Most reports of neosporosis associated with abortion in cattle are in dairy cattle and infected calves do not survive beyond 7 days of age. This paper reports neosporosis in a 4-week-old Hereford calf. The calf was full term and appeared clinically normal at birth. At 2 weeks of age, the calf had weakened and was unable to nurse unassisted. The calf was killed at 4 weeks because of paralysis. The primary lesions were in the brain and were associated with Neospora caninum tachyzoites. The diagnosis was confirmed by immunohistochemical staining with anti-Neospora rabbit serum.
大多数关于牛流产相关新孢子虫病的报告都来自奶牛,受感染的犊牛存活不超过7日龄。本文报告了一例4周龄赫里福德犊牛的新孢子虫病。该犊牛足月出生,出生时临床外观正常。2周龄时,犊牛身体变弱,无法自主吮乳。4周龄时,该犊牛因瘫痪而被处死。主要病变位于脑部,与犬新孢子虫速殖子有关。通过抗新孢子虫兔血清免疫组化染色确诊。
