Histopathology of Centrorhynchus globirostris (Acanthocephala: Centrorhynchidae) infecting the intestine of the pheasant crow, Centropus sinensis (Stephens) in Pakistan

چکیده
The tissue pathology of the intestinal lining of a pheasant crow (Centropus sinensis) invaded by an acanthocephalan (Centrorhynchus globirostris) was studied from prepared slides. Prominent histopathology was evident viewing the infected tissue. There is extensive damage to the intestinal layers of the pheasant crow initiated by the multi hooked proboscis of the worm. The worm would often work its way into the outer smooth muscle layers of the intestine (muscularis externa) causing host cell necrosis, hemorrhaging and obstruction of the inner mucosal layer. Results of the worm invasion included necrosis of the host epithelial cells, blood loss with pools of nucleated red cells and granular cells outside the capillary walls, and decreased potential for host absorption of nutrient products. An invasion of this worm would definitely affect the absorption capabilities of necessary metabolic products for host life.
