Background and PurposeTrichostrongylid helminths play a significant role in economic loss in livestock and human health. Due to the need to knowledge of the latest status of helminth infection of domestic ruminants, for proper planning to prevention and control, this study was conducted to determine of Trichostrongylidae helminths. Materials and MethodsA total of 334 intestines and abomasums purchased from slaughterhouse of Sanadaj, Kurdestan. The samples were placed in 10% formalin separately and examined in the Parasitology Laboratory of Sanandaj and Hamadan Medical School. All nematodes identified using the appropriate keys. The results were recorded in a form along with information such as livestock type, sex, farming location. ResultsTotally, 178 sheep samples (53.29%), 93 goat samples (27.85%) and 63 cattle samples (18.86%) were studied. The prevalence of intestine infection was 18.31% and abomasum was 81.69% and the overall infection in this study was 20.95%. Only two samples (0.6%) of Trichostrongylus sp. were isolated, most of them were female. The most isolated species was T. longispiculis. The highest percentage of isolated worms was Ostertagia ostertagi (22.18%). Most cases of intestinal nematode were Nematodirus abnormalis (14.28%) and in abomasum O. circumcicta (18.57%).ConclusionAlthough Trichostrongylus infection has decreased in recent years; a 0.6% prevalence were found in present study. However, infection with other Trichostronegilids in the studied animals has a relatively high prevalence. Due to the economic loss in livestock and the possible role of these parasites in transmitting to humans, appropriate control and treatment measures should be taken.
