AI Article Synopsis
- A study in Oddar Meanchey Province, Cambodia, analyzed fecal samples from 1,287 individuals between May 2007 and November 2009, finding an overall intestinal helminth egg positivity rate of 23.9%.
- The most common helminth detected was hookworms, affecting 21.6% of the population, with other species including echinostomes and Enterobius vermicularis present at lower rates.
- For the first time in Cambodia, adult echinostomes were recovered and identified as Echinostoma ilocanum after treating two patients with praziquantel, marking a significant finding in the region's parasitology.
Article 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.
