ABSTRACT
The occurrence of larval Dicrocoelium dendriticum and Brachylaima sp. is described with molecular evidences in gastropod intermediate hosts from Fergana Valley, Uzbekistan. Larvae of D. dendriticum were detected in 28 (10.7%) out of 262 Xceropicta candacharica, and 8 (9.7%) of 82 Angiomphalia gereliana. Brachylaima sp. larvae were found in 3 (1.6%) of 95 Pseudonapaeus sogdiana. The total number of larvae per snail varied from 8 to 110 individuals. Alignment of the first four sequences of 28S rDNA was revealed a 99-100% similarity to D. dendriticum. Larvae from P. sogdiana snails were 98% similar to Brachylaima sp. In this study, it was confirmed that 2 species of terrestrial snail, X. candacharica and A. gereliana, act as the first intermediate hosts of D. dendriticum, and P. sogdiana snail play a role of intermediate host of Brachylaima sp. in the Fergana Valley, Uzbekistan.
