angiostrongyliasis

[an′jē·ō·stron′ji·lī′ə·sis]

infection by a species of Angiostrongylus. Infection comes after eating contaminated raw or insufficiently cooked hosts such as snails, slugs, prawns, or crabs. Adult worms live in rat intestines, in which females lay eggs yielding first stage larvae. These larvae hatch and migrate to the rat's pharynx, where they are swallowed and shed in the feces and ingested by an intermediate host, such as snails or slugs. Most cases occur in Southeast Asia and the Pacific Basin. A. costaricensis causes abdominal or intestinal angiostrongyliasis. Abdominal cases have been reported in Costa Rica and occur most commonly in young children. A. cantonensis larvae migrate to the central nervous system and cause eosinophilic meningitis.
