Sandakly N, El Koubayati G, Ayoub A, Haddad F. Brucellosis complicated by piriformis myositis and sacroiliitis: A case report and a review of the literature. Heliyon 2024; 10:e28617. [PMID: 38590840 PMCID: PMC11000000 DOI: 10.1016/j.heliyon.2024.e28617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 03/11/2024] [Accepted: 03/21/2024] [Indexed: 04/10/2024] Open
Abstract
Brucellosis remains an endemic zoonosis in the Middle East, particularly in Lebanon, owing to the high consumption of raw meat and unpasteurized cheese. In this report, we present the case of a twenty-one-year-old girl who was diagnosed with brucellosis during the investigation of persistent fever and night sweats that was confirmed by an elevated Brucella agglutination titer at 1/160 for Brucella melitensis species, and an indirect Coombs at 1/1280. Unfortunately, owing to non-adherence to the antibiotic regimen prescribed, her condition progressed, resulting in piriformis myositis with sacroiliitis, an unusual complication of brucellosis. Resolution occurred following a treatment regimen comprising intravenous gentamycin 5mg/kg daily for two weeks along with rifampin 300mg TID, and doxycycline 100mg BID for 12 weeks. Furthermore, we conducted a literature review, which revealed the diagnostic and imaging criteria for this uncommon complication to be still unclear, as well as the lack of universally approved guidelines for its treatment. Brucella - myositis should be suspected when patients present with fever and back pain.

[PMID: 38452046 PMCID: PMC10950246 DOI: 10.1371/journal.pntd.0012030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 03/19/2024] [Accepted: 02/27/2024] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND Brucellosis, a widely spread zoonotic disease, poses significant diagnostic challenges due to its non-specific symptoms and underreporting. Timely and accurate diagnosis is crucial for effective patient management and public health control. However, a comprehensive comparative review of available diagnostic tests is lacking. METHODOLOGY/PRINCIPAL FINDINGS This systematic review addressed the following question: 'What is the accuracy of the available tests to confirm human brucellosis?' Two independent reviewers examined articles published up to January 2023. The review included original studies reporting symptomatic patients with brucellosis suspicion, through any index test, with sensitivity and/or specificity as outcomes. As exclusion criteria were considered: sample size smaller than 10 patients, studies focusing on complicated brucellosis, and those lacking essential information about index or comparator tests. Sensitivity and specificity were assessed, with consideration for the index test, and 'culture' and 'culture and standard tube agglutination test (SAT)' were used as reference standards. Bias assessment and certainty of evidence were carried out using the QUADAS-2 and GRADE tools, respectively. A total of 38 studies reporting diagnostic test performance for human brucellosis were included. However, the evidence available is limited, and significant variability was observed among studies. Regarding the reference test, culture and/or SAT are deemed more appropriate than culture alone. Rose Bengal, IgG/IgM ELISA, and PCR exhibited equally high performances, indicating superior overall diagnostic accuracy, with very low certainty of the evidence. CONCLUSIONS/SIGNIFICANCE This systematic review underscores the potential of the Rose Bengal test, IgG/IgM ELISA, and PCR as promising diagnostic tools for brucellosis. However, the successful implementation and recommendations for their use should consider the local context and available resources. The findings highlight the pressing need for standardization, improved reporting, and ongoing advancements in test development to enhance the accuracy and accessibility of brucellosis diagnosis.

Geo-temporal patterns to design cost-effective interventions for zoonotic diseases -the case of brucellosis in the country of Georgia. Front Vet Sci 2023; 10:1270505. [PMID: 38179332 PMCID: PMC10765567 DOI: 10.3389/fvets.2023.1270505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 11/27/2023] [Indexed: 01/06/2024] Open
Abstract
Introduction Control of zoonosis can benefit from geo-referenced procedures. Focusing on brucellosis, here the ability of two methods to distinguish disease dissemination patterns and promote cost-effective interventions was compared. Method Geographical data on bovine, ovine and human brucellosis reported in the country of Georgia between 2014 and 2019 were investigated with (i) the Hot Spot (HS) analysis and (ii) a bio-geographical (BG) alternative. Results More than one fourth of all sites reported cases affecting two or more species. While ruminant cases displayed different patterns over time, most human cases described similar geo-temporal features, which were associated with the route used by migrant shepherds. Other human cases showed heterogeneous patterns. The BG approach identified small areas with a case density twice as high as the HS method. The BG method also identified, in 2018, a 2.6-2.99 higher case density in zoonotic (human and non-human) sites than in non-zoonotic sites (which only reported cases affecting a single species) -a finding that, if corroborated, could support cost-effective policy-making. Discussion Three dissemination hypotheses were supported by the data: (i) human cases induced by sheep-related contacts; (ii) human cases probably mediated by contaminated milk or meat; and (iii) cattle and sheep that infected one another. This proof-of-concept provided a preliminary validation for a method that may support cost-effective interventions oriented to control zoonoses. To expand these findings, additional studies on zoonosis-related decision-making are recommended.

