| Abstract | Melanoides jugicostis Hanley and Theobald (1876), a freshwater snail was reported as a species with very wide distribution ranging from Burma to Thailand and down to Java island of Indonesia. In Thailand, this species was found to live in a few localities. However they can transmit various kinds of parasites of animal and human trematodes. The aim of this study was to evaluate the natural infections of M. jugicostis snail in Thailand. The investigation was done by non systematic randomize collection only for adult snails during February to March in 2012. The collected snails were then examined for trematode infections by shedding and crushing techniques. The comparative analysis on morphology and anatomy of cercariae used for differentiating the species of parasite were done by describing from living and fixed cercariae. A total of 555 snails were collected, 103 were foundpositive for cercarial infections. The overall infection rates was 18.6% (103/555). Four types and four species ofcercariae were categorized. Of these types were Parapleurophocercous cercariae (Haplorchis pumilio), Pleurophocercous cercariae (Centrocestus formosanus), Xiphidiocercariae (Loxogenoides bicolor), and Furcocercous cercariae (Alaria mustelae). The overall infection rates of these parasites were 16.04%, 0.54%, 1.08%, 0.72%, and 0.18%, respectively. |
