Seroprevalence of Neospora caninum Antibodies in Selected Dairy Cattle Herds from Lagima and Quezon Provinces, Philippines

摘要

This study was conducted to determine the prevalence of antibodies to Neospora caninum in serum samples from different dairy cattle herds in Laguna and Quezon provinces with history of reproductive disorders such as abortion and repeat breeding usingimmunostimulating complex-enzyme-linked immunosorbent assay (iscom-ELISA). Nineteen (11%) out of 172 serum samples showed positivity to N. caninum. The seroprevalence of N. caninum in the five dairy herds varied from 0 to 21.7%. Although iscom-ELISA is not a definitive test, the result indicates the possible occurrence of the organism in the positive herds. Further studies, regular testing and continuous monitoring of N. caninum on herds especially with seropositive animals and its relation to reproductive problems are recommended.
