Brucellosis is an important bacterial zoonosis responsible for considerable economic losses in livestock and health-related burden worldwide. The objective of this study was to determine the seroprevalence of brucellosis in communal and smallholder cattle farming in four districts of the North West province of South Africa (Dr Ruth Segomotsi Mompati, Ngaka Modiri Molema, Bojanala platinum and Dr Kenneth Kaunda districts). Seven hundred and seventy blood samples from farmed animals (n = 378) and abattoir-slaughtered animals (n = 392) were collected. In addition, milk samples (n = 22) were collected from lactating farmed cows. Rose Bengal test (RBT), complement fixation test (CFT) and milk ring test (MRT) were used to detect antibodies against Brucella species. The RBT showed a seroprevalence of 2% at 95% confidence interval (CI: 1.35–3.35), CFT confirmed an overall seroprevalence of 1.95% (95% CI: 1.14–3.12) for all four districts sampled. Although the seroprevalence of brucellosis was found to be low, the possibility of undetected cases of the disease could not be ruled out. Overall, the findings of this study confirmed that brucellosis is endemic in the surveyed areas of the North West province of South Africa. Contribution: The outcome of this study will contribute to the National Brucellosis Project organised by the Department of Agriculture, Land Reform and Rural Development (2016–2026) to assist in the effective implementation of the disease control measures with a view to prevent further outbreaks in the country’s cattle population.

Simple Summary: The presented manuscript provides the first data about the important zoonotic disease, brucellosis, in the population of wild boars on the territory of Serbia. Brucellosis is an important disease of animals, both domestic and wild, and humans, and is of exceptional importance. Recently, the disease has re-emerged in some countries and is a threat to public health. The infection was never investigated before in the population of wild boars in Serbia, although the reported infections in domestic pigs indicate the possible pathogen transmission from wild to domestic pigs. Applied serology assays provided Brucella seroprevalences in wild boars, while a wealth of statistics delivered important data. The obtained results confirm the presence of the infection in the population of wild boars in Serbia and open new chapters for the future investigations of brucellosis in wild boars in Serbia. Brucellosis is one of the most important bacterial zoonotic diseases worldwide, characterized in domestic animals by long-term reproductive disorders. As known, wild boars (Sus scrofa) are natural hosts for Brucella suis biovar 2, in which the infection passes in inapparent form, increasing the pathogen transmission risk to domestic pigs, other domestic animals and humans. So far, no studies regarding brucellosis in wild boars in Serbia have been published. During the hunting season 2020/2021, 480 sera of wild boars living in Serbia were collected and tested for the presence of anti-Brucella antibodies. For the serological survey, the Rose Bengal Test (RBT) and competitive enzyme-linked immunosorbent assay (c-ELISA) were used. Of the 480 sera, 45 sera tested positive, indicating the acquired Brucella seroprevalence in wild boars of 9.4%. The greatest numbers of Brucella seropositive animals were detected in the eastern parts of the country and in one of the central districts, i.e., Pomoravski, Branicevski, Borski and Juznobanatski. This study provides the first data regarding brucellosis in the wild boar population in Serbia, revealing the seroprevalence of Brucella, thus indicating that wild boars as natural hosts and/or vectors of Brucella likely present a risk for the infection of other animals.

Introduction: Human brucellosis is one of the most common zoonosis infections, with an important impact on the health and economy worldwide. This study aimed to update and provide epidemiological information on this infection and evaluate Rose Bengal Test, which is used as an essential diagnostic test for brucellosis in Erbil. Methodology: A total of 325 participants seeking care and reporting fever at Rizgary Teaching Hospital were enrolled. Blood samples were tested for Brucella spp. antibodies using Rose Bengal Test and blood culture followed by species identification. A questionnaire was administered to detect the risk factors. Results: The prevalence of probable and confirmed brucellosis was 12.3% (95% CI 9.2-16.3) and 9.5% (95% CI 6.8-13.2) respectively. The majority of cases were in the age group of 18-39 years. Brucellosis was significantly associated with raw milk consumption (OR = 10.3 95% CI 5-22.4) and contact with livestock (OR = 11.5 95% CI 5.6-23.9). Brucella melitensis (58.1%) and Brucella abortus (41.9%) are the dominant species in the area. The sensitivity, specificity, positive predictive value, and negative predictive value of the Rose Bengal Test in comparison to the blood culture were 100%, 96.9%, 77.5 %, and 100% respectively. Conclusions: Brucellosis is a significant cause of fever in Erbil and could be diagnosed by the Rose Bengal Test taking into account the compatibility of clinical features with the positive result. The vaccination of livestock and boiling or pasteurization of milk are essential procedures to reduce the frequency of human brucellosis. [ABSTRACT FROM AUTHOR]

Background and purpose: Brucellosis is one of the most prevalent infectious diseases in Iran that is shared between humans and animals and is caused by species of Brucella. The present study aims to determine the seroprevalence of brucellosis in people suspicious of brucellosis referred to the Health Care Center of Gonbad during 2009-11. Materials and methods: In this cross-sectional study, blood specimen was taken from patients and their serum was separated. Rose Bengal antigens, antigens of Brucella abortus strain 19 and 2ME buffer were prepared and Rose Bengal test was performed on all sera. In positive cases, to determine antibody titr, tube Wright and 2ME were performed (1.80 ≤ were considered positive). Results: Of 318, 42 (13.2%) were positive, among whom were 20 women (47.6%) and 22 males (52.4%). Having conducted the Rose Bengal test 46 (14.5%), tube Wright (1.80 ≤) 42 (13.2%) and 2ME (1.80 ≤) 34 cases (7.10%) were proved to be positive. Conclusion: The rate of Seroprevalence in the study area is indicative of high incidence of the disease. It seems a large number of communities due to lifestyle (close contact with pets and consumption of unpasteurized dairy products) are exposed to pollution. Because of occupational nature of the disease in the region, vaccination, patient care, overseeing the slaughter of livestock and the use of pasteurized dairy products are recommended.
