Since the Gordius worm is a parasite of crickets and several arthropods, cases of humans infected with this worm have been rare and accidental. A Gordius worm was obtained from a three-year-old girl who consulted a local clinic in Gwangju, Kyunggi-do, Korea. She lived in a rural area, and had eaten an insect that looked like a cricket. She expelled the worm in vomitus 15 minutes later; in fact, she expelled two worms, but one was discarded. The worm had a grayish white color and an intact outer surface. It was 16 cm in length and 0.6 cm wide. The posterior end of the worm was spirally enrolled and furcated into two caudal lobes, which were nearly cylindrical but showed a somewhat concave medio- ventral surface. The cloacal aperture was round and situated anterior to the point of bifurcation of the lobes. The cloacal aperture was encircled by a dark ring, which was a little removed from the aperture. The crescent fold was reddish brown, and no hairs were noticed over the entire body surface. The worm had the morphological features of a male Gordius. Accidental human cases involving the Gordius worm are rare and this is the first such case in Korea.
由于铁线虫是蟋蟀和几种节肢动物的寄生虫，人类感染这种寄生虫的病例罕见且多为偶然。一条铁线虫取自一名三岁女童，该女童前往韩国京畿道光州的一家当地诊所就诊。她生活在农村地区，曾食用过一种看起来像蟋蟀的昆虫。15分钟后，她通过呕吐排出了这条虫子；实际上，她排出了两条虫子，但其中一条被丢弃了。这条虫子呈灰白色，体表完整。它长16厘米，宽0.6厘米。虫子的后端呈螺旋状卷曲，分叉成两个尾叶，尾叶近乎圆柱形，但腹面中部略显凹陷。泄殖孔呈圆形，位于尾叶分叉点前方。泄殖孔被一个深色环包围，该环与泄殖孔稍有距离。新月形褶皱呈红棕色，整个体表未发现毛发。这条虫子具有雄性铁线虫的形态特征。涉及铁线虫的人类偶然病例罕见，这是韩国首例此类病例。
