A 73-year-old man living in Kawamata-machi, Fukushima Prefecture, Northeastern Honshu, Japan, visited a hospital with complaints of a subcutaneous swelling that had developed on the back of his left hand. The nodule was surgically removed from the vagina fibrosa tendinis of his left forefinger. Based on the histopathological characteristics, the causative agent of this nodule was identified as a female Onchocerca dewittei japonica (Spirurida: Onchocercidae). The species identification was confirmed by cox1 gene sequencing of the worm tissues from paraffin-embedded sections of the nodule. Although 11 cases of zoonotic onchocercosis have previously been recorded in Kyushu and Western Honshu, Japan, the present findings represent the first human case of infection with O. dewittei japonica in Northeastern Honshu, Japan.
一名73岁男性居住在日本本州岛东北部福岛县川俣町，因左手背出现皮下肿胀前往医院就诊。该结节从其左手食指的腱纤维鞘中手术切除。根据组织病理学特征，该结节的病原体被鉴定为日本德维特盘尾丝虫（旋尾目：盘尾丝虫科）。通过对结节石蜡包埋切片中虫体组织的cox1基因测序，确认了物种鉴定。尽管此前在日本九州和本州西部已记录了11例人兽共患盘尾丝虫病病例，但本研究结果代表了日本本州东北部首例人类感染日本德维特盘尾丝虫的病例。
