Fungal diseases

This chapter relates to fungal infections as well as yeast and algae-related diseases in dogs.

Fungi commonly cause superficial skin diseases in dogs but are responsible for severe and often fatal systemic infections. The most common and least pathogenic fungus which affects cats is Microsporum canis, causing ringworm.

Dogs with immune-mediated hemolytic anemia or other causes of immunosuppression (e.g. long-term cyclosporin use) have a greater predilection for systemic disseminated disease.
