Abstract

Moluscos coletados em cinco localidades no estado do Rio Grande do Sul (Brasil) foram digeridos e examinados. As lesmas infectadas foram identificadas como Phyllocaulis variegatus e as larvas encontradas foram inoculadas per os em camundongos albinos. Após 50 dias, parasitos com as características de A. costaricensis foram recuperados do sistema arterial mesentérico. Estes resultados estabelecem o papel do P. variegatus como hospedeiro intermediário de A. costaricensis no sul do Brasil, onde diversos casos de angiostrongilíase abdominal têm sido diagnosticados.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 abdominla angiostrongyliasis have been diagnosed
