چکیده

background: the aim was to study the gastro-intestinal helminths of stray dogs of garmsar, sem­nan province, central iran, and its impacts on human health and animal production. methods : during 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around garmsar, were removed, and examined for helminth infections. subsequently helminths were collected from the contents of each part and scraped sample of small intestines of washed materials in a 100-mesh sieve. to identify the species of helminths, the nematodes were cleared in lactophenol and cestodes were stained using carmine acid. results : mixed infection was the rule and 40 dogs (80%) harbored more than one species of helminth. taenia hydatigena was the most prevalent species (80%) followed by echinococcus granulosus (64%), toxocara canis (22%), mesocestoides lineatus (12%), taenia multiceps (10%) and dipylidium caninum (4%). the mean intensity of worm infection was low (1-3) ex­cept for that of e. granulosus (645). no significant difference was noticed between sex, age and most helminth infections except for that of sex and t. hydatigena   ( p =0.001) as well as age and t. canis ( p =0.001). c onclusion:   although human infection with t. hydatigena is unlikely, but other helminths re­ported in this study are of zoonotic importance, and may pose a threat to community health, and reduce the productions of ruminants harboring taeniid metacestodes.
