Abstract

Macroscopic encysted metacercariae in muscles of Clarias lazera were proved to be the larval stage of Cynodip < /em>lostomum azimi, while the microscopic ones obtained from both Clarias lazera and Tilapia nilotica were found to be those of Prohemistomum vivax. Both parasites were recorded in man. Metacercariae in c.lazera were destroyed by chilling at (4°c) after 72 hours and by freezing at (-10 C) after 24 hours. Metacercariae in Tilapia nilotica were killed after 48 hours chilling and 24 hours freezing. Grilling killed all metacercariae in Tilap < /em>ia nilotica within 15 minutes. 10% citric acid killed metacercariae in T. nilotica within 24 hours but those in C. lazera were killed within 48 hours, 20% citric acid killed metacercariae in both fishes within 24 hours.
