This study aimed to investigate the infection rate of larval fluke in intermediate hosts in freshwater snails in Wang Chik Watergate area, Pho Prathap Chang District, Phichit Province and study on feces infection of worms in people in Rang Nok Subdistrict, 397 samples were obtained, and worm eggs were detected using the Modified Kato Katz method and the intermediate hosts were surveyed in 20 freshwater snails in Wang Chik Subdistrict, totaling 4,336 samples, by the Shedding and Crushing method. Data were collected from August to September 2021. The study found that 3 individuals were infected with worm disease. The overall helminth infection rate was 0.75%. Two types of worm eggs or larvae were identified: Ascaris lumbricoides in 2 cases, accounting for 0.50%, and minute intestinal fluke in 1 case, accounting for 0.25%. Results of the study on the types and infection rates of cercariae larvae in freshwater snails from 20 locations in 10 villages in Wang Chik Subdistrict, with a total of 4,336 samples collected, classified into 15 species of freshwater snails, namely: 1. Anentome Helena 2. Bithynia funiculata 3. Bithynia pulchella 4. Bithynia siamensis siamensis 5. Filopaludina sumatrensis polygramma 6. Brotia costula costula 7. Filopaludina filose 8. Radix auricularia rubiginosa 9. Filopaludina martensi martensi 10. Tarebia granifera 11. Idiopama dissimilis 12. Indoplanorbis exustus 13. Melanoides tuberculata 14. Physa acuta 15. Pomacea canaliculata. and found 53 larvae of small intestinal flukes of vertebrates, accounting for 1.22 %. The type of shellfish found is Bithynia siamensis siamensis, Bithynia siamensis siamensis, Filopaludina sumatrensis polygramma, Filopaludina filosa, Bithynia funiculata, Indoplanorbis exustus. Three freshwater snails were found to be infected with leaf fluke disease, accounting for 0.07 %. The species found were Indoplanorbis exustus and Melanoides tuberculata. This study found no evidence of schistosomiasis infection in the population and no presence of Neotricula aperta snails, which are intermediate hosts for human blood flukes. This finding is of high significance for water resource development.
