The heartworm Dirofilaria immitis is the causative agent of cardiopulmonary dirofilariosis in dogs and cats, and also infects humans. However, there has been no study on dirofilariasis in dogs in central China. From March 2015 to February 2016, sera from 1176 randomly selected household dogs from Henan province, central China were examined for D. immitis antigen using the Canine Heartworm Antigen Test Kit. The overall seroprevalence of D. immitis in dogs in Henan province was 13% (155/1176). The prevalence was significantly higher in older dogs and dogs kept outdoors, compared to the younger ones and those sheltered indoors. No significant difference of prevalence was observed between sexes. The results suggest that the risk of exposure to D. immitis in dogs is high in Henan, and prophylaxis against the parasite is advisable to decrease the incidence of canine dirofilariosis in this region.
Résumé
Le Nématode Dirofilaria immitis est l’agent causal de la dirofilariose cardiopulmonaire chez les chiens et les chats, et infecte aussi les humains. Cependant, il n’y a pas de rapport sur la dirofilariose chez les chiens dans le centre de la Chine. De mars 2015 à février 2016, les sérums de 1176 chiens domestiques choisis au hasard dans la province du Henan, en Chine centrale, ont été examinés pour l’antigène de D. immitis en utilisant le kit Canine Heartworm Antigen Test. La séroprévalence globale de D. immitis chez le chien dans la province du Henan était de 13 % (155/1176). La prévalence était significativement plus élevée chez les chiens âgés et les chiens abrités en plein air, par rapport aux plus jeunes et ceux abrités à l’intérieur. Aucune différence significative de prévalence n’a été observée entre les sexes. Les résultats suggèrent que le risque d’exposition à D. immitis chez les chiens est élevé dans le Henan, et il est conseillé d’utiliser la prophylaxie contre le parasite pour diminuer l’incidence de la dirofilariose canine dans cette région.
