Serum samples from 545 woodchucks Marmota monax from 22 counties in Pennsylvania were examined for antibodies to Toxoplasma gondii by the modified direct agglutination test. Fifty-one woodchucks (9.4%) had antibodies to T. gondii, with 10% at dilutions of 1:25, 2% at dilutions of 1:50, and 4% at dilutions of 1:500. This is the first report of T. gondii antibodies in woodchucks.
采用改良直接凝集试验，检测了来自宾夕法尼亚州22个县的545只土拨鼠（Marmota monax）的血清样本，以检测抗刚地弓形虫抗体。51只土拨鼠（9.4%）有抗刚地弓形虫抗体，其中10%在1:25稀释度时有抗体，2%在1:50稀释度时有抗体，4%在1:500稀释度时有抗体。这是关于土拨鼠体内刚地弓形虫抗体的首次报告。
