Himasthla alincia (Echinostomatidae): metacercariae in brackish water bivalves and their growth and development in experimental animals.
J Parasitol. 2009 Dec; 95(6):1415-20.JP

Abstract

Metacercariae of Himasthla alincia (Echinostomatidae) were discovered in brackish water bivalves in the Republic of Korea; their growth and development were observed in experimental animals. Five species of clams (Mactra veneriformis, Solen grandis, Meretrix petechialis, Cyclina sinensis, and Tapes philippinarum) were found to harbor the metacercariae of H. alincia. Chicks, rats, and mice were orally fed the metacercariae, and worms were recovered from their intestines from day 1 to day 20 postinfection (PI). Only chicks appeared to be a fairly suitable host, although the worm recovery was low, i.e., 1.5% from 17 chicks, and the number decreased from 2.6% on day 1 PI to 1.3% on day 20 PI. Worm development in chicks was quick and remarkable during days 10–20 PI. Adult flukes were morphologically characterized by the presence of a head collar with 31 dorsally uninterrupted collar spines, including 4 end-group spines, and distribution of vitellaria only up to the most posterior margin of the cirrus sac. We verified that several species of brackish water clams are second intermediate hosts for H. alincia, and that its life cycle occurs in the Republic of Korea.
