Melanoides kainarensis – новый промежуточный хозяин трематоды Philophthalmus lucipetus (Trematoda, Philophthalmidae)

Abstract

Objective of research: to study the infection level of molluscs Melanoides kainarensis Starobogatov et Izzatullaev, 1980 with cercariae of trematode Philophthalmus lucipetus (Rudolphi, 1819) under conditions of Uzbekistan. Materials and methods: Cercariae and parthenitae of Ph. lucipetus of molluscs M. kainarensis from the warm spring Boshkhovuz of Samarkand region, Uzbekistan were investigated. Morphological and biological studies were carried out by well-known standard parasitological methods. Results and discussion: The research revealed that 2801 specimens of M. kainarensis were infected with cercariae and parthenitae of Philophthalmus Looss, 1899, which were identified as Ph. lucipetus. The collected cercariae and adolescariae were used for the experimental infestation with Anser anser dom., Anas platyrhynchos dom. and Gallus gallus dom. Adult parasites isolated from conjunctival sacs of infected birds were identified as Philophthalmus lucipetus. That was the first evidence for the role of M. kainarensis as the intermediate host for these trematodes.
