Snails were sampled in the dry season (March 2022) and the rainy season (May 2022). Only snails in Kenh Lang - Ben Muong canal were infected trematodes. Furcocercous cercariae were recovered from Clea helena in the dry season with a prevalence of 2.3%. Xiphidio cercariae were found in Sinotaia lithophaga (in the dry season) and Filopaludina sumatrensis (in two seasons) with a prevalence of 4.0% and 3.5%, respectively. The trematode prevalence in the dry season was higher than in the wet season
however, there was no significantly different for Filopaludina sumatrensis (P>
0.05). The findings provided information about the diversity of snails and trematode infection in the area. Further research in the different water bodies should be done in Cu Chi district and other places to identify the infected snail species and conserve the rare and precious snail species.
