AimThis cross-sectional study was conducted from April to July 2012 in Khartoum state, Sudan, to determine the seroprevalence of brucellosis in goats and to investigate potential risk factors associated with this disease.Materials and MethodsA total of 307 serum samples were collected from both sexes of goats in four different localities and were subjected to testing for brucellosis using rose bengal plate test (RBPT), serum agglutination test (SAT), and competitive enzyme-linked immunosorbent assay (cELISA).ResultsThe overall seroprevalence was 11.4% (n=35) with a 95% confidence interval (CI) ranging from 7.80 to 15.0. Out of these 35 RBPT-positive samples, the positivity of 18 and 17 were confirmed by SAT and cELISA, respectively. A significant statistical variation was observed between brucellosis seroprevalences in goats purchased from local animal markets and goats that were raised at the farm. Conversely, such significant variations were not observed among the categories of other risk factors with seroprevalences ranging from 3.0% (95% CI between 0.40 and 7.20) to 16.3% (95% CI between 10.4 and 22.3). Location (χ2=9.33, df=3, p=0.02), breed (χ2=3.52, df=1, p=0.05), herd size (χ2=6.59, df=2, p=0.03), and herd expansion (χ2=5.39, df=1, p=0.02) were associated with RBPT-positive status for brucella in the two-tailed Chi-square test. In addition, Sharq an-Nil locality and goats raised at the farm had increased odds of being RBPT positive.ConclusionBrucellosis was detected in goats in all surveyed localities. An effort should be made to educate goat owners/herders about brucellosis as well as about the importance of vaccination.

“…Since majority of butchermen are males who has high risk of acquiring brucellosis, it can be the reasons for the high prevalence of the disease. This is similar to findings by other studies [32, 33]. However, none of these have establish the risk that shepherds have towards brucellosis in Tanzania despite the fact that they are at the starting point of the livestock value chain.…”

“…The difference can be attributed to differences in geographical locations and the use of a single but highly sensitive test (Rapid agglutination test) in the previous study. In other parts of Africa, brucellosis studies among high risk occupations in Ghana and Nigeria in slaughterhouses found seroprevalences of 9.6% [25] and 24.1% [11] while a study in Sudan found varying prevalences of 9.5%, 15.3%, 24.4% and 26.5% among veterinarians, meat inspectors, abattoir workers and animal handlers, respectively [26]. The findings in Ghana, Nigeria and Sudan were higher than those found in this study in all occupational groups.…”

14Background 15 Brucellosis is an infectious zoonotic disease that affects humans, livestock and wildlife. 16 Methods 17 A cross-sectional study was conducted in Mbeya region between November 2015 and January 18 2016 to investigate the seroprevalence of human brucellosis and identify associated risk factors 19 among individuals in risky occupations in Mbeya Region. A total of 425 humans from six 20 occupational categories were serially tested for Brucella antibodies using the Rose Bengal Plate 2 21Test (RBPT) and competitive Enzyme Linked Immunosorbent Assay (c-ELISA), for screening 22 and confirmation, respectively. A questionnaire survey was administered to participants collect 23 epidemiological data. 24 Results 25The overall seroprevalence among the high risk occupational individuals was 1.41% (95% CI: 26 0.01-0.03). Seroprevalence among the different occupations were as follows: shepherds 1.33% 27 (95% CI: 0.14-0.22); butcher men 5.26% (95% CI: 0.10-0.17) and abattoir workers 1.08% 28 (95% CI: 0.39-0.49). Seroprevalence was noted to vary according to occupation type, milk 29 consumption behaviour, age and sex. Butcher men recorded the highest seroprevalence (5.0%) 30 while individuals who consumed unboiled milk had a higher seroprevalence (1.56%) compared 31 to those who drunk boiled milk. High seropositivity (2.25%) was observed among the age 32 group of 1-10 years while male individuals had a higher seroprevalence (1.41%) than females 33 (0%). Butcher men were at higher risk of exposure compared to other professions. 34 Conclusion 35Our findings show the presence of brucellosis in occupationally exposed individuals in Mbeya 36 region. There is need to sensitize the exposed individuals in order to reduce the risk of acquiring 37 Brucella infections from animals and animal products This also calls for public health 38 awareness about the disease, and implementation of control measures that will prevent further 39 spread of brucellosis within and outside the study area.. 40 41

“…[15] A recent study carried out in Sudan reported a seroprevalence of 9.5%, 15.3%, 24.4% and 26.5% in veterinarians, meat inspectors, abattoir workers and animal handlers respectively. [16] A seroprevalence of 40% among high-risk groups has also reported in Libya. [17] In West Africa, Nigeria confirmed endemicity of bovine brucellosis among slaughtered cattle using the ELISA, showing that it is an occupational hazard to workers directly involved in cattle meat processing.…”

Brucellosis remains neglected in many countries despite its public health importance. In developing countries such as Ghana, there remains paucity of data particularly among high-risk populations such as slaughterhouse workers. The aim of this study was to determine the prevalence of Brucella infection and risk factors for its transmission among people working in and around slaughterhouses. A cross-sectional study was carried out with 220 participants selected through a stratified sampling method. Participants were interviewed about their knowledge on Brucella and their occupational activities using a structured questionnaire. Collected serum samples were analyzed for anti-Brucella Immunoglobulin M (IgM) and Immunoglobulin G (IgG) antibodies using the enzyme-linked immunosorbent assay method. Data was analyzed using uni-and multivariate logistic regression models. From 220 participants, anti-Brucella IgM-and IgG antibodies were detected in 4 (1.8%) and 21 (9.6%), respectively. 9.3% of the participants with animal contact at work (5/54) and 11.5% of those working in meat processing (17/148) have heard about Brucella and its transmission mode. Most of the anti-Brucella IgG seropositive individuals (17/21) were working in the meat processing category (OR 2.2; 95% CI 0.6-7.9; p = .22). Multivariate analysis showed that job duration was significantly associated with seropositivity to Brucella IgG (OR 1.31; 95% CI 0.9-1.8, p-value .03). The findings demonstrate recent and past Brucella infections among workers of the Kumasi abattoir with a high risk for less educated meat processing staff. Thus, intensive educational programmes on Brucella designed for workers with high risks and improving workplace protection policy are recommended.
