Abstract

Neospora caninum-associated abortion was diagnosed in a 7-mo gestational age beef cow fetus from Andorra. The fetus had a multifocal necrotizing encephalitis and nonpurulent multifocal myocarditis. The diagnosis was confirmed by demonstration of N. caninum DNA by polymerase chain reaction and tachyzoites by specific staining with N. caninum polyclonal antibodies in the fetal brain. The dam of the aborted fetus had serum N. caninum antibodies at the time of abortion but not 2 mo before abortion took place. This is the first report of N. caninum abortion in Andorra and the first confirmed N. caninum abortion in an acutely infected cow.

摘要

在一头来自安道尔、妊娠7个月的肉牛胎儿中诊断出与犬新孢子虫相关的流产。该胎儿患有多灶性坏死性脑炎和非化脓性多灶性心肌炎。通过聚合酶链反应检测到胎儿大脑中的犬新孢子虫DNA，并使用犬新孢子虫多克隆抗体进行特异性染色检测到速殖子，从而确诊。流产胎儿的母牛在流产时血清中有犬新孢子虫抗体，但在流产前2个月时没有。这是安道尔首次关于犬新孢子虫流产的报告，也是首例在急性感染母牛中确诊的犬新孢子虫流产病例。
