Abstract

A serological survey for antibody activity to Neospora caninum was carried out in Aguascalientes, a state in the central part of Mexico. One-hundred and eighty-seven serum samples from 13 dairy herds were tested by the ELISA test. The herd prevalence was 100% and the overall prevalence was 59% (n=110). Seventy-six of 97 seropositive cows had previous records of abortion. There was a statistically significant difference between the groups (P<0.05). However, the odds ratio was 1.4, suggesting an association between abortion and seropositivity. Neosporosis in dairy cattle appears to be widespread in Mexico, warranting more epidemiological studies to determine the distribution of the causative protozoan.

摘要

在墨西哥中部的阿瓜斯卡连特斯州开展了一项针对犬新孢子虫抗体活性的血清学调查。采用酶联免疫吸附测定（ELISA）试验检测了来自13个奶牛场的187份血清样本。牛群流行率为100%，总体流行率为59%（n = 110）。97头血清阳性奶牛中有76头曾有过流产记录。两组之间存在统计学显著差异（P<0.05）。然而，比值比为1.4，表明流产与血清阳性之间存在关联。奶牛的新孢子虫病在墨西哥似乎广泛存在，需要开展更多流行病学研究以确定致病原生动物的分布情况。
