China), sub-Saharan Africa, and certain areas in Latin America, where approximately 3.5 billion people live at risk. In this review, we describe a historical evolution of the disease, highlight the current worldwide distribution, and estimate (by simple formula) the approximate costs of brucellosis outbreaks to meat- and milk-producing farms and the economic losses associated with the disease in humans. Successful control leading to eradication of caprine brucellosis in the developing world will require a coordinated Global One Health approach involving active involvement of human and animal health efforts to enhance public health and improve livestock productivity.

Abstract
OBJECTIVE To evaluate a hypervariable octameric oligonucleotide fingerprints (HOOF-Prints) assay for identification of and discrimination between wild-type and vaccine strains of Brucella melitensis. SAMPLE Brucella melitensis vaccine strain M5 and wild-type strain M43. PROCEDURES 8 pairs of primers (alterable, octameric nucleotides) were designed on the basis of a biological analysis of 8 flanking sequences in the DNA of B melitensis. The HOOF-Prints technique was used to identify wild-type and vaccine strains of B melitensis. Phylogenetic analysis of short, polymorphic fragments of DNA from B melitensis strains M5 and M43 was performed. RESULTS Variable-number tandem repeat DNA segments of B melitensis vaccine strain M5 and wild-type strain M43 were successfully amplified by means of PCR assay. All target gene fragments ranged in size from 100 to 300 bp. Separate phylogenetic analysis of each Brucella strain revealed considerable differences between the vaccine and wild-type strains. CONCLUSIONS AND CLINICAL RELEVANCE The results of this study suggested the HOOF-Prints assay may be useful for discriminating vaccine strains of B melitensis from wild-type strains. This ability could allow discrimination between animals that are seropositive because of vaccination against B melitensis and those that are seropositive because of B melitensis infection and could decrease the likelihood of importing Brucella-infected animals.

Abstract
Brucellosis, a worldwide common bacterial zoonotic disease, has become quite rare in Northern and Western Europe. However, since 2014 a significant increase of imported infections caused by Brucella (B.) melitensis has been noticed in Germany. Patients predominantly originated from Middle East including Turkey and Syria. These circumstances afforded an opportunity to gain insights into the population structure of Brucella strains. Brucella-isolates from 57 patients were recovered between January 2014 and June 2016 with culture confirmed brucellosis by the National Consultant Laboratory for Brucella. Their whole genome sequences were generated using the Illumina MiSeq platform. A whole genome-based SNP typing assay was developed in order to resolve geographically attributed genetic clusters. Results were compared to MLVA typing results, the current gold-standard of Brucella typing. In addition, sequences were examined for possible genetic variation within target regions of molecular diagnostic assays. Phylogenetic analyses revealed spatial clustering and distinguished strains from different patients in either case, whereas multiple isolates from a single patient or technical replicates showed identical SNP and MLVA profiles. By including WGS data from the NCBI database, five major genotypes were identified. Notably, strains originating from Turkey showed a high diversity and grouped into seven subclusters of genotype II. MLVA analysis congruently clustered all isolates and predominantly matched the East Mediterranean genetic clade. This study confirms whole-genome based SNP-analysis as a powerful tool for accurate typing of B. melitensis. Furthermore it allows special allocation and therefore provides useful information on the geographic origin for trace-back analysis. However, the lack of reliable metadata in public databases often prevents a resolution below geographic regions or country levels and corresponding precise trace-back analysis. Once this obstacle is resolved, WGS-derived bacterial typing adds an important method to complement epidemiological surveys during outbreak investigations. This is the first report of a detailed genetic investigation of an extensive collection of B. melitensis strains isolated from human cases in Germany.

Abstract
BACKGROUND Neurobrucellosis is a rare complication of brucellosis, a bacterial zoonotic disease endemic in regions such as the Middle East. It is important to be alert for this imported disease in the Netherlands as well, especially among migrants. CASE DESCRIPTION A 14-year-old boy from Syria presented with headache, vomiting and weight loss. Brucella melitensis was identified in the cerebrospinal fluid. The patient's condition deteriorated despite antibiotic treatment, particularly neurologically, and imaging revealed a newly developed hydrocephalus. The symptoms disappeared after placement of a temporary external ventricular drain. The patient made a complete recovery following 8 months of continual antibiotic therapy. CONCLUSION Diagnosis and treatment were delayed, partly because there were no medical records available, previous treatment had been interrupted when the patient fled the country, and the language barrier. Knowledge of previous medical history and of the epidemiology of infectious diseases in the land of origin is particularly important when treating migrants. Treating brucellosis with antibiotics can lead to clinical deterioration due to a Jarisch-Herxheimer-like phenomenon.

