A HISTOPATHOLOGIC STUDY OF LYMNEA AURICULARIA VAR RUFESCENS INFECTED WITH THE LARVAL STAGES OF ECHINOSTOMA REVOLUTUM

Abstract

The histopathology of Lymnea auricularia var rufescens parasitized by the larval stages of Echinostoma revolutum was studied. The location of different stages and their induced effects on various organs including the noticeable changes around encysted metacercariae are described. The path of invasion was found to be through lymphatics. Development of the precercarial stages in the muscles of foot and mantle wall was observed.
