چکیده	Background and objectives: Upon recent finding of a new Gongyloema species (G. nepalensis) in domestic and wild ruminants in Asia and Europe, this study aimed to investigate the rate of infection in cattle, sheep and goats slaughtered in Hamedan, and sheep and goats in Babol slaughterhouse. Methodology: From March 2018 to June 2019 full-length esophagi were collected from 968 livestock including 384 cattle in Hamedan slaughterhouse and 584 sheep and goats (384 from Hamedan and 200 from Babol). In laboratory esophagi were inspected and the worms embedded in tissues were carefully retrieved, preserved in ethanol containing gylcerin and identified morphologically. Results: Out of 384 examined esophagi of cattle three (0.8%) harbored Gongylonema. Morphological characteristics nematodes were consistent with G. pulchrum. Parasites were found in first proximal portion (n=2) and middle portion (n=1) of the esophagi. No pathologies attributed to gongylonemiasis were found in this study. Infection was not observed in small ruminants. Discussion and Conclusion: This study provides the first information about infection of livestock in Hamedan province with Gongylonema. Low infection rate of cattle and absence of infection in small ruminants of Hamedan shows that infected intermediate hosts are not abundant in the area and so risk of human infection is low. Absence of infection in sheep slaughtered in Babol might suggest that climate change and/or improvement of rearing conditions and hygiene measures led to this decrease. Further epidemiological studies with aid of molecular biology tools are necessary to find out if G. nepalensis does occur in Iran.