Abstract
Leptospirosis is a significant worldwide zoonotic infectious disease that infects a wide range of animals and humans. Leptospira will colonize the animal's urinary and reproductive systems and be excreted with urine, potentially causing a wide range of infections. Dogs are an essential host for Leptospira, and epidemiological investigation studies of leptospirosis must be conducted to clarify the prevalence of leptospirosis and to reduce the risk of transmission to humans. This study aimed to investigate the seroepidemiology of leptospiral infection in dogs from Changchun, China, using Microscopic Agglutination Test (MAT). A total of 1053 canine blood samples were collected and tested by MAT. The positive rate of MAT was approximately 19.1%. The main prevalent Leptospira serogroups were L. Icterohaemorrhagiae (8.1%), L. Canicola (7.6%), L. Australis (5.3%), L. Ballum (4.7%) and L. Pyrogenes (4.2%). No statistically significant difference among different varieties, sexes and sampling seasons (p > 0.05), except the age (p < 0.05). The seropositive rate was much higher in adult and aged dogs than in juvenile dogs. Our results showed the seroprevalence and the prevalent serogroup of Canine leptospirosis in Changchun, China.

Abstract
Brucellosis is a rising veterinary and human health problem in India. It may manifest with a varied multisystem clinical presentation. In our case patient was of 72 years male with a complaint of abdominal pain for 2 months following COVID-19 infection. He was a known case of CAD (coronary artery disease) post PTCA status, on regular follow up & treatment. Patient had post COVID pulmonary fibrosis. When the patient admitted in our hospital with above mentioned complaints, necessary investigations along with blood culture by automated method was sent and patient was started on empirical doxycycline along with other symptomatic treatment. As the patient was not very sick and was reluctant to stay in hospital during the COVID-19 situation, he was discharged on request with a treatment and follow up plan. Blood culture was found to be positive for Brucella melitensis. When we got the blood culture report the patient was contacted telephonically and started Rifampicin along with Doxycycline for 6 weeks.

Abstract
Brucellosis is a significant zoonotic disease and is endemic in several regions of the world. This study is aimed to determine the nationwide spatial distribution, seroprevalence, and risk factors for Brucella infections in Jordan. Serum samples of 938 individuals from 11 governorates were tested for Brucella spp. antibodies using Rose Bengal and Brucellacapt® tests. A validated questionnaire was used to collect demographic, animal ownership, and food consumption data. The seroprevalence of Brucella infection in Jordan’s population was 6.7% (95% CI, 5.2–8.5%). The multivariate model showed that location of residence, consuming raw milk/milk products, and owning small ruminants (goat and/or sheep) were significantly associated with seropositivity after controlling for age and gender. Individuals living in the northern Badia region had 8.82 greater odds (95% CI, 4.56–17.03) of seropositivity than individuals living in the Middle region of the country. Individuals who reported consumption of raw milk/milk products had 3.7 higher odds (95% CI, 2.01–6. 81) of seropositivity compared with individuals not consuming raw milk/milk products. In addition, individuals who own small ruminants (goat and/or sheep) had 2.14 higher odds (95% CI, 1.11–4.12) of seropositivity compared with individuals who do not own small ruminants. The identified geographic hotspots and small ruminants’ ownership, risk of raw milk products highlight the need for tailored training, education campaigns, and resources for controlling brucellosis in Jordan.

