Rabbits (Oryctolagus cuniculus) are frequently reared for meat production in China. The aim of this study was to assess the seroprevalence of Toxoplasma gondii and Encephalitozoon cuniculi, and risk factors of infection in domestic rabbits raised in Henan province, central China. 1,213 serum samples of domestic rabbits were collected and tested for anti-T. gondii and anti-E. cuniculi antibodies using a modified agglutination test (MAT) and an enzyme-linked immunosorbent assay (ELISA), respectively. The serum positive rates of T. gondii and E. cuniculi were 128/1,213 (10.55%) and 235/1,213 (19.37%), respectively. Co-infection of T. gondii and E. cuniculi was demonstrated in 84 specimens; 44 rabbits were seropositive for T. gondii alone, while 151 rabbits were seropositive for E. cuniculi alone. The main risk factors simultaneously associated with T. gondii and E. cuniculi infection were the age of the rabbit, the type of food, and the rabbit rearing system. Serum positive rates of T. gondii and E. cuniculi among domestic rabbits were high, indicating the possibility of public health issues.
Résumé
Les lapins (Oryctolagus cuniculus) sont fréquemment élevés pour la production de viande en Chine. Le but de l’étude était de déterminer la séroprévalence de Toxoplasma gondii et d’Encephalitozoon cuniculi ainsi que les facteurs de risque d’infection chez les lapins domestiques élevés dans la province du Henan, en Chine centrale. 1 213 échantillons de sérum de lapins domestiques ont été collectés et testés pour les anticorps anti-T. gondii et anti-E. cuniculi en utilisant un test d’agglutination modifié (MAT) et un dosage immuno-enzymatique (ELISA), respectivement. Les taux sériques positifs de T. gondii et E. cuniculi étaient de 128/1 213 (10,55%) et de 235/1 213 (19,37%), respectivement. La co-infection par T. gondii et E. cuniculi a été démontrée chez 84 spécimens ; 44 lapins étaient séropositifs pour T. gondii seul, alors que 151 lapins étaient séropositifs pour E. cuniculi seul. Les principaux facteurs de risque associés simultanément à l’infection par T. gondii et E. cuniculi étaient l’âge du lapin, le type d’aliment et le système d’élevage du lapin. Les taux sériques positifs de T. gondii et d’E. cuniculi chez les lapins domestiques étaient élevés, ce qui indique la possibilité de problèmes de santé publique.