Abstract
The brucellosis with multi-organ involvement in a patient with a history of the composite aortic graft (Bentall procedure) and Hepatitis B infection is rare. A 35-year-old man presented to us with fever and loss of consciousness. Four years ago, he was IDU and underwent cardiac surgery because of endocarditis. Recently lumbar spondylodiscitis was diagnosed. The Wright (1/320) and Coombs Wright tests (1/640) were positive. After CNS imaging, lumbar puncture was done. The CSF pleocytosis was lymphocyte dominant. In cardiac echocardiography, large vegetation on prosthetic aortic valve leaflets was seen. The brain MRI was reported abnormal. Treatment of brucellosis started with Ceftriaxone, Doxycycline, Rifampin and Gentamycin. After 4 days, he became oriented, and fever was disappeared then we continued the treatment for 16 days. The patient discharged and followed by daily phone calls. As symptoms of abdominal pain and jaundice were presented on the fifth day, he re-admitted. The patient expired because of hepatorenal and cardiac insufficiency. Drug side effects, activation of Hepatitis B and embolism of cardiac vegetation to other organs were suspected causes of death. We do not suggest medical therapy without cardiac surgery in such cases. When combination therapy is necessary for brucellosis in an HBsAg-positive patient, hepatitis virus activity should be assess by HBV-DNA PCR and the dose of drugs with known hepatotoxic effects such as rifampin and co-trimoxazole should be adjust. Combination therapy with quinolones instead of hepatoxic drugs is one of our suggustions.

Abstract
Pleural involvement is a rare presentation of brucellosis. We report a patient referred for the evaluation of fever, right-sided pleural effusion and hilar lymph node enlargement. The pleural fluid revealed exudative characteristics with the predominance of neutrophils. Brucella melitensis was isolated from bone marrow, pleural effusion and blood cultures. The diagnosis was also confirmed by demonstration of a high Brucella agglutinin titre. The patient was successfully treated with rifampicin and doxicycline for three months.

Abstract
This retrospective study included seven paediatric cases aged from 4 to 14 (10.2±3.4) years with pathologically proved haemophagocytic lymphohistiocytosis from a single institution during 2009 and 2013. Over this time period, 496 patients with brucellosis were diagnosed. None of the patients (3 boys and 4 girls) had a history of any haematologic disorder. All patients had an anamnesis for recently consumed unpasteurised homemade dairy products or had a contact history with sheep and/or cows. The diagnosis of brucellosis was confirmed by standard tube agglutination test in all patients; titres were 1: 1280 in seven patients. Blood culture was positive for Brucella melitensis in three patients (42%). Bone marrow cultures were positive for B. melitensis in four patients (57%). Fever was present in all patients (100%) with haemophagocytic lymphohistiocytosis. The other most common symptoms were malaise, myalgia, anorexia, sweating and weight loss. In addition, sweating was observed in five patients, and lymphadenopathy, petechiae, and weight loss were observed in one patient. Hepatomegaly, splenomegaly, and hepatosplenomegaly were found in four (57%), six (85%) and four (57%), patients, respectively. Haemophagocytosis was documented in bone marrow examinations of all children except in two cases. All patients recovered completely, and their peripheral blood counts returned to normal by 2 to 4 weeks after antibiotic treatment of brucellosis.

