Abstract
Third-stage larvae of Angiostrongylus cantonensis recovered from land snails (Achatina fulica) and freshwater prawns (Macrobrachium rosenbergi) which had been exposed at 0 C for 24 hr. were found infective when fed to rats. The larvae, however, were not infective when recovered from snails or prawns which had been exposed in a freezer for 12 or 24 hr. at -15 C. Some of the larvae recovered from snails that had been boiled in water for 1 min. were infective to rats, but larvae recovered from snails boiled for 2 or 3 min. or from prawns boiled for 1 min. were not infective. The thermal death point of the third stage larvae in water has been found to be somewhat between 50 and 55 C.This publication has 1 reference indexed in Scilit:
