Abstract

Mycobacterial infection in Nile crocodile tissues sent from a private zoo was characterized pathomorphologically and immunohistochemically in this case. Macroscopically, multifocal, greyish-white areas ranging in size from 1 mm to 5 mm were seen in the lung, liver, and spleen. Histologically, a large number of well-demarcated necrotic areas were seen. These areas included nuclei debris locally. Inflammatory cells along with a couple of multinucleated giant cells surrounded the necrotic cores. Numerous acid-fast bacilli were detected by Ziehl-Neelsen staining method. Immunolabelling for both Mycobacterium bovis and anti-BCG antibodies was positive in each tissue.
