Abstract

As they can act as intermediate hosts to various parasitic species, snails have a particular veterinary importance. The study was conducted to investigate the histopathological effects of Parapleuro lophocercous larval stages on the digestive glands of M. tuberculata. Snails infected with Parapleuro lophocercous cercaria were collected, and infected digestive glands were isolated and prepared for histological preparation. Histopathological observation in infected snail tissues showed considerable damage to the digestive gland such as lyses necrosis, enlargement of the epithelial layer and separation of connective tissue. The severity of any histopathological damage depends on the type of larval stages and degree of infection.
