Discipline: Veterinary Medicine



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 using immuno stimulating 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.
