Abstract

Aim:The present study aims to focus on the role of common marine snails (Littorina littorea) as a vector for some trematode parasites.Materials and Methods:A total of 327 marine water L. littorea snails were collected during the summer of 2016 from a Qarun lake in the EL-Fayoum Governorate, Egypt. The snails were investigated for infection by trematode parthenitae through induction of cercarial shedding by exposure to light and crushing the snails. The species were stored in Search Laboratory of Zoology Department, Faculty of Science, Fayoum University.Results:Three species of Strigeid littorina cercaria were identified from the infected snails. They are described here and they identified in relation to close-up morphological features and linked to its snail hosts. They give the following names: Cercaria strigeid littorina type 1, C. strigeid littorina type 2, and C. strigeid littorina type 3. The incidence of infection by these cercariae was 33%, 25.7%, and 2.4%, respectively.Conclusion:This study is clarifying the importance of this marine snail as intermediate hosts for new trematode species.

Highlights

Lake Qarun is the third largest lake in Egypt and the second most famous one after Lake Nasser in the Southern part of Egypt

As described in Table-1, three cercariae and their parthenitae were diagnosed in the inspected snail

Summary

Introduction

Lake Qarun is the third largest lake in Egypt and the second most famous one after Lake Nasser in the Southern part of Egypt. It lies 45 m below sea level and occupies the lowest, northern section of the Fayoum depression. The study of animal parasites in the Lake Qarun region began with the report of Al-Bassel [1] and Abdel-Ghaffar et al [2,3]. Parasites might impact behavior at the level of animal personalities (Hammond-Tooke et al [6] and Poulin [7]) as well as at the sample mean. Only a few studies [6,8,9] have investigated this possibility empirically