Abstract
OBJECTIVES In 2017, the incidence of human brucellosis in Tunisia was 9.8 per 100,000 population. In the Douz district, 2 cases were reported in March 2018. Prior to that date, the last indigenous cases to be reported in Douz had been in 2015. This study aimed to identify the source of this new contamination and recommend control interventions. METHODS This case-control study included residents of Douz who presented with clinical symptoms of brucellosis and had a subsequent Wright test antibody titer ≥ 1/160. The controls were neighbors of the infected cases who had a negative Rose Bengal test. Univariate and multivariate analyses were performed to estimate the odds ratios of risk factors. Goats belonging to the cases and controls were actively screened. RESULTS Twenty-five infected cases and 52 uninfected controls were enrolled. All infected cases had consumed goat milk and 92% had purchased it from the same breeder. Consumption of goat milk from this breeder (adjusted odds ratio [aOR], 30.78; 95% confidence interval [CI], 6.47 to 235.91) and overall consumption of raw goat milk (aOR, 14.84; 95% CI, 2.04 to 310.44) were independent risk factors for brucellosis. The breeder had 18 goats, 5 of which were smuggled from a neighboring country. Three of those goats were diagnosed with brucellosis. CONCLUSIONS Consumption of raw milk from smuggled sick goats was the main risk factor in this outbreak. The sick goats were slaughtered and an education campaign was conducted. Vaccination, control of cross-border animal movements, and control of goat milk sales must be strengthened to prevent the spread of brucellosis in southwestern Tunisia.

Abstract
Brucellosis is one of the most important and widespread bacterial zoonotic diseases worldwide, and it is transmitted to humans from various sources, including direct contact with infected animals and the ingestion of contaminated products, including unpasteurized milk. There are only a few epidemiological studies on said disease in humans in Western Santa Catarina, a region instantiated by agriculture. Thus, the objective of this study was to characterize the epidemiological aspects of human brucellosis reported in Western Santa Catarina from 2013 to 2018. The data were provided by the Epidemiological Surveillance Board (Diretoria de Vigilancia Epidemiologica). The frequency of the disease in humans and the epidemiological profile of confirmed human cases were evaluated. Cases that were screened positive and those that were confirmed and submitted to the therapeutic protocol were analyzed. During the study period, 3,671 people were tested, of which 12.34% were screened positive (453/ 3,671) and 3.40% were confirmed (125/3,671). The year with the highest number of people testing positive was 2015 (123 cases), and 2018 was the year with the highest number of confirmed cases (39 cases). Confirmed cases predominated in males (48.8%), self-declared white (22.4%), aged 20-59 years old (60%), with incomplete primary education (22.4%), of rural origin (59.2%), with occupational contact with cattle (64.8%), engaged in professions directly linked to agricultural and livestock activities (55.5%), and who reported consumption of unpasteurized dairy products (59.2%). No seasonal variation was observed in case numbers. The results demonstrated that brucellosis is an endemic disease in Western Santa Catarina.

Abstract
BACKGROUND Brucellosis is a disease of domestic and wild animals commonly caused by Brucella species and can be transmitted to humans (zoonosis). Susceptibility to Brucellosis in Humans depends on immune status, routes of infection, size of the inoculums, and to some extent, the species of Brucella. Globally more than 500,000 new cases are reported each year. In sub-Saharan Africa, Brucellosis prevalence is unclear and poorly understood with varying reports from country to country, geographical regions as well as animal factors. METHODS Facility-based unmatched case-control study was conducted on 167 patients with human brucellosis and 332 controls from February 27/2019 to May 20/2019 in AYU primary hospital, North Showa Zone, Ethiopia. descriptive statistics such as frequency and percentages were used to describe the profile of case and control and analytical statistics such as bivariate and multivariate logistic regression analysis was performed to identify the determinants of human brucellosis. RESULT A total of 499 participants were included with a response rate of 99.60%. The mean age of participants was 45.46 years with a standard deviation (SD) of ±12.96 years. Human brucellosis had a statistically significant association with raw milk consumptions (AOR 5.75[95%CI 1.97-16.76]), slaughtering of animals at home(AOR 14.81[95%CI 3.63-60.38]), having contact with animal manure(AOR 2.87 [CI 1.08-7.62]), having contact with aborted cattle's fetus (AOR 3.01[95%CI 1.34-9.13]) and knowledge about brucellosis(AOR 0.29 [95%CI 0.08-0.83]. CONCLUSION Generally in this study knowledge about Human Brucellosis, contact with animal manures, practicing animal slaughtering at home, having contact with animal ruminants, and consuming raw milk were identified as determinants for human brucellosis infection.