Abstract
BACKGROUND Southern Israel is endemic for Brucella melitensis (BM) infection. AIMS This study aims to describe clinical manifestations and laboratory abnormalities in hospitalized adults with BM-bacteremia and to assess the relationship between various laboratory parameters, outcomes and complications of brucellosis. METHODS This is a retrospective study. All BM bacteremic patients hospitalized in the Soroka University Medical Center (SUMC) during 2006-2011 were included. Demographic, clinical data and laboratory results were collected from the medical records. RESULTS A total of 114 patients were included in the study, mostly of Bedouin-Arab origin (92%). The average age was 44 years (±18.4) and included 62 females (54%) of whom 11 were pregnant. Most of the subjects were exposed to sheep or their milk or meat products. The main symptoms included fever, arthralgia, myalgia, headache, and low back pain. Complications were present in 22 patients (19%): arthritis and osteomyelitis (59%), spontaneous abortion (36% of pregnant woman), endocarditis and epididymitis. The incidence of complications was correlated to anemia and leukopenia (p=0.03) and to a low neutrophil count (p=0.009). A decrease of albumin by one unit correlated with an increased hospitalization length by 1.9 days; older age also correlated with a prolonged stay. Complications were present in 45% of pregnant women vs. 10% in non-pregnant women (p=0.011. Relapse occurred in nine patients (8%); only one of these received adequate antibiotic treatment. CONCLUSIONS MB-bacteremia in southern Israel occurs mainly in Bedouin-Arabs after exposure to sheep or their products. Older age and low albumin levels increase hospitalization. Leukopenia, mainly low neutrophil count, and low thrombocyte count can predict complications. Pregnant women have a higher incidence of complications. Relapse is rare under adequate antibiotic treatment.

Abstract
PURPOSE Brucella is an intracellular gram-negative pathogen that acts as a facultative parasite. B. Melitensis endogenous endophthalmitis is quite rare. We herein report an unusual case of B. melitensis endophthalmitis with a good outcome after appropriate management. METHODS A retrospective interventional case report of an 18-year-old boy who had unexplained interrupted fever and malaise for the past 4 months and was being treated as a case of fever of unknown origin. He presented with a 10-day history of pain and loss of vision in the left eye. Visual acuity in the left eye at time of presentation was counting fingers near face. Extensive anterior chamber reaction and flare, as well as, vitritis were found on examination. All blood and urine investigations and radiological imaging were negative. RESULTS A diagnostic/therapeutic vitrectomy with antibiotic injection helped in identifying the offending organism and controlling the inflammation. Vitrectomy sample revealed B. melitensis with no sensitive result. Patient recovered vision in his eye to 20/150. Eye examination revealed a quiet eye, with flat retina and some retinal pigment epithelial changes at macula. CONCLUSION B. melitensis endophthalmitis is a rarely encountered disease entity. High suspicion and prompt management with vitrectomy and appropriate antibiotic injection was successful in salvaging the patient's eye.

Abstract
Brucellosis is a zoonosis of economic importance that reduces productivity in livestock enterprises as it induces abortion in infected animals. A study was designed aimed at detecting Brucella in blood and lymph node specimens from camels by the use of real-time PCR in Iran. Sample collection and DNA extraction were done on blood (n = 135) and lymph node (n = 135) samples collected from 135 camels (abattoir survey) from both sexes at various ages in different seasons. The real-time PCR for species differentiation was based on unique genetic loci of B. melitensis and B. abortus. The regions were chosen for the construction of primers and TaqMan® probes for species differentiation: BMEII0466 gene for B. melitensis and Bru-Ab2_0168 gene for B. abortus. Brucella spp. were identified in 18 (13.33%) blood samples and 4 (2.97%) lymph node samples. This method showed to be effective in detecting B. abortus and B. melitensis in blood and lymph samples respectively. Brucella abortus was detected in 3 (2.22%) blood samples but was however, not detected in the lymph node samples. Brucella melitensis was only observed in 4 (2.97%) lymph node samples. Significant differences were observed on the blood prevalence of unknown Brucella spp. in different age groups and seasons (P < 0.05). However, there were no significant differences observed on the prevalence of B. abortus, B. melitensis, unknown Brucella spp. in different age groups, sex and seasons (P > 0.05). Therefore, Brucella was detected in apparent healthy camels slaughtered at an abattoir in Iran and this recommends the significance of the detection of Brucella in camels, since the infected camels appear to be healthy.

