Eosinophilic meningitis caused by Angiostrongylus cantonensis after ingestion of raw frogs

Abstract

Angiostrongylus cantonensis is the most common cause of eosinophilic meningitis in humans after ingestion of raw or inadequately cooked intermediate hosts or food contaminated with infective third-stage larvae. Frogs are known to be a paratenic host of A. cantonensis, but have never been reported as the infectious source of human angiostrongyliasis in Taiwan. We report the first case of eosinophilic meningitis caused by A. cantonensis after ingestion of raw frogs (Rana plancyi). Copyright © 2007 by The American Society of Tropical Medicine and Hygiene.
