ABSTRACT: A 10 yr old broad-snouted caiman Caiman latirostris from a small Dutch animal park was presented with long-term variable periods of anorexia and weight loss. Blood chemistry showed slightly elevated uric acid levels and low ionised calcium concentration. Ultrasonographical thickening of the intestinal wall in the region of the duodenum was evident. Pathological changes were a thickening of the wall of 90% of the small intestines, enlarged spleen with multifocal white foci and an enlarged light-brown liver. Histopathological lesions consisted of disseminated granulomas in the intestinal wall, the liver and the spleen. Multinucleated giant cells and epitheloid macrophages were abundant. Ziehl-Neelsen staining showed numerous intralesional acid-fast bacteria. Polymerase chain reaction for Mycobacterium intracellulare was positive.
