In this study, echinostome metacercariae from three species of <em>Filopaludina </em>snails; <em>Filopaludina martensi martensi, F. dorliaris </em>and <em>F. summatrensis polygramma</em> were collected from four districts of Lamphun and Lampang Provinces and the prevalence of metacercrial infection by the three species was 27.05%, 41.92% and 48.05% respectively. The adult flukes were covered from experimentally infected hamsters and chickens at the 14<sup>th</sup> day after infection and were identified to species using light microscopy (LM), scanning electron microscopy (SEM), and a phylogenetic tree for the mitochondrial gene ND1 (nicotinamide adenine dinucleotide dehydrogenase subunit 1). This fluke has an elongated body, entrally curved body , head collar with 37 prominent collar spines, and 2 type of testes shape including lobed and roudned. However, identification of <em>Echinostoma revolutum</em>in this present study has been based on morphology, morphometric data, and the phylogenetic tree from ND1 subunit The results confirmed status of <em>E. revolutum</em> in <em>Filopaludina</em> spp. snails as the natural second intermediate host and also demonstrated the occurrence of this intestinal flukes in Lamphun and Lampang provinces.</p>}, number={2}, journal={Life Sciences and Environment Journal}, author={Sakda, Patthanan and Wongsawad, Pheravut and Wongsawad, Chalobol}, year={2018}, month={Sep.}, pages={306–315} }
