The existence of life cycle of Heterophyes
heterophyes nocens, in three southern coastal
areas of Korea, i.e., Hadan Dong, Pusan City;
Geoje Island, South Kyongsang Do and YongsanpoEup, South Cholla Do, was proved by
identifying the metacercariae in mullets, Mugil
cephalus, and by obtaining adult worms from
experimental animals during the period from
May 1978 to October 1979.
Infection rates of the mullets with the metacercariae
were from 5.9% to 12.7% according
to areas and a total of 821 metacercariae were
collected from 11 infected mullets. And a total
of 88 adult worms were recovered from small
intestine of the experimental animals on the
3rd to 20th day after infection. The size of
the worms increased according to the age of
The adult worms were distinct with a genital
sucker near the ventral sucker. A total of 52~
62 rodlets are arranged in a row on the genital
sucker. So they were identified as Heterophyes
heterophyes nocens (Onji et Nishio, 1916). The
possibility of prevalence of human infection
in southern coasts, Korea was suggested and