Abstract
Background: Brucellosis is the most common zoonotic disease in Iran, imposing a significant financial burden on the healthcare system. The diversity of non-specific clinical manifestations of this disease can lead to misdiagnosis or delayed diagnosis. Therefore, it is important to pay attention to other aspects of this disease. Objectives: This study aimed to determine the epidemiology, clinical and laboratory manifestations, and outcomes of brucellosis. Methods: In this cross-sectional study, brucellosis patients, admitted to three hospitals, affiliated to Shahid Beheshti University of Medical Sciences (Tehran, Iran) from April 2015 to September 2020, were examined. The patients' medical records were reviewed for epidemiological, clinical, and laboratory findings. The outcomes of the disease were evaluated by phone calls. Results: Of the 104 patients included in this study, 53.8% were male, and 46.2% were female. The mean age of the patients was 43.07 ± 18.521 years. Unpasteurized dairy consumption and contact with livestock were reported in 60.6 and 27.9% of the patients, respectively. Also, 23.1% of the patients had high-risk occupations. The most common symptoms included fever (80.8%), chills (58.7%), backache (55.8%), and sweating (51%). The most common complication was osteoarticular involvement (21.2%), followed by neurobrucellosis (6.7%). Elevated alkaline phosphatase (89.7%), anemia (67.3%), increased C-reactive protein (57.7%), and increased erythrocyte sedimentation rate (48.1%) were common laboratory findings. The rates of improvement, treatment failure, and relapse were 86.9, 9.1, and 4%, respectively. There was no significant relationship between the rate of improvement and the antibiotic regimen. However, the most common cause of treatment failure was the patient’s poor compliance with treatment. Conclusions: The diversity of non-specific clinical manifestations of brucellosis is a diagnostic challenge. Therefore, physicians must request laboratory tests to evaluate brucellosis after taking a precise epidemiological and clinical history of suspected cases.

Abstract
INTRODUCTION Brucellosis, the most common zoonosis globally, is considered a major public health problem. OBJECTIVE A retrospective study was carried out over 21 years (1998-2018) to determine the epidemiological features of human brucellosis in the province of El-Oued (south-eastern Algeria). RESULTS 1,832 confirmed cases of human brucellosis were reported during the study period, with an average incidence rate of around 12.26 cases per 100,000 inhabitants. The annual distribution of the incidence was characterized by an increasing trend and a strong fluctuation ; its values ranged between 2.27 and 24.96 per 100,000 inhabitants. The monthly distribution showed that the highest incidence rates were recorded from mid-February to July, with a peak of 2.74 cases per 100,000 inhabitants in April.Human brucellosis has affected all municipalities. The highest incidence rate was observed in border municipalities such as Ben Guecha and Oum Tiour (89.76 and 66.14 per inhabitants, respectively).The incidence in the male population was higher than that of the female at 14.63 versus 9.83 per 100,000 inhabitants, respectively, noting that it increases with age. Individuals over 65 years are the most at risk, with an incidence rate of 22.32 per 100,000 inhabitants. CONCLUSION Along with strengthening preventive measures in the population, eliminating brucellosis in animals is the most effective method to protect humans against infection.

Seroprevalence and Associated Risk Factors of Canine Leptospira and Brucella Species Infection in West Shewa Zone, Central Ethiopia. VETERINARY MEDICINE-RESEARCH AND REPORTS 2021; 12:33-42. [PMID: 33665154 PMCID: PMC7924131 DOI: 10.2147/vmrr.s297155] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/13/2020] [Accepted: 02/10/2021] [Indexed: 12/20/2022]
Abstract
Purpose Canine leptospirosis and brucellosis are significant zoonotic gram-negative bacterial diseases that affect humans and animal species. This study was aimed to estimate the seroprevalence and assess associated risk factors of canine Leptospira and Brucella species infections in Ambo, Bako, and Gojo Towns, West Shewa Zone, Ethiopia. Methods A total of 385 serum samples were collected from randomly selected dogs. Antibodies against Brucella and Leptospira species infection were tested using the Enzyme-Linked immunosorbent Assay technique (ELISA). A structured questionnaire survey was administered to each dog-owning household to gather information on potential risk factors. The association between independent and outcome variables was analyzed using the Chi-square test followed by univariable, and multivariable logistic regression analyses. Results The overall seroprevalence of Brucella and Leptospira species infections were found to be 15.06% (95% confidence interval (ci): 11.64–19.04%) and 4.16% (95% ci: 2.39–6.67%), respectively. Multivariable logistic regression analysis showed that the town was the significant risk factor of Brucella species infection seropositivity. Accordingly, dogs found in Gojo ((odds ratio (OR)): 17.72 CI: 1.17–117.54, p=0.036) and Bako (OR: 7.99, 95% CI: 0.96–66.37), p=0.054 towns were more at risk to be infected with Brucella species than dogs living in Ambo. Conclusion The seroprevalence of Leptospira and Brucella species infections in dogs of the West Shewa Zone was high and moderate, respectively, suggesting the possible transmission of the disease between dogs and other animals. These infections might be an under-recognized threat to public health and animal welfare. Further research on the identification of the serovars of Leptospira and biotypes of Brucella circulating in dogs is encouraged. Finally, knowledge of the comprehensive epidemiology of these diseases is an invaluable input for veterinarians, healthcare professionals, and policy-makers to avoid or manage canine leptospirosis and brucellosis.

