Abstract: Three Carcasses of one month old female Aseel birds were presented for postmortem examination with the clinical history of reduced appetite, loss of weight and sudden death. The postmortem examination revealed gross pathological lesions of infected organs viz., intestine, liver, bursa, and lungs. Small intestine showed creamy-white cylindrical worms in the cluster which almost occluded the lumen. Few fine ribbon-like segmented organisms embedded in the intestinal mucosa were also observed with hemorrhage on the wall of mucosa. Liver showed hepatomegaly with pale areas of necrotic foci, while the bursa appeared edematous and hemorrhagic. Lungs were congested and pneumonic. Morphological examination of these parasites revealed that the cylindrical parasites belonged to the genus Ascaridia, while the segmented organisms belonged to the genus Raillietina. Further microscopic examination of the intestinal contents confirmed the presence of characteristic ova of Ascaridia spp. It was concluded that the co-infection with these parasites might have caused serious fatality in poultry birds.
