Sero-epidemiology of brucellosis in small ruminants in Plateau State, Nigeria
African journal of microbiology research
A sero-epidemiological study of brucellosis in small ruminants was carried out in Plateau state to determine the status of the disease. A total of 1347 serum samples from 851 goats and 496 sheep systematically collected from nine randomly selected Local Government Areas (LGA) of the state were tested for brucella antibodies using Rose Bengal plate test (RBPT) and serum agglutination test (SAT). The result revealed brucellosis prevalence of 14.5% in sheep and 16.1% in goats, respectively. The prevalence varied from one LGA to another and between sheep and goats in each LGA. In goats, the highest prevalence of 19.7% was recorded in Mangu LGA while the lowest (10.3%) was in Shendam LGA. In sheep, Quanpan LGA had the highest prevalence of 23.5% while Bassa LGA had the least prevalence of 6.3%. The prevalence in goats was higher compared to sheep but this was not statistically significant (p > 0.05). The widespread brucellosis seroprevalence in Plateau state is of great economic and public health significance. There is the need to embark on control and eradication of small ruminant brucellosis in Plateau state, Nigeria. Culling of affected small ruminants and maintenance of good hygienic practices will be useful methods of control at this point in time.
This study was designed to determine the sero-epidemiological status of small ruminant brucellosis in Bauchi state, Nigeria. A total of 739 small ruminants comprising of 324 and 415 sheep and goats respectively from the three Senatorial Zones of the State were used for this study. Blood samples were collected from small ruminants slaughtered in the abattoirs and flocks of sheep and goats in the study area. Rose Bengal Plate test (RBPT) was used to screen all the sera obtained from the animals and Competitive Enzyme Linked Immunosorbent Assay (cELISA) was used to confirm the RBPT positive sera. Out of 324 sheep sampled, 114 (35.2 %) and 77 (23.8 %) were positive for Brucella infection by RBPT and cELISA, respectively. Similarly, out of 415 goat sampled, 98 (23.6 %) and 56 (13.5 %) were positive by RBPT and cELISA respectively. In sheep, the highest prevalence of brucellosis using cELISA were found in Dass and Darazo LGAs with (37.2 %) and (20.0 %) being positive, respectively, while the lowest prevalence was found in Ningi and Gamawa LGAs with (16.0%) and (19.4 %) being positive, respectively. However, in goats, the highest prevalence of brucellosis using cELISA test were recorded in Katagum LGA (25.5 %) and Darazo LGA (22.6 %) while the lowest prevalence was in Gamawa LGA (3.5 %) and Ningi 4 samples (8.3 %) respectively. There was no statistically significant difference (P < 0.05) between brucellosis and sex of the small ruminants. It was concluded that brucellosis is endemic among small ruminants in Bauchi state, Nigeria. There is need to intensify campaigns on brucellosis and its implication on livestock production.

Introduction: In Niamey, Niger, interactions within the interface between animals, humans and the environment induce a potential risk of brucellosis transmission between animals and from animals to humans. Currently, little is known about the transmission of Brucella in this context. : 5,192 animals from 681 herds were included in the study. Serum samples and hygroma fluids were collected. A household survey enabled to identify the risk factors for transmission of brucellosis. The true adjusted herd-level prevalence of brucellosis ranged between 11.2% and 17.2% and the true adjusted animal-population level prevalence was 1.3% (95% CI: 0.9-1.8%) based on indirect ELISA test for Brucella antibodies. Animals aged of 1-4 years were found to be more susceptible than animals less than 1 year old (Odds ratio [OR] of 2.7; 95% CI: 1.43-5.28). For cattle, the odds of brucellosis seropositivity were higher in rural compared to the periurban areas (OR of 2.8; 95% CI: 1.48-5.17) whereas for small ruminants the risk of seropositivity appeared to be higher in urban compared to periurban areas (OR of 5.5; 95% CI: 1.48-20.38). At herd level, the risk of transmission was increased by transhumance (OR of 5.4; 95% CI: 2.84-10.41), the occurrence of abortions (OR of 3.0; 95% CI: 1.40-6.41), and for herds having more than 50 animals (OR of 11.0; 95% CI: 3.75-32.46). Brucella abortus biovar 3 was isolated from the hygromas.