TROPICAL DISEASES TRAVEL MEDICINE AND VACCINES 2021; 7:5. [PMID: 33531081 PMCID: PMC7851939 DOI: 10.1186/s40794-021-00130-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Accepted: 01/25/2021] [Indexed: 12/02/2022]
Abstract
Background Brucellosis is a zoonotic disease caused by Brucella spp., namely B. melitensis and B. abortus in humans. Culturing is the gold standard method for diagnosis; however, because Brucella is a slow-growing bacterium, which may delay diagnosis, other faster methods, such as serology, are used. Studies on the correlation between Brucella antibody titers and clinical outcomes are limited. Therefore, this study assessed such correlation and evaluated the correlation between baseline serological results with culture positivity and clinical picture. Methods Patients tested positive for Brucella antibodies at baseline and diagnosed with brucellosis between January 2008 and December 2018 were included. Collected data included clinical outcomes, baseline culture positivity (growth in culture), arthralgia, baseline and end of therapy (EOT) temperature, white blood cell count, C-reactive protein level, and erythrocyte sedimentation rate. Results Of 695 patients tested for Brucella antibodies, only 94 had positive baseline serology and diagnosed with acute brucellosis, among whom 63 had EOT serology. No significant correlations were found between EOT antibody titers of both Brucella spp. and clinical cure, mortality, length of stay, and duration of therapy. Additionally, no correlations were found between baseline serology and culture positivity, arthralgia, temperature, and other lab values. Conclusion Brucella serology does not correlate with clinical outcomes at EOT nor with culture positivity at baseline. Therefore, healthcare providers are advised to consider the whole clinical picture of a brucellosis patient without relying solely on serological results during follow up and not replace culturing with serology testing alone at the time of diagnosis.

Abstract
Neurobrucellosis is an uncommon and dangerous complication of brucellosis. Meningitis is the most common presentation of neurobrucellosis, but it may present in a wide range of clinical manifestations such as myelitis, brain abscess, radiculopathy, and cranial nerve involvement. It tends to present insidiously with symptoms appearing gradually. Acute presentation of neurobrucellosis is very uncommon. Here, we report a case of a female child who presented with an acute onset of ataxia and slurred speech with positive cerebrospinal fluid (CSF) and neuroimaging findings for neurobrucellosis. In endemic countries such as Saudi Arabia, neurobrucellosis should be considered as a differential diagnosis for patients presenting with unexplained neurological symptoms.

Abstract
Background Brucellosis, an endemic disease in Saudi Arabia, has an infection rate of 70 per 100,000 people, with a varying morbidity rate in different parts of the country. The aim of this study was to assess the epidemiological and clinical features, laboratory findings, treatment modalities, complications, and outcomes in children with brucellosis. Materials and methods The medical records of 153 patients attending King Abdullah Specialist Children’s Hospital in Riyadh, Saudi Arabia, from January 2015 to January 2019 were reviewed retrospectively. Demographic data, laboratory test results, serum agglutination test titer, and the results of the blood cultures were obtained. The diagnosis of brucellosis was based on compatible signs and symptoms with a positive serology titer of ≥1:160 or a blood culture positive for Brucella species. Results The majority of the sample (69.6%, n=107) were males, with a mean age of 7.75 ± 3.28 years. Ingestion of unpasteurized camel dairy products was the most frequent transmission risk factor. The most prevalent presenting symptoms were constitutional and musculoskeletal symptoms. Six patients (3.9%) had complicated brucellosis, with neurobrucellosis diagnosed in three cases. Hospitalization for brucellosis was required in 15% of the patients. The majority (99.35%, n=152) of the patients had a serum agglutination test (SAT) titer of ≥1:160. A blood culture was positive in 52 (34%) of the 111 patients tested. The most frequently prescribed regimen was rifampicin + co-trimoxazole in 81 (52.9%) patients. Relapse occurred in a small proportion (4.6%, n=7), and the majority (95.4%, n=146) had a complete remission. Conclusions The main route of transmission was the ingestion of unpasteurized dairy products. Brucellosis had a wide range of clinical presentation, involving multiple organ systems. Neurobrucellosis was the most frequent complication. The SAT was the most useful and reliable test for the diagnosis of brucellosis. Most patients were successfully treated with rifampicin and co-trimoxazole for six weeks.

