Ecology Trichophyton concentricum is an anthropophilic dermatophyte which is primarily isolated from certain peoples from Central America, Oceania, South America, and Central America.
Pathogenicity and Health Effects Trichophyton concentricum is a causative agent of dermatophytosis infection of the glabrous skin which is described by the formation of squamae in concentric and poly - cyclic rings that frequently cover the entire body.
Macroscopic Appearance Ø Rate growth is slow and colonies are glabrous, lightly downy at times; and Ø The surface colony color is white becoming cream, amber or brown while the reverse ranges from white to pink or brown.
Microscopic Appearance Ø Irregular, septate hyphae are present, appear in favic chandeliers at times; and Ø Both macroconidia and microconidia are absent.
