208 Descriptions of Medical Fungi RG-2 organism. Morphological Description: Colonies are mostly flat to slightly raised, white to cream, suede-like to downy, with either no reverse pigment or a yellow-brown to wine-red reverse. Most cultures show scanty to moderate numbers of slender clavate to pyriform microconidia. Macroconidia are usually absent, but when present are smooth, thinwalled multiseptate, slender and cylindrical to cigar-shaped. Older cultures may show numerous chlamydospores with a few clavate to pyriform microconidia. Note: On primary isolation some cultures may lack reverse pigmentation and fail to produce microconidia. These need to be subcultured onto media like lactritmel agar or potato dextrose agar, which stimulate pigmentation and sporulation. If sporulation still fails subculture the fungus onto Trichophyton agar No.1. Confirmatory Tests: Trichophyton rubrum (Castellani) Semon Littman Oxgall Agar: Raised, greyish-white, suede-like to downy colony with no reverse pigment. Some cultures may show a greenish-yellow diffusible pigment. Lactritmel Agar: Flat, white to rose pink, downy to granular colonies with a deep winered reverse pigment. Sabouraud’s Dextrose Agar with 5% salt: Very stunted, white to cream, downy to glabrous colony with a pale yellow-brown reverse pigment. 1% Peptone Agar: Flat, white to cream, downy to glabrous colony with no reverse pigment. BCP Agar: restricted colony growth and neutral (unchanged) pH. Colonies typically demonstrate red pigment on reverse Hydrolysis of Urea: Typically, negative at 7 days (some may be positive). Vitamin Free Agar (Trichophyton Agar No.1): Good growth indicating no special vitamin requirements. Colonies are flat, white to cream, suede-like to downy with a deep wine-red reverse pigment. Hair Perforation Test: Negative at 28 days. Key Features: Include clinical history, culture characteristics, microscopic morphology and failure to perforate hair in vitro.
Descriptions of Medical Fungi 209 Trichophyton rubrum (Castellani) Semon a b Note: Trichophyton rubrum produces both red and yellow pigments. Culture colours may range from none to dark red to dark yellow, with all combinations in between. The images above show the same strain (a) grown on lactritmel agar that promotes red pigmentation and (b) on mycobiotic agar that shows an underlying yellow pigmentation. 20 µm 20 µm Trichophyton rubrum showing typical slender clavate microconidia.