Abstract
Introduction Brucellosis is a zoonotic disease that can involve different organs and tissues. Fever, fatigue, lymphadenopathy, hepatosplenomegaly, cytopenia, and arthritis are the usual modes of presentation. Gastrointestinal manifestations of human brucellosis are common but documented ileal involvement is extremely rare. Case Description A 68-year-old female presented with a history of 10 days of intense temporal migraine, photophobia, and phonophobia with partial response to paracetamol. The patient referred night sweats, anorexia, and colicky abdominal pain after her meals for the past 4 months followed by diarrhea. She denied nausea, vomiting, hypersensitivity of the scalp, blurry vision, melena, or rectal bleeding. She denied travelling or contact with animals. Physical examination revealed fever (38.3°C) and splenomegaly. Laboratory workup revealed Hb 7.8 g/dL, leukopenia (3.47 × 109/L), C-reactive protein 5.94 mg/dL, and erythrocyte sedimentation rate 23 mm/h. Abdominal ultrasound showed hepatic steatosis and mild homogeneous splenomegaly. Chest radiography was normal. Lumbar puncture; transcranial, carotid, and temporal arteries Doppler, and head computed tomography (CT) did not show any significant changes. Abdominal CT showed diffuse thickening of the ileum and some mildly swollen locoregional lymph nodes. Fecal calprotectin was not elevated. Blood cultures and serologies were positive for Brucella (positive Rose-Bengal test, ELISA IgM-positive, IgG-negative anti-brucella antibody serology and positive Huddleson reaction - titer 1:320). The patient was started on rifampicin 600 mg/day and doxycycline 100 mg q. 12 h for 10 weeks with good clinical and analytical response. Upper and lower gastrointestinal endoscopy were normal, although the last was done already under antibiotic treatment. Discussion Although gastrointestinal manifestations of brucellosis are quite common, ileitis is thought to be extremely rare. In countries where brucellosis is endemic, doctors must consider this diagnosis when faced with patients with systemic symptoms and diarrhea or abdominal pain. Early recognition of brucellosis and institution of appropriate therapy usually leads to a good recovery without complications.

Abstract
Purpose To describe the incidence trend, demographic and clinical characteristics, treatment and prognosis, epidemiological history and risk factors of human brucellosis in Huludao, China. Patients and Methods A total of 1887 brucellosis patients were reported in Huludao, China from January, 2014 to December, 2018 and the case questionnaires from 1149 patients were collected from Huludao Municipal Center for Disease Control and Prevention. Demographic characteristics of the patients and the information relating to the patients' clinical manifestations, diagnosis, treatment and prognosis were collected and analyzed. Results The number of annually reported brucellosis patients has dropped from 711 to 187 during the study period, with the incidence decreased from 27.31/100,000 in 2014 to 7.15/100,000 in 2018. A total of 1149 individual data were collected, with a mean age of 49.59±13.14 years and 75.7% were male. Patients aged more than 60 years were more likely to have arthralgia/myalgia than the other age groups, and patients who had an enlarged spleen in male were more than female (P<0.05). There were more acute brucellosis cases, less sub-acute and chronic brucellosis cases in the ethnic minority (83.6%, 5.5% and 11.0%, respectively) than that in the Han nationality (64.7%, 22.2% and 13.0%, respectively, P<0.05). For antibiotic therapy, "Doxycycline plus rifampicin or streptomycin" was the most commonly used drug combination. Sheep/goat was the main contacted animal and feeding/grazing was the most frequent transmission route; no personal protective measures were the major risk factor. Conclusion The incidence of human brucellosis is still high in Huludao, China, and this is mostly associated with contacting with domestic animals and barely taking protective measures. The most common clinical manifestations of brucellosis patients in Huludao were fatigue, hyperhidrosis, fever, and arthralgia/myalgia, the most common route of exposure was feeding and grazing, and the major species of livestock was sheep/goat. The most commonly adopted treatment option was antibiotic therapy, and most patients responded well to treatment. The integrality and accuracy of the notifiable epidemiological case questionnaire needs to be improved in order to provide more factual and objective information for both the physicians and policy-makers.

