Abstract

The study demonstrated histological changes in stray dogs intestine infected with Toxocara canis, stray dogs collected from different areas in Saladin Governorate, Degeneration appeared in a number of epithelial cells of intestinal villi with desqumation in some of them, presence of many large gaps in mucosal cells lining these intestinal mucous glands with lymphocytic infiltration between the mucous glands and small lymph foci and appearance of dissociation and degeneration on smooth muscle layer of intestinal wall.

Intestinal villi of stray cats infected with Toxocara cati, showed degeneration and dissociation in epithelial cells lining it, with lymphocyte infiltration between mucous glands and small lymphatic foci, signs of degeneration appearing on the smooth muscle layer of intestinal wall and lymphocyte infiltration in serous layer.

The conclude of study that the intestinal tissues of dogs and cats infected with toxocara sp. Affected by the appearance of degeneration of some epithelial cells and desqumation of others and the presence of large gaps in the mucous cells lining these intestinal glands with the spread of lymphocytic infiltration, hyperplasia is one of the important conditions that reflects the pathological effects caused by worm infection.
