[Intestinal parasite survey in Seoul by stool examination at Hanyang University Hospital]
The present study was undertaken to evaluate the present status of intestinal parasitic infection in Seoul area, Korea. During the period from June 1985 to July 1986, a total of 5,251 stool samples were collected in Department of Clinical Pathology, Hanyang University Hospital and examined by formalin-ether sedimentation technique once for helminth ova and protozoan cysts. The results were summerized as follows: The overall egg positive rate of intestinal helminthes was 2.53 per cent; and 1.43 per cent for Clonorchis sinensis, 0.7 per cent for Trichuris trichiura, 0.13 per cent for Metagonimus yokogawai, 0.06 per cent for hookworm, and 0.02 per cent for Ascaris lumbricoides, Diphyllobothrium latum and Hymenolepis nana, respectively. The overall cyst positive rate of intestinal protozoa was 1.07 per cent. Cyst positive rate was 0.06 per cent for Entamoeba histolytica and 0.13 per cent for Giardia lamblia, respectively. Higher prevalence of intestinal parasitic infection was observed in male and in 21-50 year-old groups. The highest prevalence of Clonorchis sinensis infection was observed in 40th age group(3.4 per cent), and male (2.3 per cent) was more infected than female (0.7 per cent) in general.
