Sub acute fowl cholera caused by Pasteurella organism was diagnosed in layer flock of Vanaraja bird from an instructional farm experiencing mortality with 17% morbidity. Clinical signs included were of ruffled feather, weakness, dullness with mild conjunctivitis. Upon necropsy generalized congestion of carcass and enlarged liver with multiple necrotic foci measuring 1-2mm size were seen covering whole liver parenchyma and in the other viscera like heart and kidney showed petechial haemorrhage. Microscopically there were hepatocytic necroses with bacterial colonization, damaged nuclear materials and necrosis of the glandular epithelium of intestine with abundant infiltration of heterophils. The severity of congestion and haemorrhages were observed in viscera with decreasing order in the organ’s liver, lungs, intestine, lymphnode and cardiac muscles. The gram negative Pasteurella organism was isolated from liver and heart blood and also demonstrated in other visceral organs when stained with Brown and Breen method of tissue staining. Occurrence of fowl cholera in Vanaraja birds is put on record
