The condition of the bird deteriorated after needle aspiration for cytological examination. The budgerigar was euthanatized and a complete necropsy was performed. Microscopic sections were prepared and stained with hematoxylin and eosin, Gram staining, periodic acid-Schiff (PAS) and acid-fast staining. Escherichia coli was isolated in pure culture. Necropsy revealed the pres­ence of granulo­matous lesions of varying sizes at different locations and hepatomegaly, oviduct impaction and oophoritis. Histopathologically, typical granuloma with a central area of coagulation necrosis and bacterial colonies surrounded by lymphocytes, macrophages and multinucleated giant cells were found. These granulomas were present in the liver, oviduct and intestinal tract. A sheet of neoplastic cells and disruption of the normal hepatic architecture was seen. The diagnosis was lymphoid leucosis and coligranuloma. UR - https://ijvm.ut.ac.ir/article_22663.html L1 - https://ijvm.ut.ac.ir/article_22663_a96837dbb2b118af44bc4cbcbf5b6bef.pdf ER -
