Angiostrongylus costaricensis is a nematode parasitic of rodents. Man may become infected by ingestion of the third stage larvae produced within the intermediate hosts, usually slugs from the family Veronicellidae. An epidemiological study carried out in a locality in southern Brazil (western Santa Catarina State) where these slugs are a crop pest and an important vector for A. costaricensis has documented for the first time the natural infection of Deroceras laeve with metastrongylid larvae. This small limacid slug is frequently found amid the folds of vegetable leaves and may be inadvertently ingested. Therefore D. laeve may have an important role in transmission of A. costaricensis to man.
哥斯达黎加管圆线虫是一种寄生于啮齿动物的线虫。人类可能因摄入中间宿主体内产生的第三期幼虫而感染,这些中间宿主通常是扁蛞蝓科的蛞蝓。在巴西南部(圣卡塔琳娜州西部)的一个地区进行了一项流行病学研究,在该地区这些蛞蝓是农作物害虫且是哥斯达黎加管圆线虫的重要传播媒介,首次记录了光滑双脐螺被后圆线虫幼虫自然感染的情况。这种小型的蛞蝓经常出现在蔬菜叶子的褶皱中,可能会被无意中摄入。因此,光滑双脐螺可能在哥斯达黎加管圆线虫向人类的传播中起重要作用。
