Abstract

A species of metacercariae recovered from the fresh-water fish, collected from Kaumji (Pond), Kaechonji (Pond) and Ssanggyechon (River). Uisong-gun, Kyongsangbuk-do, Korea, was identified as Clinostomum complanatum by morphological observation and experimental infection to chicks. The excysted metacercariae, tongue-shaped and progenetic, were 3.28-4.27 mm in length and 0.94-1.46 mm in width. The adult flukes recovered from the chicks four days after infection were 4.20-4.86 mm long and 1.14-1.49 mm wide. Twelve species of the fresh- water fish were found to be infected with the metacercariae. The infection rate ranged from 1.6% (Zacco temminkii) to 88.9% (Acheilognathus rhombea and Microphysogobio yaluensis). The intensity was highest in Carassius auratus (13.0/fish infected) and the abundance (relative density) was highest in A. rhombea (7.8/fish examined). This survey demonstrated for the first time the source of human infection by C. complanatum in Korea.
