| discrimination 28s ribosomal gene of trematode cercariae in snails from chiang mai province, thailand. | trematode cercariae are commonly found in many freshwater gastropods. these cercariae can serve to identify the occurrence of such trematodes as centrocestus formosanus, haplorchis taichui, haplorchoides sp, and stellantchasmus falcatus, which are important parasites in chiang mai province, thailand. as the species of these cercariae cannot be identified accurately based on morphology, this study employed sequencing of a fragment of 28s ribosomal dna and phylogenetic analysis to identify the tre ... | 2016 | 27244956 |
