Abstract

In 2017, we investigated a mortality event of muskrat (Ondatra zibethicus) in northwest Ohio, US, and determined the causes of death to be from Tyzzer's disease due to Clostridium piliforme and Klebsiella pneumoniae septicemia. The gross presentation resembled tularemia, which highlighted the importance of a complete diagnostic investigation.
