Mycobacterium intracellulare infection in a capybara (Hydrochoerus hydrochaeris)

Abstract

This report describes the first case of Mycobacterium intracellulare infection with typical granulomatous lesions of mycobacteriosis in a capybara (Hydrochoerus hydrochaeris). The individual was a captive-bred young female, part of the control group of an experimental study on stress. Multiple granulomatous lesions were detected in a mesenteric lymph node of this young female. We confirmed mycobacterial infection by bacteriological culture and molecular identification methods. Clinical lesions were characterized by histopathology.
