Sheep play an important role in national economy and social economy in rural areas in Iran. The main goal of this study was to investigate the fauna and frequency of parasitic helminth infections prevalent in native sheep in Hamedan, western Iran. From April 2010 to March 2011, the gastrointestinal and respiratory tracts of 100-sheep were examined using conventional parasitological methods. The overall infection rate was found as 69%. No infection was found in esophagus and rumens. Parabronema skerjabini (22%) and Ostertagia circumcincta (1%) were recorded as the maximum and minimum cases for the presence of nematode, respectively. On the other hand, the most dominant of trematode and cestode were Fasciola hepatica (13%) and Monezia expansa (13%), respectively. The highest infection rate was reported in summer (84%). The prevalence of helminth infection was varied among gender, seasons and age groups. In conclusion, this is the first report of parasitic helminth infections in sheep in Hamedan province in western Iran. Our results provide baseline information for the future studies.