Objective: To determine the current status of Brucella antibodies in sheep in Kaduna North Senatorial District of Kaduna State, Nigeria. Methods: A total of 579 serum samples were collected (114 rams and 465 ewes) and analysed using Rose Bengal plate test (RBPT), serum agglutination test with ethylene diamine tetraacetic acid (SAT-EDTA) and lateral flow assay (LFA). Results: The prevalence of Brucella antibodies was found to be 26.5%, 11.1% and 2.4% using RBPT, SAT-EDTA and LFA respectively. The prevalence was 22.8%, 7.9%, 1.8% and 27.5%, 12.7% and 3.0% for the males and females using RBPT, SAT-EDTA and LFA, respectively. The prevalence rate for animals of less than 1 year of age was 23.8%, 14.3% and 9.5% for RBPT, SAT-EDTA and LFA, respectively, the corresponding prevalence rate for animals within the age bracket of 1 to 3 years was 26.7%, 11.2% and 1.4%, using RBPT, SAT-EDTA and LFA, respectively. Seroprevalence for animals above 3 years old were 24.7%, 12.4% and 3.5%, respectively. Conclusions: It is evident that sheep in the study area are infected with Brucella spp., including Brucella melitensis in view of the LFA positivity. This is of public health significance.

Available reports on brucellosis in Nigeria are largely confined to cattle while it is believed that other ruminants like sheep and goats are equally exposed to the disease. To have an insight into the role of goats in the epidemiology of brucellosis in Nigeria, we conducted a cross-sectional study between June 2011 and May 2013 to determine the seroprevalence of brucellosis in goats in some selected states in Nigeria. Serum samples were collected from goats at different locations and tested for antibodies to Brucella spp using the Rose Bengal Test (RBT), samples positive by RBT were further subjected to Competitive Enzyme Linked Immunosorbent Assay (cELISA). Data collected to determine risk factors were also analysed using chi-square and logistics regression statistics. Out of a total of 2827 samples tested from the different states (Benue = 331; Borno =195; Oyo = 2155; Sokoto = 146), we recorded an overall seroprevalence of 2.83% (Benue = 17.30%; Borno = 2.05%; Oyo = 0.60% and Sok...

A cross-sectional study was conducted in Wukari, Taraba state, Nigeria, to determine the prevalence of Brucella antibodies and the risk factors associated with brucellosis in indigenous breeds of goats. A total of 386 goats were sampled from three political wards: Puje, Avyi, and Hospital: harvested sera samples were subjected to Rose Bengal Plate Test (RBPT). GraphPad Prism version 7.03 for Windows (GraphPad Software, La Jolla California, USA) was used to analyse the association between seroprevalence of brucellosis and age, sex, breed, location, and management system by using Chi square and Fisher’s exact test as appropriate. Brucellosis was detected in all three wards: Puje; 15%, Avyi; 6.6%, and Hospital; 7.6%. A prevalence rate of 2.8%, 8%, 18.7%, and 1% was recorded for <20-month, 22-35-month, 36-45-month, and ≥46-55-month age categories, respectively (P < 0.05). Only 9.5% was observed for male animals while 9.8% was observed for female animals with no statistical differe...

Objective: Brucellosis is a bacterial zoonotic disease caused by members of the genus Brucella. It causes economic loss and ill health among animals and humans. This study was conducted to determine the prevalence of brucellosis in cattle particularly in White Fulani breed of cattle in Kwara State, Nigeria. Materials and methods: A total of 120 blood samples were collected randomly from the cattle in Kwara State of Nigeria. Sera were separated from the blood samples. The serum was used for the identification of antibodies against Brucella present in it. Three screening tests namely Bovine Brucella Antibody Test (BBAT; ImmunoComb R), Rose Bengal Plate Test (RBPT) and Serum Agglutination Test (SAT) were used for the identification purpose. Results: Based on BBAT, 13.3% (n=16/120) cattle were positive for brucellosis. Similary, 14.2% (n=17/120) and 3.3% (n=4/120 cattle were found to be positive for RBPT and SAT, respectively. The affected cattle were mainly of White Fulani breed with few cross-bred. Conclusion: Results of this study indicates that brucella antibody is circulating in cattle examined in the study area. This calls for urgent public health intervention and routine screening of other domestic animals as well.

Brucellosis is an ancient and one of the world’s most widespread zoonotic diseases affecting public health and animal production. A cross-sectional study using simple random sampling was conducted between May and December, 2016 in Maigana and Birnin Gwari Agro-ecological zones of Kaduna State to determine the sero-prevalence of brucellosis in sheep. In addition the risk factors associated with sero-positivity in sheep were also assessed. A total of 400 sera samples comprised of 141 from males and 259 from females sheep were collected and screened for the presence of Brucella antibodies using Rose Bengal Plate test (RBPT) and competitive enzyme linked immunosorbent assay (cELISA). Sera analysis revealed that, 16.5% and 10.8% were seropositive to Brucella infection by RBPT and cELISA, respectively. There was statistically significant association between sex of the sheep and seropositivity to Brucella infection using RBPT (P < 0.05). Meanwhile, no statistically significant associati...
