ANTICORPOS CONTRA AGENTES BACTERIANOS E VIRAIS EM SUÍNOS DE AGRICULTURA FAMILIAR DO MUNICÍPIO DE MONTE NEGRO, RO

ANTIBODIES AGAINST BACTERIAL AND VIRAL AGENTS IN SWINE FROM FAMILY-RUN FARMS IN MONTE NEGRO COUNTY, STATE OF RONDONIA, BRAZIL. Sera from swine from family-employed farms in Monte Negro County, state of Rondonia, Brazil, were evaluated against bacterial and viral agents. Brucellosis was evaluated by Rose-Bengal agglutination (RBA), standard tube agglutination (STA), and mercaptoethanol (ME); and leptospirosis by microscopic agglutination test (MAT) against 24 leptospira serovars. Anti-porcine parvovirus antibodies were tested by haemmaglutination inhibition assay, and ELISA technique was used for detection of antibodies against classical swine fever virus and Aujeszky disease virus. Only 1 (0.9%) from 104 tested sera reacted by RBA, and no samples reacted in STA and ME. Leptospira spp. antibodies were detected in 29 (32.9%) of 88 tested sera and the most frequent serovars detected were Castellonis, Bratislava and Canicola. Antibodies against porcine parvovirus were detected in 7.7% (8/104) of the sera. None of the examined samples reacted to classical swine fever virus or Aujeszky disease virus.
