| stellantchasmus falcatus (digenea: heterophyidae) in cambodia: discovery of metacercariae in mullets and recovery of adult flukes in an experimental hamster. | stellantchasmus falcatus (digenea: heterophyidae) is first reported from cambodia through recovery of the metacercariae from mullet fish and adult flukes from an experimentally infected hamster. we purchased 7 mullets, chelon macrolepis, in a local market of phnom penh, cambodia, and each of them was examined by the artificial digestion method on may 2010. the metacercariae of s. falcatus were detected in all mullets (100%) examined, and their average density was 177 per fish. they were elliptic ... | 2016 | 27658608 |
