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.
Résumé
Il n’y a actuellement aucune information concernant les infections par Sarcocystis neurona et Neospora hughesi chez les ânes au Mexique. Dans cet article, nous avons déterminé la présence d’anticorps contre S. neurona et N. hughesi chez les ânes dans l’État de Durango au nord du Mexique. Des échantillons de sérum de 239 ânes domestiques (Equus asinus) ont été testés pour les anticorps de S. neurona et N. hughesi à l’aide d’immunoessais enzymatiques faits maison; six (2.5 %) des 239 ânes ont été testés séropositifs pour S. neurona. La séroprévalence de l’infection par S. neurona était comparable chez les ânes, quels que soient leur origine, leur état de santé ou leur sexe. L’analyse multivariée a montré que la séropositivité à S. neurona était associée à l’âge (OR = 2.95 ; IC à 95 % : 1.11-7.82 ; p = 0.02). Les anticorps contre N. hughesi ont été trouvés chez 2 (0.8 %) des 239 ânes. Les deux ânes positifs étaient des femelles de 3 à 6 ans en bonne santé. Ceci est la première preuve d’infections à S. neurona et N. hughesi chez les ânes au Mexique.
