Abstract

Canids are reservoir for some zoonoses helminthic disease. They are one of main public health problem. The
aim of this study was to ascertain frequency of gastrointestinal helminthic infection of stray dogs in Zabol city,
southeaster of Iran. In this descriptive study, 30 stray dogs were euthanized, intestine was removed by necropsy.
Then, the intestines was opened by scalpel and their contents passed through mesh sieve. The helminth were
collected. The nematodes were preserved in 70% ethanol with 5% glycerin and cestodes were preserved in 70%
ethanol. The cestodes were stained by acetocarmine. The nematodes were cleared by lactophenol. The genus and
species of helminth were identified by identification keys. Twenty tow (73.3%) of stray dogs had at least one
intestinal helminthic infection. Recovered helminth from stray dogs include: Taenia hydatigena, Taenia ovis,
Taenia multiceps, Mesocestoides spp, Toxocara canis, Toxocara cati. Data showed that the stray dogs in Zabol

Abstract [French]

Les canidés représentent un réservoir pour différentes zoonoses d’origine helminthique impactant la santé publique. L’objectif de cette étude était de déterminer la fréquence des infections gastro-intestinales helminthiques chez les chiens errants de la ville de Zābol, située au sud-est de l’Iran. Une étude descriptive a été menée sur les intestins de 30 chiens errants euthanasiés. Les intestins ont été prélevés lors d’une autopsie et leurs contenus passés à travers un tamis pour récolter les helminthes. Les nématodes ont été conservés dans une solution composée de 70% d’éthanol et 5% de glycérine. Les cestodes ont été préservés dans de l’éthanol à 70%. Ces derniers ont été ensuite colorés à l’acétocarmine alors que les nématodes ont été éclaircis avec du lactophénol. Le genre et l’espèce des helminthes ont été identifiés à l’aide de clés de détermination. Vingt trois chiens (73.3%) présentaient au minimum une infection intestinale helminthique. Les helminthes identifiés appartenaient aux espèces suivantes : Taenia hydatigena, Taenia ovis, Taenia multiceps, Mesocestoides spp, Toxocara canis, Toxocara cati. Ces données montrent que les chiens errants de la ville de Zābol sont porteurs d’importantes zoonoses d’origine helminthique comme celles provoquées par le genre Toxocara.
