Abstract

An attempt was made to investigate the pathological changes in the intestine of free range scavenging chickens infected with cestodes parasite Choanotenia infundibulum. For the purpose 100 birds (Gallus domesticus) were randomly purchased from different villages and local markets of district Hyderabad, Pakistan. Chicken were dissected and different parts of intestine were searched. Out of 100 birds 94 (89.5%) were found infested with Choanotenia infundibulum. For histopathological examination different parts of infected intestine were fixed in Bouin’s fixative for period of 24 hours. Paraffin embedded tissues were cut 5-6 micron thick and stained with hematoxylin and eosin (H&E). Histopathological findings revealed sever damage including distortion, fusion, inflammation and destruction of architecture of muscular layers, villi and glands. It was concluded that high level of parasitic infestation cause severe health problems in birds and this can lead significant losses of poultry production.
