Abstract

Objective: To determine the Lymnaea stagnalis snails’ infection with trematodes larval stage in one of the springs of the Shahrekord city in Chahar Mahal and Bakhtiari. Methods: To determine the snail infection to trematodes larval stages, the snails were caught from the field, and transferred to the Parasitology Department of Razi Vaccine and Serum Research Institute. Then stimulating of snails by light, tubing and squashing of them were used for detection and identification of the isolated cercariae. Results: Of 400 collected snails from the referred springs, 350 of them identified as Lymnaea stagnalis. Observed cercariae were identified and classificated as order Plagiorchis, family Plagiorchiidae and genus Opisthioglyphe and Plagiorchis. Conclusions: In Chahar Mahal and Bakhtiari Province, due to having more than 10% of water content of country, ecological conditions can play important role to develop sensitive snail especially Lymnaeidae and be considered as a critical and suitable habitat for them.
