Seroprevalence of brucellosis in mithuns (Bos frontalis) in India.

Studies conducted on the seroprevalence of brucellosis in 98 mithuns maintained at the National Research Centre on Mithun, Nagaland, India revealed that the number of animals found positive for brucellosis in avidin-biotin enzyme-linked-immunosorbent assay, standard tube-agglutination test and Rose-Bengal plate test were 34, 20 and 11%, respectively. Highest prevalence of brucellosis was observed in the Mizoram mithun strain. The relative sensitivity and specificity of the standard tube-agglutination test were 61 and 100%, respectively; the corresponding values of the Rose-Bengal plate test were 33 and 100%, respectively.
