This study was carried out to evaluate the intercurrence of brucellosis and enzootic leucosis in buffaloes in extensive production system by establishing the prevalence of reagent buffaloes for specific diagnostic tests. We analyzed 232 animals serologically by the technique of double immunodiffusion in agarose gel (AGID) for diagnostic of leucosis and the tampon acidified antigen (TAA) test, followed by confirmatory tests of 2-mercaptoethanol (2-ME) and slow serum agglutination (SSA) in tubes for diagnostic of brucellosis. The prevalence of buffaloes that were positive for leucosis and brucellosis tests were 4.21% (10/232) and 5.18%(12/232) respectively. The results of this investigation indicated that the diseases occur in the population studied, however, with low prevalence and without depending on the occurrence of both.
