Scedosporium apiospermum infection presenting as a mural urinary bladder mass and focal peritonitis in a Border Collie

Scedosporium apiospermum is an opportunistic mold that is an emerging disease in humans and animals. This report describes a case of S. apiospermum infection inciting a mural urinary bladder mass and focal peritonitis in a dog that had a history of multiple traumatic events several years prior. For diagnosis, culture followed by MALDI-ToF, PCR, and sequencing was performed to accurately identify the species. Susceptibility testing was also performed due to the inherent resistance of S. apiospermum to numerous antifungal agents
