The current investigation was undertaken to study the intestine histopathologies due to infestation of helminth parasite cestode, Caryophyllaeus laticeps (Pallas, 1781) in the Cyprinus carpio. Only symptomatic samples of diseased fishes comprised of juvenile and adults of common carp were collected and were patho-anatomical examined. The significant histopathological changes were observed in the intestine where the scolices attached, the vacuolization of the epithelial cells and rupture of the brush border and severe edema. Hyperplasia of the goblet cells and infiltration of inflammatory cells in lamina propia and its epithelium was desquamated in the infested silver carp. No changes were noticed in other organs of the affected fishes. In severe infestations the fishes showed growth retardation and mortality. Thus, it is clear that the endoparasites inhibiting intestine of C. carpio produced pronounced pathological changes in host tissue, all denoting impairment of intestinal physiology.
