A Curious Case of Blastomyces Osteomyelitis.

Blastomycosis is an uncommon disease caused by the dimorphic fungus, Blastomyces dermatitidis, often found in endemic regions of Midwestern America. It can be found in forested, sandy soils, decaying vegetation, rotting wood near water sources, and even in bird feces. Most commonly, blastomycosis manifests as a pulmonary infection presenting as pneumonia, or in severe cases, respiratory distress syndrome (ARDS).

Chronic intermittent diarrhea in a 14-month-old Abyssinian cat.

A 14-month-old intact, female Abyssinian cat was presented for chronic intermittent diarrhea and bilateral enlargement of the mammary glands. Gastrointestinal coccidiosis was diagnosed; therapy with sulfadi-methoxine was unsuccessful in the elimination of Isospora felis and clinical signs. Infection with Tritrichomonas foetus was diagnosed by fecal polymerase chain reaction (PCR) and successfully treated with ronidazole and dietary modification.
