Abstract

HERNANDEZ-CAMACHO, Norma et al. Dirofilaria immitis (Spirurida: Onchocercidae) filariae in gray fox (Urocyon cinereoargenteus) in Mexico. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.1, pp.252-254. ISSN 2007-8706.  https://doi.org/10.7550/rmb.45845.

The study of the parasite fauna of Mexican wild canids is relevant because of their potential as sentinel species for ecosystem health. The following study was conducted in a suburban area in Santiago de Querétaro, Mexico. We registered Dirofilaria immitis filariae in a gray fox male Urocyon cinereoargenteus blood sample on November of 2013. Further analysis showed there were not adult heartworms infecting the gray fox indicating that the animal was in the initial stages of infection. There are previous records of D. immitis in coyotes and stray dogs in Querétaro, but this nematode has yet to be registered in this host species.
