Levantamento sorológico de Mycobacterium avium subesp. paratuberculosis em bovinos leiteiros no estado do Espírito Santo / Serological survey of Mycobacterium avium subsp. paratuberculosis in dairy cattle in Espírito Santo state

ABSTRACT

The occurrence of antibodies to Mycobacterium avium subsp. paratuberculosis (MAP) was verified in dairy cattle from Espírito Santo state. A total of 1,450 serum samples were analyzed for antibodies anti-MAP, using ELISA. Dairy cattle, males and females, from four regions of Espírito Santo state were used. One hundred sixty-five (11.4 percent) samples were positive for anti-MAP, 33 (2.3 percent) were considered suspicious, and 1,252 (86.3 percent) were negative. In all regions, seropositive animals were found, indicating that the agent is spread by the State, posing a threat to the local dairy farming and neighboring states, as well as public health, since MAP can be involved with Crohn's disease in humans. This result presents the first serologic anti-MAP survey in dairy cattle of Espírito Santo State.
