The genome sizes of the type strains of the sterol-requiring organisms and and of a sterol-nonrequiring obligately anaerobic mollicute, strain 161, were determined by the renaturation method of Wetmur and Davidson. The genome molecular weights of the three strains were almost identical (viz., approximately 10). This value is identical to the genome molecular weights of members of the family in the order and of the family in the order . The guanine-plus-cytosine contents of the deoxyribonucleic acids of , and strain 161, as determined by the buoyant density method, were found to be 30.1, 32.8, and 39.9 mol%, respectively, thereby confirming results reported previously by other workers. The deoxyribonucleic acid base composition and genomic size are among the data needed to clarify the taxonomic status of the genus and of the sterol-nonrequiring anaerobic organism strain 161.
