Prevalence of parasitic infections in the red fox (Vulpesvulpes) and golden Jackal (Canis aureus) in Iran

Red foxes and golden jackals are the two most abundant wild carnivores of Iran which have the ability to adopt a variety of habitats and human proximity. Despite this, very few investigations on their helminth and none on their external parasites infections have been carried out in Iran. Between 2003 and 2004, a total of 79 jackals and 37 foxes were collected from 3 different climatic zones of Iran and examined for helminth and ectoparasite infections. A number of parasites including: Mesocestoides lineatus, Taenia hydatigena, Dipylidium caninum, Diplopylidium nolleri, Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Onicola canis, Dirofilaria immitis, Rhipicephalus sp., Ctenocephalides canis and Pulex irritans were common parasites between jackals and foxes, whereas Echinococcus granulosus, Spirocerca lupi, Rictularia affinis, Macracanthorhynchus hirudinaceus, Dermacentor sp. parasitized jackals and Jeuyoxiella pasquali, Ixodes ricinus, Haemaphysalis sp. were collected only from foxes. All ectoparasites, S. lupi and O. canis reported from jackals and foxes in this study represent new host and distribution records.
