Abstract

A female racing homer was brought for a necropsy with a clinical history of vomiting blood-tinged fluid followed by sudden death. The major gross lesions observed during the necropsy were numerous nematodes in proventriculus, gizzard and intestine and haemorrhages in the intestine. The nematodes were identified as Ascaridia columbae. On the histological examination, the intestine revealed atrophy of the villi, necrotised and desquamated mucosal epithelium, infiltration of mononuclear cells in the lamina propria and muscular layer along with haemorrhage. The lungs exhibited multifocal congestion, haemorrhages and dilatation of the parabronchial lumen. The liver showed dilation of the hepatic sinusoids, multifocal haemorrhages and scattered areas of hemosiderin deposition and multiple multinucleated giant cells
