Ecology Trichophyton rubrum is the most widespread among the anthropophilic dermatophytes. Anthropophilic dermatophyte is found in association with humans.
Pathogenicity and Health Effects Trichophyton rubrum is the most common agent of tinea of the feet, hands, nails, groin, and the glabrous skin, however, the scalp is rarely infected. Animals are very infrequently infected as well.
Macroscopic Appearance Ø Growth rate is slow to moderately rapid and texture of colonies ranges from downy to powdery; and Ø Surface colony color is white to pale pink while reverse is usually wine red, however at times, the color ranges from red, brown, violet, yellow or even uncolored.
Microscopic Appearance Ø Presence of microconidia is numerous to rare, club – shaped to pyriform, may be found solitary along the hyphae or sometimes in clusters, and are unicellular; and Ø Microconidia are frequently absent; pencil – to cigar – shaped, and are multi - septate. |

Mold in the Bible
Bible at mold contamination, and mold infestation have always been threats to people, animals, and plants. Mold Prevention is always needed. "The way to control indoor mold growth is to control moisture,” reports the U.S. Environmental Protection Agency. To keep indoor humidity in the mold-safe 30-40%, use our Surround Air Dehumidifier. |
