Fifteen, White Leghorn layer chick carcasses and
ve ailing birds aged 4 weeks were presented at
the Department of Veterinary Pathology, Veterinary

chicks exhibited ruf ed feathers, somnolence
and greenish diarrhoea. Grossly, there were
no typical lesions except haemorrhagic bursa.
Histopathologically, there were severe lymphocytic
depletion, central follicular necrosis and
haemorrhages. The bursae samples showing
lesions were positive for AGPT against IBD
known serum. But the typical lesions of IBD
viz. heamorrhage in the thigh, breast muscle,
gizzard - proventriculus junction and renal
