|
Ullung-do is a solitary island in the East Sea of Korea. During October 1972-.´June 1973, a total of 695 among 27, 085 islanders was surveyed on the infection of intestinal parasites by the modified MIFC method (Cho et al., 1972). The results are summarized as follows:
1. Of 695 specimen examined, male was 367, and female numbered 328. The total positives for intestinal helminths were 408 (58.7%); Ascaris lumbricoides 39.4%, Trichuris trichiura 33. 8%, hookworm 0.6%, Trichostrongylus orientalis O. 9%, Enterobius vermicularis 0.2%, Clonorchis sinensis 0.4% and Taenia species 0.9%.
2. The total positives for intestinal protozoa were 173(25.2%); Entamoeba histolytica 5. 5%, Entamoeba colt 19. 1%, Endolimax nana 3.2%. lodamoeba biitschlii 0.1%, Giardia lamblia 2.9% and Chilomastix mesnili 0.3%.
3. The intestinal helminths and protozoa were more prevalent in female than in male. Age group of 40^´49 years showed the highest infection rate whereas the group of less than 10 years revealed lower rate.
4. Incidence of intestinal parasites in this island was relatively lower than that of the - other islands and rural inland areas in Korea.
