Myocardial Necrosis Associated with Clostridium novyi Infection in a Bighorn Sheep ( Ovis canadensis ).

We describe a case of myocardial emphysema and necrosis in a bighorn sheep ( Ovis canadensis ), associated with infection by Clostridium novyi , diagnosed through necropsy, histopathology, and fluorescent antibody testing. We documented rapid onset of disease in an apparently healthy wild sheep and discuss our findings in the context of reported clostridial infections in humans, domestic animals, and wildlife.
