Nineteen white-tailed deer (Odocoileus virginianus) from 5 counties in Alabama were examined for infection with Toxoplasma gondii. Twenty-gram samples of heart tissue were bioassayed in mice, serum was examined for T. gondii antibodies using the direct agglutination test, and sections of heart muscle were examined histologically for tissue cysts. Toxoplasma gondii was isolated from 4 of 19 (21%) white-tailed deer hearts. Antibody titers of greater than or equal to 1:50 were found in sera from 7 of 16 (44%) white-tailed deer. Histological examinations of tissue sections from white-tailed deer hearts were negative for T. gondii.
对来自阿拉巴马州5个县的19只白尾鹿（弗吉尼亚白尾鹿）进行了弓形虫感染检测。取20克心脏组织样本在小鼠体内进行生物测定，用直接凝集试验检测血清中的弓形虫抗体，并对心肌切片进行组织学检查以寻找组织囊肿。从19只白尾鹿的4只（21%）心脏中分离出了弓形虫。在16只白尾鹿的7只（44%）血清中发现抗体效价大于或等于1:50。白尾鹿心脏组织切片的组织学检查未发现弓形虫。
