There is currently no information regarding Sarcocystis neurona and Neospora hughesi infections in donkeys in Mexico. Here, we determined the presence of antibodies against S. neurona and N. hughesi in donkeys in the northern Mexican state of Durango. Serum samples of 239 domestic donkeys (Equus asinus) were assayed for S. neurona and N. hughesi antibodies using home-made enzyme-linked immunoassays; six (2.5%) of the 239 donkeys tested seropositive for S. neurona. The seroprevalence of S. neurona infection was comparable among donkeys regardless of their origin, health status, or sex. Multivariate analysis showed that seropositivity to S. neurona was associated with increased age (OR = 2.95; 95% CI: 1.11-7.82; p = 0.02). Antibodies to N. hughesi were found in two (0.8%) of the 239 donkeys. Both exposed donkeys were healthy, 3- and 6-year-old females. This is the first evidence of S. neurona and N. hughesi infections in donkeys in Mexico.
目前在墨西哥，尚无关于驴感染犬新孢子虫和休氏新孢子虫的相关信息。在此，我们确定了墨西哥北部杜兰戈州驴体内抗犬新孢子虫和抗休氏新孢子虫抗体的存在情况。使用自制的酶联免疫分析法对239头家驴（Equus asinus）的血清样本进行了犬新孢子虫和休氏新孢子虫抗体检测；239头驴中有6头（2.5%）犬新孢子虫检测呈血清阳性。无论驴的来源、健康状况或性别如何，犬新孢子虫感染的血清阳性率相当。多变量分析表明，犬新孢子虫血清阳性与年龄增长相关（比值比=2.95；95%置信区间：1.11 - 7.82；p = 0.02）。在239头驴中有2头（0.8%）检测到抗休氏新孢子虫抗体。这两头受感染的驴均健康，分别为3岁和6岁的雌性。这是墨西哥驴感染犬新孢子虫和休氏新孢子虫的首个证据。
