Domestic dog as a human health hazard in north of Iran

Abstract

An epidemiological study was conducted to determine the prevalence of helminthic parasites of domestic dogs using stool samples in north of Iran in 2013. Stool samples (nآ =آ 100) were collected from domestic dogs of different ages and genders. Different techniques including wet smear, formalin-ether sedimentation method and flotation technique in saturated zinc chloride solution were performed on collected stools to detect eggs and larval stage of helminthes parasites. The overall prevalence of helminthic parasites of examined stools of dogs was 57آ %. The examined domestic dogs harbored eggs of eight species of helminthes including: Taenia spp., Diyplidium caninum, Toxocara canis, Toxascaris leonina, Capillaria aerophila, Mesostesphanus spp. and Trichuris volpis. T. canis and T. volpis were the most and least prevalent eggs, respectively. No significant statistical differences were observed between infection by helminthic parasites and both gender and age of the dogs (Pآ >آ 0.05). Considering high level of helminthic infection in the stool of examined domestic dogs, a contiguous educational program to increase awareness of dog owners and an effective anti-parasite control programmed is highly recommended in order to reduce the danger of zoonotic diseases in north of Iran. This is the first report of C. aerophila and Mesostesphanus spp. from dog in Iran. آ© 2014, Indian Society for Parasitology.
