Dirofilariasis is a rare zoonotic disease which is commonly caused by two species; and . Humans are accidental dead-end hosts of the parasites, and the infection is mainly asymptomatic. Here, we report the case of a 54-year-old Thai woman who experienced a painful left shoulder nodule and eosinophilia for 1 month. An excisional biopsy of the nodule revealed a degenerated filarial nematode compatible with adult females of the species. Molecular identification of the partial 12 mt rRNA gene of the worm confirmed that the causative species was , a zoonotic filariasis that causes subcutaneous dirofilariasis in dogs and cats. To the best of our knowledge, this was the first reported case of subcutaneous dirofilariasis caused by in Thailand. This increased concerns about zoonotic filariasis from natural animal reservoirs in Thailand.
犬恶丝虫病是一种罕见的人畜共患病，通常由两种丝虫引起，即犬恶丝虫和匐行恶丝虫。人类是这些寄生虫的偶然终末宿主，感染通常无症状。在此，我们报告一例54岁泰国女性病例，该患者左肩部出现疼痛性结节并伴有嗜酸性粒细胞增多1个月。对该结节进行切除活检，发现一条退化的丝虫线虫，与犬恶丝虫的成年雌虫相符。对该虫部分线粒体12 rRNA基因进行分子鉴定，证实病原体为匐行恶丝虫，这是一种人畜共患丝虫病，可在犬猫中引起皮下犬恶丝虫病。据我们所知，这是泰国首例由匐行恶丝虫引起的皮下犬恶丝虫病报告病例。这增加了对泰国天然动物宿主传播的人畜共患丝虫病的担忧。
