Molluscs collected in five localities in the State of Rio Grande do Sul (Brazil) were digested and examined. The infected slugs were identified as Phyllocaulis variegatus and the larvae found were inoculated per os into mice. After 50 days, worms with the caracteristics of Angiostrongylus costaricensis were recovered from the mesenteric arterial system. The results establish the role of P. variegatus as intermediate host of A. costaricensis in south Brazil, where many cases of abdominal angiostrongyliasis have been diagnosed.
对在巴西南里奥格兰德州五个地点采集的软体动物进行了消化和检查。受感染的蛞蝓被鉴定为杂色叶状蛞蝓，所发现的幼虫经口接种到小鼠体内。50天后，从肠系膜动脉系统中发现了具有哥斯达黎加管圆线虫特征的蠕虫。这些结果证实了杂色叶状蛞蝓在巴西南部作为哥斯达黎加管圆线虫中间宿主的作用，在该地区已诊断出多例腹部管圆线虫病病例。
