Generalized Tuberculosis in a South American Frog Leptodactylus pentadactylus

Abstract
A frog is described which had chronic visceral tuberculosis for some time before an acute, granulomatous lesion, in which acid-fast bacilli were identified, appeared in the right eye. In the absence of culture of the causative organism, the diagnosis was inferred from the presence of characteristic morphological changes. The disease process is essentially similar to that in man but the systemic effects are much less marked.
