Abstract

Trematodes of the family I Ictcrophyidac in man and carnivores were studied in Khuzcstan, south-west Iran.Hight hundred and eleven stool samples from a population of 3400 in 13 villages in a swampy area located incentral Khuzcstan were examined by the formalin-ether concentration technique. The following helminths were found: Ascaris lumbricoides 7%, Trichostronayius spp. 53%, hookworms 4%, Trichuris trichiura 5%, Hywenolepis nana 12% and hetcrophyid spp. 8%. Post-mortem examination of carnivores revealed that 14·2% of jackals, 33·3% of foxes and 2·5% of dogs were infected with hctcrophyids, namely Metagonimus yokogawai, Heterophyes heterophyes and H. katsuradai. The freshwater snails Melanoides and Melanopsis spp. and brackish water fishes ltarhus spp. and Mugil spp. were thought to be the intermediate hosts of these flukes in this area. This is the first report of hctcrophyid infection in man and carnivores in Iran.
