Road Killed Carnivores Illustrate the Status of Zoonotic Helminthes in Caspian Sea Littoral of Iran

Carnivore carcasses on the roads can be regarded as study materials in parasitology and eco-epidemiology. Stray carnivores such as dogs and cats are known to harbor so many different pathogens like zoonotic helminthes. The current investigation, apparent the status of the helminthic parasites found in road killed carnivores from different parts of Guilan Province north of Iran.
Fifty road killed carnivores including 27 stray dogs (Canis familiaris), 11 golden jackals (Canis aureus) and 12 stray cats (Felis catus) were collected from 21 locations of Guilan Province, during Apr to Nov 2015. Internal organs of the carcasses, including digestive tract, heart, kidneys, lungs, liver, skin, eyes as well as muscles were carefully inspected and sampled for helminthological investigation.
About 80% of the 50 carnivores, (stray dogs 77.77%, golden jackals 81.81%, and stray cats 91.66%) were found naturally infected with helminthic parasites. Dipylidum caninum, Toxocara cati, Toxocara canis, Toxascaris leonine, Ancylostoma caninum, Ancylostoma tubaeforme, Dirofilaria immitis, Dioctophyma renale, Dipylidum caninum, Echinococcus granulosus, Mesocestoides spp., Taenia hydatigena, Taenia hydatigera, Joyuxiella spp., Spirometra spp. are reported herein.
The prevalent occurrence of zoonotic helminthes such as T. canis, T. cati, T. leonina, E. granulosus, D. immitis and D. renale in stray carnivores should be considered as a public health hazard, specifically within a vast tourism area like Guilan Province.
