|Description:||This Petri dish culture plate contained an unknown growth medium, upon which grew a single colony of the dermatophytic organism, Microsporm canis. This was an atypical strain, for while M. canis usually gives rise to colonies that are cottony, or wooly in texture, this strain gave rise to a glaborous, or smooth, colonial morphology. See PHIL 15472, for a microscopic view of the M. canis microorganism, and 15474, for a view of a typical wooly textured morphology.|
M. canis, a zoophilic dermatophyte often found in cats and dogs, is a common cause of tinea corporis and tinea capitis in humans. Other dermatophytes are included in the genera Epidermophyton and Trichophyton.
