Microsporum canis

Microsporum canis is a pathogenic, asexual fungus in the phylum Ascomycota, class Eurotiomycetes, order Onygenales and family Arthrodermataceae, named by E. Bodin in 1902 and found worldwide. It reproduces through two conidial forms, large spindle-shaped macroconidia and small single-celled microconidia, and despite its name its natural host is the domestic cat rather than the dog, though it can also colonize dogs and horses, with long-haired cats often serving as symptomless carriers. In humans and animals it infects the upper dead layers of skin, causing tinea capitis and tinea corporis, ringworm-type infections marked by inflammatory lesions and, in some cases, hair loss. Humans become infected mainly through direct or indirect contact with infected pets.