Abstract
BACKGROUND Brucella melitensis is the most important pathogenic species of Brucella spp. which affects goats and sheep and causes caprine and ovine brucellosis, respectively. Serological tests for diagnosis of brucellosis such as Rose Bengal plate test (RBPT) and enzyme-linked immunosorbent assay (ELISA) usually utilize smooth lipopolysaccharides (S-LPS) as a diagnostic antigen which could give false positive serological reactions. Outer membrane proteins (OMP) of B. melitensis have been used as alternative diagnostic antigens rather than S-LPS for differential serological diagnosis of brucellosis, mainly in ELISA with single recombinant OMP (rOMP) as a diagnostic antigen. Nevertheless, the use of single format mainly showed lack of sensitivity against the desired rOMP. Therefore, this study aimed to determine whether a newly developed rOMPs indirect ELISA (rOMPs I-ELISA), based on combination of rOMP25, rOMP28 and rOMP31of B. melitensis, has a potential benefit for use in the serodiagnosis of brucellosis. METHODS In this study, omp25, omp28 and omp31 of B. melitensis were cloned and expressed using prokaryotic pET-32 Ek/LIC system and their respective rOMPs were combined as one coating antigen to develop rOMPs I-ELISA. Three groups of BALB/c mice were used to elicit antibody response. Group 1, infected with B. melitensis strain 0331 field strain; group 2, injected with B. melitensis Rev.1 vaccine strain and group 3, infected with Yersinia enterocolitica O:9. Antibody responses in three groups of mice were investigated using Rose Bengal plate test (RBPT) and rOMPs I-ELISA. RESULTS The production of rOMP25, rOMP28 and rOMP31 of B. melitensis were achieved and Western immunoblotting analysis demonstrated their reactivity. The RBPT was unable to differentiate the vaccinated mice (group 2) and mice infected with Y. enterocolitica O:9 (group 3) and categorized them wrongly as positive for brucellosis. In contrast, the rOMPs I-ELISA was able to differentiate the mice infected with B. melitensis strain 0331 (group 1) from both of group 2 and group 3, and recorded 100% sensitivity and 100% specificity. CONCLUSIONS The results of this study suggested that rOMPs of B. melitensis has potential diagnostic ability to differentiate the FPSR in serological diagnosis of brucellosis.

Abstract
Although Malta is historically linked with the zoonosis brucellosis, there had not been a case of the disease in either the human or livestock population for several years. However, in July 2013 a case of human brucellosis was identified on the island. To determine whether this recent case originated in Malta, four isolates from this case were subjected to molecular analysis. Molecular profiles generated using multilocus sequence analysis and multilocus variable number tandem repeat for the recent human case isolates and 11 Brucella melitensis strains of known Maltese origin were compared with others held on in-house and global databases. While the 11 isolates of Maltese origin formed a distinct cluster, the recent human isolation was not associated with these strains but instead clustered with isolates originating from the Horn of Africa. These data was congruent with epidemiological trace-back showed that the individual had travelled to Malta from Eritrea. This work highlights the potential of using molecular typing data to aid in epidemiological trace-back of Brucella isolations and assist in monitoring of the effectiveness of brucellosis control schemes.

Abstract
Although liver involvement is frequently seen in brucellosis, acute hepatitis is a rare clinical entity. In its progress, haematological findings are non-specific and vary in respect to severity. In this paper, we present a case of brucellosis with acute hepatitis and bicytopenia without anaemia. A 19-year-old man presented with a 2-week history of fever, sweating, low back and leg pain, lassitude, loss appetite, nausea and vomiting. He gave a history of raw milk ingestion and animal contact. Physical examination showed signs of icteric skin and sclera, tenderness in the right hypochondriac region and hepatosplenomegaly. On admission to hospital, laboratory tests showed WBC 3500/mmc (polymorphs 63% and lymphocytes 33%), haemoglobin 13.8 g/dL, platelet 89000/mmc, erythrocyte sedimentation rate 19 mm/h, and C-reactive protein 21.7 mg/dL (N<0.8 mg/dL). Biochemical tests were as follows: AST 771 U/L, ALT 471 U/L, ALP 355 U/L, GGT 432 U/L, total bilirubin 2.61 mg/dL, direct bilirubin 1.45 mg/dL and albumin 3.7 g/dL. Viral hepatitis markers were found to be negative (HBsAg, anti-HBc total, anti-HBc IgM, anti-HAV IgM, and anti-HCV). Blood culture grew Brucella melitensis. Leukopenia and thrombocytopenia returned to normal levels at the 7th and 14th day of his admission, respectively. Liver function tests improved at the 28th day. Treatment of the brucellosis was performed with antibiotics (tetracycline 500 mg orally four times daily for 6 weeks and streptomycin 1 g IM once daily for 21 days). Finally, a case of brucellosis with acute hepatitis and bicytopenia was treated with a successful outcome. In conclusion, we suggest that due consideration be taken of bicytopenia/pancytopenia and acute hepatitis in brucellosis cases in Turkey, an endemic region.

