Serum samples from 11,842 commercial pigs killed in 1983-1984 throughout the United States were tested for anti-Toxoplasma gondii antibodies by the agglutination test in dilutions of 1:25, 1:50, and 1:500. Anti-T. gondii antibodies were found in 23.9% of pigs. At dilutions of 1:25, 1:50, and 1:500, 13.5%, 6.9%, and 3.5% were serologically positive, respectively. The prevalence of anti-T. gondii antibodies was higher in breeder pigs (42%) than in market pigs (23%). These results indicate that anti-T. gondii antibodies are widespread in the national swine herd.
1983年至1984年期间在美国各地宰杀的11842头商品猪的血清样本,通过凝集试验在1:25、1:50和1:500的稀释度下检测抗刚地弓形虫抗体。在23.9%的猪中发现了抗刚地弓形虫抗体。在1:25、1:50和1:500的稀释度下,血清学阳性率分别为13.5%、6.9%和3.5%。种猪中抗刚地弓形虫抗体的流行率(42%)高于市场猪(23%)。这些结果表明抗刚地弓形虫抗体在全国猪群中广泛存在。
