The autoinfective filariform larva of Strongyloides stercoralis causes hyperinfection in immunosuppressed hosts. Here we report on the case of a male patient who was admitted to the emergency room at Gwangju Veterans Hospital with a complaint of dyspnea, and who was receiving corticosteroid therapy for asthma. Many slender larvae of S. stercoralis with a notched tail were detected in Papanicolaou stained sputum. They measured 269 +/- 21.2 microm in length and 11 +/- 0.6 microm in width. The esophagus extended nearly half of the body length. The larvae were identified putatively as autoinfective third-stage filariform larvae, and their presence was fatal. The autoinfective filariform larva of S. stercoralis has not been previously reported in Korea.
粪类圆线虫的自身感染性丝状幼虫可在免疫抑制宿主中引起超感染。在此,我们报告一例男性患者,该患者因呼吸困难入住光州退伍军人医院急诊室,当时正在接受哮喘的皮质类固醇治疗。在巴氏染色痰中检测到许多尾部有缺口的粪类圆线虫细长幼虫。它们的长度为269±21.2微米,宽度为11±0.6微米。食管延伸至体长的近一半。这些幼虫被初步鉴定为自身感染性第三期丝状幼虫,它们的存在是致命的。粪类圆线虫的自身感染性丝状幼虫此前在韩国尚未见报道。