Abstract
Molecular approaches have been investigated to overcome difficulties in identification and differentiation of Brucella spp. using conventional phenotypic methods. In this study, high-resolution melt (HRM) analysis was used for rapid identification and differentiation of members of Brucella genus. A total of 41 Brucella spp. isolates from human brucellosis were subjected to HRM analysis using 4 sets of primers, which identified 40 isolates as Brucella melitensis and 1 as Brucella canis. The technique utilized low DNA concentration and was highly reproducible. The assay is shown to be a useful diagnostic tool, which can rapidly differentiate Brucella up to species level.

Abstract
OBJECTIVE To understand the genetic and epidemiologic characteristic of Brucella (B.) melitensis strains isolated in Guizhou province in 2010-2012. METHODS B. genus specific BCSP31-PCR and species-specific AMOS-PCR were used to identify the bacteria strain, while the identified strains were analyzed under MLVA-16 and cluster analysis of B. melitensis strains. The strains were isolated from Guizhou and other provinces. RESULTS Six B. melitensis strains were identified as B. melitensis using the BCSP31-PCR and AMOS-PCR. Data from the MLVA-16 analysis revealed the differences of repeated numbers at parts of the VNTR locus in the six strains isolated in Guizhou province. The six strains from Guizhou province and 105 B. melitensis strains from other province could be divided into 72 MLVA types(MT). Strain ZY and ZA from Guizhou province were typed as MT63, and LL3, LL4 and LL11 were typed as MT67, while strain SQ was typed as MT72. Data from the clustering analysis showed that ZY,ZA, LL3, LL4 and LL9 were most closely clustered with B. melitensis isolates from Yunnan, Fujian and Guangdong provinces, but strain SQ was genetically remote from other strains. CONCLUSION PCR methods, combined with MLVA-16, identified the six B. melitensis strains isolated in Guizhou province in 2010-2012 as B. melitensis biovar 3, with the genetic diversity of the strains showed. Six strains were closely related to the B. melitensis strains from Yunnan, Fujian and Guangdong provinces. The results of this study provided scientific basis for the control and prevention of Brucellosis in Guizhou province.

Abstract
Cases of brucellosis were diagnosed in 3-month-old twins and their mother. An epidemiologic survey suggested that raw sheep or goat meat might be the source of Brucella melitensis infection. This finding implies that the increasing threat of brucellosis might affect low-risk persons in urban settings in China.

Abstract
Human brucellosis, a zoonotic infection, may present with a range of symptoms but is rarely described as a cause of surgical site infections. We present the first reported case of Brucella melitensis causing sternal osteomyelitis of a midline sternotomy for a coronary artery bypass graft. The operation was performed in a non-endemic country but the patient had travelled to Syria immediately before surgery, where the infection was assumed to have been acquired. The infection resolved following treatment with doxycycline, rifampicin and gentamicin. We review the literature for surgical site infections related to Brucella species and discuss the infection control implications. Human brucellosis has the potential to cause surgical site infections and it should be in the differential diagnosis of any patient with a relevant exposure history presenting with a febrile illness and musculoskeletal findings.

Abstract
Human brucellosis is most commonly diagnosed by serology based on agglutination of fixed Brucella abortus as antigen. Nucleic acid amplification techniques have not proven capable of reproducibly and sensitively demonstrating the presence of Brucella DNA in clinical specimens. We sought to optimize a monoclonal antibody-based assay to detect Brucella melitensis lipopolysaccharide in blood by conjugating B. melitensis LPS to keyhole limpet hemocyanin, an immunogenic protein carrier to maximize IgG affinity of monoclonal antibodies. A panel of specific of monoclonal antibodies was obtained that recognized both B. melitensis and B. abortus lipopolysaccharide epitopes. An antigen capture assay was developed that detected B. melitensis in the blood of experimentally infected mice and, in a pilot study, in naturally infected Peruvian subjects. As a proof of principle, a majority (7/10) of the patients with positive blood cultures had B. melitensis lipopolysaccharide detected in the initial blood specimen obtained. One of 10 patients with relapsed brucellosis and negative blood culture had a positive serum antigen test. No seronegative/blood culture negative patients had a positive serum antigen test. Analysis of the pair of monoclonal antibodies (2D1, 2E8) used in the capture ELISA for potential cross-reactivity in the detection of lipopolysaccharides of E. coli O157:H7 and Yersinia enterocolitica O9 showed specificity for Brucella lipopolysaccharide. This new approach to develop antigen-detection monoclonal antibodies against a T cell-independent polysaccharide antigen based on immunogenic protein conjugation may lead to the production of improved rapid point-of-care-deployable assays for the diagnosis of brucellosis and other infectious diseases.

