Carbohydrate composition of the isolated cell walls of dermatophytes.
In an attempt to evaluate taxonomic character of sugar composition of dermatophytes, the purified cell walls from 13 species are analyzed on neutral sugar composition by gas liquid chromatography. The results were principally compatible with those obtained by conventional morphological examination. Neutral sugar components of dermatophytes cell walls were mannose and glucose in the ratio of 1:2.7 for Epidermophyton and 1:1.4 for Microsporum. There were two types in Trichophyton, in which the ratios of mannose to glucose were 1:1.6 and 1:3.8. The cases of Trichophyton ferrugineum and Trichophyton mentagrophytes were exceptional. The ratio of the former was 1:1.4, which implied the relation to Microsporum group, and the ratio of the latter was 1:2.3, which was supposed to be the intermediate of two types of Trichophyton group. Albino type cell wall of Epidermophyton floccosum was more rich in glucose than pigmented type one.
