Identiication of Lymnaea gedrosiana Snail as Intermediate Host of Schistosoma Turkestanicum in Boroujerd Area

Snail transmitted diseases are very important group of parasitological diseases. Fresh water snails act as intermediate host for trematodal parasites. The role of these snails as intermediate host has got the importance from the view point of environmental safe systems and public health. Snails are from family Lymnaideae, order Basommatophora, subclass pulmonata and class Gastropoda. Lymnaea gedrosiana snail measures from 11 to 16 millimeter. The shell of L. gedrosiana is very similar to Lymnaea peregra. Lymnaea gedrosiana is very similar to L. auricularia from the point of anatomy. The most prevalent lymneae genus snail in Iran is L.gedrosiana and could be found in every place of Iran. Snails as the intermediate hosts of Schistosoma and Fasciola are very importants from the medical and veterinary viewpoints. It was decided to collect snail samples of Lymnaea genus in (Lorestan, Borojerd) district. Snail samples were transport to special laboratory (Department of Parasitology). At razi institute six hundreds Lymnaea samples were identified from Silakhor plateau and Shirvan village. L. gedrosiana comprises eighty percent of all collected samples, when 600 other samples were collected from other regions of this place and none of them was L. gedrsosiana, then the rate of L. gedrosiana in all parts was estimated to 40 percent. This study was the first case of L. gedrosiana from Boroujerd region.
