SOROPREVALÊNCIA DE ANTICORPOS ANTI-Neospora caninum E ANTI-Leptospira interrogans EM DUAS PROPRIEDADES DE VACAS LEITEIRAS COM RELATOS DE PREJUÍZOS REPRODUTIVOS NOMUNICÍPIO DE GOIANDIRA, GOIÁS

Abstract

The aim of this study was to determine the seroprevalence ofantibodies anti-Neospora caninum and anti-Leptospira interrogansin dairy cows from Goiandira, Goiás State, Brazil. Serum samplesof 53 dairy cows from two herds were assayed for anti-N. caninumantibodies using an indirect immunofluorescent antibody test (IFAT)and microscopic-agglutination technique (MAT) for L. interrogansagglutinins. Sera reacting at dilutions ≥ 1:50 and ≥ 1:100 wereconsidered positive for N. caninum and L. interrogans antibodiesrespectively. It was found that 35.9% (14 cows) of the samplesfrom Farm 1 and 64.3% (9 cows) from Farm 2 were positive forN. caninum. For L. interrogans, 87.2% (34 cows) from Farm 1 and64.3% (9 cows) from Farm 2 were positive. The serovars foundedwere: wolffi (21.74%); hardjo (18.11%); bratislava (14.49%);australis (12.32%); tarassovi (12.32%); icterohaemorrhagiae(7.25%); sentot (5.80%), grippotyphosa (5.07%); patoc (2.17%);cynoptero (0.72%). According to the results, it was possible toconclude that neosporosis and leptospirosis are endemic in dairycows and may also be a significant animal and human healthproblem in Goiandira, GO, Brazil.
