Sero-prevalence Of Brucellosis In Smallholder Dairy, Agropastoral, Pastoral, Beef Ranch And Wildlife Animals In Tanzania

摘要

collected from one ranch which had a history of abortion and also from 90 wildlife animals that were darted for various purposes. The results of sero-conversion revealed that cattle, small ruminants and wildlife animals were exposed to Brucella infection, with the sero-prevalence of the infection being 6.2%, 6.5% and 13% respectively. Pastoral farming system had significantly higher Brucella antibodies (P<0.01) compared to small holder dairy and agro-pastoral farming systems. The sero-prevalence in the small holder dairy animals was significantly lower (p<0.01) than that of agro-pastoral and pastoral animals whereas that of pastoral animals was significantly higher (P<0.01) than that of agro-pastoral animals. Pastoral animals were 3 more likely of being exposed to Brucella infection compared to animals in the agro-pastoral farming systems.rnThis study therefore, shows that Brucella antibodies was present in both domestic animals and wildlife thus calling for formulation of strategic control measures in order to reduce associated reproductive wastage and the public health risks.
