Abstract
Comparing all the results obtained, it appears that the amino acid composition of the 3 dermatophytes examined. T. mentagrophytes, T. schonleinii, and T. rubrum, does not differ neither qualitatively nor significantly quantitatively. Even molds which are not pathogenic for man, such as Penicillium, C. herbarum and Fusarium, show the same amino acid spectrum. There is, however, a striking analogy between the nitrogen levels and the albumen obtained in the only species of Penicillium and the levels of these substances found in dermatophytes. This fact shows that there is a close relationship in their ancestry. T. mentagrophytes, rich in microconidia, gives the highest level of phenylalanine. This fungus is alone in producing a compound which appears to be a-aminobutyric acid. T. schOnleinii, whose culture has a waxy appearance, is especially rich in tyrosine and methionine compared with the other dermatophytes. Further clarification will be necessary for it to be known if this be a characteristic of the favic form. T. rubrum, rich in hyphae, and, because of this, rich in cytoplasm, contains the largest amount of lipids. The large amounts of glycosamine found in the dermatophytes cannot be explained only by admitting that this substance originates in cell walls cells because it can also be produced by cytoplasm.
