Abstract

An epidemiological study for the intestinal trematode infection of the villagers was done in Koje-myon, Kochang-gun, Kyongsangnam-do, Korea in March, 1994. Of 116 stool specimens examined, total helminthic ova positive cases were 13 (11.2%) and cumulative ova positive cases 21 (18.1%): Echinostoma hortense 11 cases (9.5%), Metagonimus sp. 6 cases (5.2%), and Clonorchis sinensis 4 cases (3.4%). After the treatment and purgation, variable numbers of E. hortense, 6 to 227 per person, were collected from 7 echinostome egg positive cases, together with M. takahashii in 6 cases. Three adult flukes of E. cinetorchis were collected from one person and one Stellantchasmus falcatus was recovered from another case. This mountainous village was proved to be one of the endemic foci of echinostomiasis in Korea.

Fig. 1
Echinostoma hortense collected from Park OO (54/M) in Table 1 has laterally deviated ovary, and two distict testes (arrowheads) at equatorial protion. Acetocarmine stained. Bar = 1 mm.


Fig. 2
One of 3 Echinostoma cinetorchis collected from Park OO (54/m) in table 1 has one reduced testis (arrow) located posteriorly to ovary. Acetocarmine stained. bar = 1 mm.


Fig. 3
Metagonimus takahashii collected from Park OO (54/M) in Table 1. No poseteriormost location of right testis (R), separated left testis (L) from the right one, distribution of uterine tubule over the left testis and intertesticular junction, vitellaria passing through the posteriormost poriton of the body. Unstained. Bar = 100µm.


Fig. 4
Stellantchasmus falcatus collected from Kim OO, showing well-developed seminal vesicle, two testes (arrowheads) and many uterine eggs. Unstained. Bar = 100 µm.
