Abstract

DNA was extracted and purified from 55 dermatophyte isolates representing 34 species of and The base compositions of the chromosomal DNA were determined by CsCl density gradient centrifugation and were found to be in the narrow range of 48·7 to 50·3 mol % G + C. A satellite DNA component assumed to be of mitochondrial origin was present in most strains, with a G + C content ranging from 14·7 to 30·8 mol % G + C. Heterogeneity in microscopic and colonial characteristics was not reflected in differences in the mean G + C content of the chromosomal DNAs. Strains varied in the G + C contents of satellite DNA, but these did not correlate with traditional species concepts.