Abstract
Zoonotic diseases are endemic in the country of Georgia. Using the non-linear canonical correlation (NCC) method, the aim of this study was to examine the relationship between thirteen epidemiological risk factors and seropositivity to five zoonotic infections (anthrax, Q fever, tularemia, leptospirosis, and Crimean-Congo hemorrhagic fever [CCHF]) among Georgian military recruits during 2014-2016. According to this multivariate statistical technique, which is suitable for the analysis of two or more sets of qualitative variables simultaneously, two canonical variables were identified. These variables accounted for 68% of the variation between the two sets of categorical variables ("risk factors" and "zoonotic infections"). For the first canonical variable, there was a relationship among CCHF (canonical loading, which is interpreted in the same way as the Pearson's correlation coefficient, [cl] = 0.715), tick bites (cl = 0.418) and slaughter of animals (cl = 0.351). As for the second canonical variable, Q fever (cl = -0.604) and leptospirosis (cl = -0.486) were related to rodents inside and outside home (cl = -0.346) and sweeping in or around home (cl = -0.317). The NCC method allows researchers to obtain additional insights into the complex relationship between epidemiological risk factors and multiple zoonotic infections.

Abstract
Our study assesses the influence of illness duration before establishing the diagnosis of brucellosis and initiating therapy on patients' main clinical characteristics and outcome in an endemic area. The medical files of 297 patients with brucellosis were retrospectively analysed. They were divided into four groups according to illness duration before initiating therapy: <10 days; 11-30 days; 31-90 days; and >90 days. There were significant differences in the occurrences of fever (P = 0.019), focal forms (P = 0.026), spondylitis (P = 0.034) and therapeutic failures (P = 0.006) between the groups. Duration of >30 days before treatment initiation is responsible for more serious clinical presentation and outcome, whereas illness duration of >90 days further worsens the clinical progression in human brucellosis.

Abstract
Background: Brucellosis is a serious disease affecting many individuals in the world and in Iran. The aim of this study was to investigate the epidemiological and clinical features of patients diagnosed with brucellosis in Kohgilouyeh and Boyerahmad province, southwest of Iran. Methods: This retrospective descriptive-analytic study included all individuals diagnosed with brucellosis during 2009–2015. The clinical and epidemiological information were gathered from recorded data available in the health center of Kohgilouyeh and Boyerahmad province, the southwest of Iran. Results: The total number of patients diagnosed with brucellosis during the study period was 658, of whom, 339 (51.5%) were males. A total of 541 (82.2%) patients resided in rural and tribal areas, and the others lived in urban regions. The mean age of diagnosis was 39.59 ± 17.28 years and the most prevalent age groups were 31–50 (277, 42.1%) and 11–30 (178, 27.1%)-year olds. The most affected groups were housekeeper women (229, 34.8%) and ranchers (152, 23.1%). The relationship between jobs and disease was significant (P < 0.001). Transmission through either suspected dairy products (582, 88.4%) or close contact with infected livestock (537, 81.6%) comprised the most common routes of brucellosis dissemination. The clinical presentation was acute in the majority (581, 88.3%) of the patients. The highest titer for both wright and Coombs wright tests was 1:320. The most frequently administrated drugs were doxycycline and streptomycin (183, 27.8%). The most commonly observed clinical symptom was bone pain (477, 72.5%). Arthritis (12, 1.8%) comprised the most frequent drug-associated complication. Either relapse or treatment failure was recorded collectively in four (0.6%) patients. Conclusions: Due to the prevalence of the disease in the nomadic areas, timely detection and control of the disease is essential. Furthermore, livestock vaccination along with educating farmers and physicians about brucellosis can be helpful.

Abstract
Human cases of brucellosis in the United States are primarily limited to imported infections or reservoirs. We describe a brucellosis outbreak involving 8 patients treated at a single hospital in the United States. Standardized precautionary microbiology processes and coordinated collaboration among hospital departments and local health departments assisted in optimally managing this disease at our institution.