Abstract
We describe here a case of spondylodiscitis of brucellosis origin in one patient back from Turkey. Some weeks later, her mother, who had accompagnied her in Turkey also developped similar symptoms. A diagnosis of spondylodiscitis due to a contamination by Brucella melitensis was also proposed. Since the control of animal brucellosis in Europe, human cases are rarer. Sporadic cases still observed are mostly travellers back from aerea where animal brucellosis remains endemic. Seroprevalence of a second case of brucellosis among family members of a patient with brucellosis is significantly more elevated than in the general population. This justifies early detection among family members presenting with any medical symptom, in order to avoid chronicity. Early detection among asymptomatic family members is not clearly justified.

Abstract
Brucellosis, in particular infections with Brucella abortus, Brucella melitensis or Brucella suis, remains a significant human health threat in many areas of the world. The persistence of pathogenic Brucella spp. in domestic livestock or free-ranging wildlife remains unresolved, despite decades of regulatory efforts worldwide. Although vaccination is probably the most economic control measure, administration of currently available vaccines alone is not sufficient for elimination of brucellosis in any host species. Complacency in brucellosis control programs usually results in failure, or at best, limited reductions in disease prevalence or incidence of human infections. New brucellosis vaccines with high efficacy and safety are needed that address the diversity in host species and can be more widely applied under field conditions. Development of safer and more efficacious vaccines alone, or combined with enhancements or increased emphasis on other regulatory program components, could have tremendous impact on reducing the worldwide prevalence of brucellosis and the associated zoonotic infections.

Abstract
In China, brucellosis is an endemic disease and the main sources of brucellosis in animals and humans are infected sheep, cattle and swine. Brucella melitensis (biovars 1 and 3) is the predominant species, associated with sporadic cases and outbreak in humans. Isolates of B. abortus, primarily biovars 1 and 3, and B. suis biovars 1 and 3 are also associated with sporadic human brucellosis. In this study, the genetic profiles of B. melitensis and B. abortus isolates from humans and animals were analyzed and compared by multi-locus variable-number tandem-repeat analysis (MLVA). Among the B. melitensis isolates, the majority (74/82) belonged to MLVA8 genotype 42, clustering in the 'East Mediterranean' group. Two B. melitensis biovar 1 genotype 47 isolates, belonging to the 'Americas' group, were recovered; both were from the Himalayan blue sheep (Pseudois nayaur, a wild animal). The majority of B. abortus isolates (51/70) were biovar 3, genotype 36. Ten B. suis biovar 1 field isolates, including seven outbreak isolates recovered from a cattle farm in Inner Mongolia, were genetically indistinguishable from the vaccine strain S2, based on MLVA cluster analysis. MLVA analysis provided important information for epidemiological trace-back. To the best of our knowledge, this is the first report to associate Brucella cross-infection with the vaccine strain S2 based on molecular comparison of recovered isolates to the vaccine strain. MLVA typing could be an essential assay to improve brucellosis surveillance and control programs.

Abstract
A rapid and simple method for quantitative monitoring of Brucella melitensis using electrochemical impedance spectroscopy (EIS) is reported for the first time. The label-free immunosensors were fabricated by immobilizing Brucella melitensis antibody on the surface of gold nanoparticle-modified screen-printed carbon electrodes (GNP-SPCEs). Cyclic voltammetry (CV) and EIS were used to characterize the Brucella melitensis antigen interaction on the surface of GNP-SPCEs with antibody. A general electronic equivalent model of an electrochemical cell was introduced for interpretation of the impedance components of the system. The results showed that the change in electron-transfer resistance (Rct) was significantly different due to the binding of Brucella melitensis cells. A linear relationship between the Rct variation and logarithmic value of the cell concentration was found from 4 × 104 to 4 × 106 CFU/mL in pure culture. The label-free impedance biosensor was able to detect as low as 1 × 104 and 4 × 105 CFU/mL of Brucella melitensis in pure culture and milk samples, respectively, in less than 1.5 h. Moreover, a good selectivity versus Escherichia coli O157:H7 and Staphylococcus aureus cells was obtained for our developed immunosensor demonstrating its specificity towards only Brucella melitensis.

