* Diagnostic Center for Population and Animal Health, College of Veterinary Medicine, Michigan State University, East Lansing, MI 48824, USA Non-Tuberculous mycobacteriosis is infrequently reported in frogs and toads. This case report describes a captive marine toad, Bufo marinus, which presented with spontaneous acute fracture of the left tibia. In spite of amputation and antibacterial therapy, this toad continued to decline, so elective euthanasia and subsequent post-mortem examination were performed. Microscopic evaluation of the fracture site and additional organs including one front limb, lungs, heart, liver and kidneys exhibited granulomatous inflammation associated with numerous acid-fast positive bacilli. Mycobacterium marinum and M. terrae were isolated from lung and liver. The toad also had pigmented fungi within granulomas in a number of different tissues, including bone. [Abstract] |
