【 摘 要 】

The aim of this study was to determine the occurrence of anti-Neospora caninum antibodies in serum samples collected from 260 bovine fetuses, between July 2007 and March 2008, in an abattoir in the municipality of Santa Maria, Rio Grande do Sul, Brazil. An indirect fluorescent antibody test was used to detect anti-N. caninum immunoglobulins G (IgG) and M (IgM), using a cut-off of 1:25. Considering IgG or IgM detection, 15% (39/260) of the samples tested were found positive. Among the positive samples, 38 (97.4%) were positive for IgG and 6 (15.4%) for IgM. However 5 (12.8%) of it were positive for both IgG and IgM. These results are in agreement with the proven ability of N. caninum to fetal infection. IgM testing was few relevant to detect N. caninum transplacental infection through fetal bovine serum analisys.Index
