Abstract

The aim of this study was to determine the seroprevalence of antibodies anti-Neospora caninum and anti-Leptospira interrogans in dairy cows from Goiandira, Goiás State, Brazil. Serum samples of 53 dairy cows from two herds were assayed for anti-N. caninum antibodies using an indirect immunofluorescent antibody test (IFAT) and microscopic-agglutination technique (MAT) for L. interrogans agglutinins. Sera reacting at dilutions ? 1:50 and ? 1:100 were considered positive for N. caninum and L. interrogans antibodies respectively. It was found that 35.9% (14 cows) of the samples from Farm 1 and 64.3% (9 cows) from Farm 2 were positive for N. caninum. For L. interrogans, 87.2% (34 cows) from Farm 1 and 64.3% (9 cows) from Farm 2 were positive. The serovars founded were: 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 to conclude that neosporosis and leptospirosis are endemic in dairy cows and may also be a significant animal and human health problem in Goiandira, GO, Brazil.
