Abstract
A study was carried out to compare the prevalence of Brucella abortus between semi-intensive and extensive managed cattle in the North West Region of Cameroon. A total of 689 cattle were tested for Brucella antibodies using the competitive Enzyme-Linked Immunosorbent Assay. Overall prevalence of brucellosis was found to be 5.2% (n = 36). There was strong evidence that cows in the extensive system (6.5%; n=32) had a higher infection rate than those in the semi intensive system (2%; n=4; P<0.0001). Bovine overall brucellosis infection rates were higher in the dry season (67%) than the rainy season (33%), (P<0.05). Healthier cattle (78%; P=0.0009), older cattle (64%; P=0.0003) and cows (75%; P=0.0027) were more infected. The prevalence of Brucella in the White Fulani breed was less severe than in other breeds (P=0.0003). Acha had more infected animals than the rest of the region (P<0.0001). The results of this study confirm the endemicity of bovine brucellosis in the North West Region of Cameroon and a moderate seroprevalence rate in extensive cattle management systems in the study area. There is a need for eliminating positive reactors, implementing control measures and raising public awareness of zoonotic transmission of brucellosis, and on improvement of extensive cattle management systems.
