Prevalence of brucellosis in the human, livestock and wildlife interface areas of Serengeti National Park, Tanzania

A cross-sectional survey conducted between 2005 and 2006 in agropastoral communities near Serengeti National Park, Tanzania, revealed a 5.6% seroprevalence of brucellosis in cattle, with no human cases detected. The study used the Rose Bengal Plate Test (RBPT) and Competitive Enzyme Linked-immunosorbent Assay (c-ELISA) to analyze sera from 82 humans and 413 livestock across four villages at the domestic-wildlife interface. Seropositivity was restricted to cattle, with herd-level prevalence ranging from 25% to 66.7%. Age and sex were not statistically associated with infection in cattle (P = 0.63; 95% CI = 0.03, 0.8 for age and P = 0.33; 95% CI = 0.6, 3.7 for sex). The findings highlight the need for further investigation to identify circulating Brucella strains and inform control interventions in domestic animals.
