Abstract
Hugot (1983), Hugot and Tourte-Schaefer (1985) reported that nematodes of the genus Enterobius causing human enterobiasis might be classified into two different species on the basis of the size and shape of spicule in male worms. E. gregorii Hugot, 1983 has significantly shorter spicules in males than those in E. vermicularis. A total of 194 male Enterobius were collected from 17 schoolchildren by anthelmintics at Wonju, Kangwon-do. The sizes of spicules and morphologies were comparatively observed. Two different types of spicules in male Enterobius were also observed in Korea. Out of 112 male worms observed, the percentages of E. gregorii (short-spicule type) and E. vermicularis (long-spicule type) were 23.2% and 76.8%, respectively.
