Species which are pathogenic in dogs include:
- Fusarium sporotrichioides
- Fusarium solani
Clinically affected dogs usually present with ulcerative lesions anywhere on the skin. Paronychia is a common presentation.
In food-borne mycotoxicosis, consumption of grains naturally contaminated with Fusarium mycotoxins can adversely affect dogs' feeding behaviors and metabolism. The main active toxin, zearalenone, is an estrogenic metabolite which causes profound regressive lesions in the ovarian granular cells, leading to degeneration, atrophy and resultant infertility.
A second mycotoxin which has been reported in this species is trichothecene, which reportedly causes primarily gastrointestinal effects such as diarrhea.
Systemic diseases associated with this fungus have been reported, with cutaneous and submucosal nodules and pyogranulomatous kidney lesions.
Central nervous system disease has also been reported, with meningoencephalitis observed.
This dermatophytosis appears to respond to itraconazole.
