Oestrus ovis is a dipteran parasite responsible of myiasis in small ruminants and reported as the causative agent of myiasis in humans particularly in sheep farming areas. In recent years, several human cases had been reported without any previous history of exposure to livestock or visit to rural areas.
We describe three clustered cases of ophthalmomyiasis externa in tourists in Sardinia and Sicily and discuss them in the light of the published literature. The patients presented ocular irritation, foreign body sensation, pain, redness, and lacrimation of the eyelids. After extraction, all the larvae were morphologically and molecularly confirmed as L1 instar of O. ovis larvae.
The present study points out the need to draw attention and awareness among the physicians, and to consider ophthalmomyiasis when consulted for conjunctivitis in the summer and spring seasons.
羊狂蝇是一种双翅目寄生虫，可导致小型反刍动物患蝇蛆病，并且在人类中，尤其在绵羊养殖地区，被报告为蝇蛆病的病原体。近年来，已报告了几例没有任何接触家畜史或前往农村地区经历的人类病例。
我们描述了撒丁岛和西西里岛游客中发生的三例聚集性眼外蝇蛆病病例，并根据已发表的文献进行讨论。患者出现眼部刺激、异物感、疼痛、眼红和眼睑流泪症状。提取后，所有幼虫经形态学和分子学鉴定为羊狂蝇L1龄幼虫。
本研究指出，需要引起医生的关注和重视，在春夏季节诊治结膜炎时应考虑眼蝇蛆病。
