Abstract Fecal examinations using the Kato Katz technique were performed on a total of 1,287 villagers (945 students and 342 general inhabitants) of Oddar Meanchey Province, Cambodia in May 2007 and November 2009. The overall intestinal helminth egg positive rate was 23.9\%, and the most prevalent helminth species was hookworms (21.6\%). Other helminth eggs detected included echinostomes (1.0\%), Enterobius vermicularis (0.8\%), small trematode eggs (0.7\%), which may include Opisthorchis viverrini and Haplorchis spp., and Hymenolepis nana (0.4\%). In order to recover adult echinostomes, we treated 2 patients with 10-15 mg/kg praziquantel and purged. Total 14 adult echinostomes, 1 and 13 worms from each patient, were collected. The echinostomes characteristically had 49-51 collar spines and 2 round or slightly lobated testes. They were identified as Echinostoma ilocanum (Garrison, 1908) Odhner, 1911. So far as literature are concerned, this is the first record on the discovery of human E. ilocanum infection in Cambodia.
