Detecção de anticorpo anti-Brucella sp. e anti-Leptospira spp. em búfalos (Bubalus bubalis) abatidos em matadouro na cidade de Belém, Pará

Abstract

The present study aimed to detect the presence of buffalos serum reagents for Brucella sp. and Leptospira spp. Serum samples from 113 animals from Marajo Island, slaughtered at a slaughterhouse in the city of Belem, Para, were used, which were submitted to the Rapid Agglutination Test with buffered, acidified plate antigen (BAPA) and 2-Mercaptoethanol ( 2-ME) for the detection of antibodies against Brucella sp. and the Microscopic Agglutination Test (MAT) for the detection of agglutinins against Leptospira spp. From the 113 samples analyzed, 13.3% (15/113) were reagents for Brucella sp. antibodies in AAT and 6.1% (7/113) were confirmed in the 2-ME test. For Leptospira spp., 35.4% (40/113) of the buffalos were reactive with serovar Hardjo C.T.G., present in 75% (30/40) of the reactions. It was concluded that antibodies against the investigated agents were detected, demonstrating the need to make a more efficient sanitary control in the herd.
