title: Prevalence of antibodies to Neospora caninum and Toxoplasma gondii in cattle and water buffaloes in southern Vietnam.
abstract: Serum samples from 200 dairy cattle and 200 beef water buffaloes were collected in southern Vietnam during May to September 1995. The sera were analysed for antibodies to Neospora caninum by an enzyme-linked immunosorbent assay and the indirect fluorescent antibody test, and for antibodies to Toxoplasma gondii by the direct agglutination test. Significant levels of N. caninum antibodies were detected in 5.5% of the cattle sera and in 1.5% of the water buffalo sera. 10.5% of the cattle sera and 3% of the water buffalo sera were found to contain T. gondii antibodies. Two of the cattle sera had both T. gondii and N. caninum antibodies. The present communication is the first to report serological evidence of N. caninum infection in the water buffalo.
