E-mail: adivaldofonseca@yahoo.com The prevalence of brucellosis in buffaloes was evaluated by the Buffered Acidified Plate Antigen (BAPA) in 5.163 water buffaloes from Maranhao state, Para state and Marajo Island, Brazil. The detection of buffaloes positive for brucellosis by BAPA was 7.37% in Marajo Island, 8.45% in Para state and 29.86% in Maranhao state. The locations with the highest prevalences were Santa Cruz do Arari, in Marajo Island (12.50%); Ipixuna, in Para state (30.25%); and Santa Ines, in Maranhao state (34.76%). After the confirmatory test (Complement Fixation Test), only 7 animals remained positive in Marajo Island, and 22 remained positive in the state of Para. None of the 66 animals that reacted positively in the BAPA test in Maranhao reacted positively in the CF. The high prevalence of B. abortus that was observed in animals, especially in the state of Maranhao, is worrisome for the health system for the control and eradication of bovine brucellosis.
