Ornithobilharzia turkestanicum from genus Ornithobilharzia genus and family Schistosomatidae is an important agent of parasitological infection in sheep. This parasite has been reported from Russia, China, Turkestan (Kazakhstan, Kyrgyzstan, Turkmenistan and Uzbekistan), Pakistan, Iraq, Turkey and Iran. Parasitological infection due to this agent could be one of the important factors of decreasing the production rate of livestock in Iran. The purpose of this study, was to experimentally infect sheep with this parasite and confirm the infection by post-mortem examination and Histopathology which was done successfully. Twenty five sheep were used in the study of which 10 sheep were experimentally infected by Ornithobilharzia turkestanikum using subcutaneous injection and 10 sheep by skin contact method and the other 5 sheep were kept as control. Result of post-mortem and Histopathology during a one year period confirmed that all of sheep were infected and adult worm, were seen in their mesentery. Mean number of cercaria used for inducing the infection was 6425 and 462 adult worms were collected post-mortem. There was no significant relationship between the number of cercaria and adult worms collected. Male sheep were more infected than female.
