Intracellular Free Amino-Acids of Certain Dermatophytes

Abstract

THE identification and classification of the dermatophytes is dependent on macroscopic and microscopic morphological characteristics developed during growth on standard media. The formulation of biochemical tests to assist in identification would be of considerable value. The work of Mattick et al. ¹, which showed that extracting cells of various species of Lactobacilli with 10 per cent acetic acid removed a mixture of amino-acids and peptides from the cells which was characteristic for each species and constant for strains within a species, suggested the application of a similar technique for the identification of dermatophyte species.
