The Viability of Ringworm Fungi in Dry Cutaneous Material

Abstract

This experiment was conducted to determine in a general way how long these fungi could remain viable in the surplus scrapings, hairs, etc., which had been preserved dry for future use in paper envelops in our laboratory files. The results would also yield some rough idea of how long the material might retain its infectiousness in those articles of clothing (slippers) and the toilet (brushes and combs) which are not always periodically cleansed.

Tinea of the Foot

“…The reason for this disappearance is hard to understand in view of the viability of the pathogenic fungi (Farley, 1921 ;Weidman, 1927a;Bruhns, Alexander, and Kadisch, 1929), but the secondary bacterial contamination which sometimes occurs may in some way exert a lethal influence on the moulds. In this connexion the observations of Weidman (1926) on a case of pedal ringworm sown with yeasts are of importance.…”

Effect of storage temperature on viability of Trichophyton mentagrophytes in infected guinea pig skin scales

“…Many researchers have shown that dermatophytes remain viable at room temperature for extended periods of time in infected skin, hair, and nails (5,8,9,11,13,14,16,17,19). In this study we attempted to determine the effect of storage temperature on the viability of Trichophyton mentagrophytes in infected guinea pig skin scales in a quantitative and controlled manner which was not generally used in previous investigations.…”
