This study was performed to observe the present status of intestinal parasitic infections among the children in Iksan, Jeonbuk, Korea. During the period from February to June 1996, total 510 fecal samples(male 276, female 234) were collected and examined by formalin-ether sedimentation technique and trichrome stain for intestinal helminths and protozoan cysts. Of 510 samples examined, 62(12.2%) were positive for intestinal parasites. Helminth egg positives were 3(0.6%), and protozoan cyst positives were 59(11.6%). The female group showed higher positive rate(13.2%) than males(11.2%), and the highest positive rates were observed in 7 age group(17.5%), and lowest positive rates were 4 age group(9.5%). 3 species of helminths egg and 6 species of protozoan cyst were detected; Metagonimus yokogawai 0.4%, Enterobius vermicularis 0.2%, Trichuris trichiura 0.2%, Endolimax nana 4.1%, Entamoeba coli 3.9%, Ciardia lamblia 2.0%, Entamoeba histolytica 1.4%, Iodamoeba butschilii 0.8%, and Chilomastix mesnili 0.4%, respectively. In 3 helminth egg positive cases, single infection was 2(66.7%), and double infection 1(33.3%), among 59 protozoan cyst positives, single infection was 54(91.5%), and double infection was 5(8.5%). The highest positive rate of protozoan cyst was 7 age group(14.3), and lowest positive rate was 4 age group(9.5%).
