gastrointestinal helminthic parasites in stray cats (felis catus) from north of iran

background : cats play a crucial role in the epidemiology of gastrointestinal helminthic parasites and also play a major role in transmitting of these parasites through faecal contamination of soil, food or water. the aim of this study was to determine the species of gastrointestinal helminthes parasites in stray cats from a rural area of bandar-e-anzali, iran. method: gastrointestinal helminthes were collected from 50 necropsied stray cats ( felis catus ) after capturing them by trapping from different regions of the city and humanely euthanatized in bandar-e-anzali, a port in the caspian sea in northern iran, from march to november 2003. results: the prevalence of infection was 90%, with those of individual parasites being diplopylidium nolleri 54%, phy­saloptera praeputialis 32%, ancylostoma tubaeforme 20%, joyeuxiella pasqualei 10%, toxocara cati 8%, pterygoderma­tites affinis 6%, ancylostoma caninum 4%, and taenia taeniaeformis 2%. concurrent infections with two or more parasites were recorded in 34% of the individuals. in relation to the sex, the differences were not significant. conclusion : p. praeputialis, t. cati, d. nolleri and sometime j. pasqualei are the commonest helminthes in cats. this is the first reported isolation of p. affinis and a. caninum infections from cats in iran.
