|Description:||Depicted in this image was a Petri dish culture containing tissue culture medium 199, upon which was grown colonies of Corynebacterium minutissimum bacteria. The culture plate was viewed under the illumination of a Wood’s lamp, after 24 hours of incubation. See PHIL 12611 and 12612, for two pictures depicting a patient with a bilateral inguinocrural erythrasma infection, both before, and after treatment.|
The bacterium C. minutissimum, is associated with erythrasma, a skin disorder usually involving areas of the skin where one finds skin-to-skin contact, i.e., intertriginous regions. This malady is most prevalent in humid, moist areas of the World, and begins as a spreading, reddish rash, which turns a brownish color, then dries, causing the sloughing of flaking skin.