Abstract
Brucellosis is a zoonosis caused by ingestion of unpasteurized milk or other dairy products from infected animals or through close contact with their secretions. Human-to-human transmission, which is rare, has been reported in association with blood transfusion, bone marrow transplantation, transplacental or perinatal exposure, and breastfeeding. In the neonatal period, congenital brucellosis, which is an extremely rare condition, can lead to serious clinical consequences with a high morbidity and mortality rate. The case presented here is a premature baby born at 25 weeks' gestation to a mother suffering from severe oligohydramnios, premature rupture of membranes and untreated acute brucellosis. The baby had severe respiratory distress and radiological findings compatible with pulmonary infection. The blood cultures of the baby and the mother were positive for Brucella melitensis, supporting the diagnosis of brucellosis with presumed transplacental transmission.

Abstract
Brucellosis is a public health problem in most countries in the Mediterranean. Involvement of the central nervous system is seen in 4-13% of patients with brucellosis. A 13-year-old girl was admitted because of gait disturbance, diplopia, and dizziness. Her complaints began about 1.5 years ago. The second symptomatic episode repeated about three months ago and the third two months ago. In total, attacks repeated 3 times over 1.5 years. The magnetic resonance imaging (MRI) and the clinical features mimicked multiple sclerosis. The patient was given pulse steroid treatments. After steroid treatment, her gait disturbance and diplopia improved over the short term. Following positive developments, her symptoms recurred. The tests were repeated; the MRI showed increasingly high signal abnormalities, and Brucella melitensis was grown in cerebrospinal fluid. The patient was started on an oral combination of rifampin, doxycycline, and ciprofloxacin. MRI findings improved markedly after nine months of treatment. Although neurobrucellosis is associated rarely with demyelination in adults, this finding has not been reported previously in children or adolescents. Additionally, this case is the first in terms of involvement of the corpus callosum in neurobrucellosis. In this article, we present an unusual case of neurobrucellosis.

Abstract
The incidence of human brucellosis in Kyrgyzstan has been increasing in the last years and was identified as a priority disease needing most urgent control measures in the livestock population. The latest species identification of Brucella isolates in Kyrgyzstan was carried out in the 1960s and investigated the circulation of Brucella abortus, B. melitensis, B. ovis, and B. suis. However, supporting data and documentation of that experience are lacking. Therefore, typing of Brucella spp. and identification of the most important host species are necessary for the understanding of the main transmission routes and to adopt an effective brucellosis control policy in Kyrgyzstan. Overall, 17 B. melitensis strains from aborted fetuses of sheep and cattle isolated in the province of Naryn were studied. All strains were susceptible to trimethoprim-sulfamethoxazole, gentamicin, rifampin, ofloxacin, streptomycin, doxycycline, and ciprofloxacin. Multilocus variable number tandem repeat analysis showed low genetic diversity. Kyrgyz strains seem to be genetically associated with the Eastern Mediterranean group of the Brucella global phylogeny. We identified and confirmed transmission of B. melitensis to cattle and a close genetic relationship between B. melitensis strains isolated from sheep sharing the same pasture. Brucellosis is a bacterial disease causing abortion in cattle, sheep, and goats. It is transmissible to humans by direct transmission and the consumption of untreated milk. Brucellosis has become more and more frequent in Kyrgyzstan in the last decades, and its control has been made a priority. Knowing the bacterial strain circulating is important for the understanding of the transmission and the selection of interventions. The latest identification of Brucella in Kyrgyzstan dates from the 1960s. We report the molecular characterization 17 strains identified as Brucella melitensis from Naryn oblast. Strains were mainly isolated from sheep but also from cattle. All strains were susceptible to a series of antibiotics. We hence identified and confirmed transmission of B. melitensis among sheep which is likely the most important host species. We found close genetic relationship between B. melitensis strains isolated from cattle sharing the same pasture with sheep. Our results support the strategy of pursuing a mass vaccination of livestock in Kyrgyzstan. Further research is needed to identify the most important circulating strains in humans.

Abstract
A case of human brucellosis was diagnosed in France in January 2012. The investigation demonstrated that the case had been contaminated by raw milk cheese from a neighbouring dairy farm. As France has been officially free of bovine brucellosis since 2005, veterinary investigations are being conducted to determine the origin of the infection and avoid its spread among other herds. Hypotheses about the source of this infection are discussed.
