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.
1995年5月至9月期间，在越南南部采集了200份奶牛血清样本和200份肉用水牛血清样本。采用酶联免疫吸附试验和间接荧光抗体试验分析血清中抗犬新孢子虫抗体，采用直接凝集试验分析血清中抗弓形虫抗体。在5.5%的奶牛血清和1.5%的水牛血清中检测到显著水平的犬新孢子虫抗体。发现10.5%的奶牛血清和3%的水牛血清含有弓形虫抗体。两份奶牛血清同时含有弓形虫和犬新孢子虫抗体。本报告首次报道了水牛感染犬新孢子虫的血清学证据。
