Abstract
Previously, the present authors observed that mycobacterial species showed various patterns of the distribution of radioactive spots in thin-layer chromatography of lipids after uptake of 35 S-methionine. The majority of the species showed their unique patterns for the species. However, M. scrofulaceum, M. gordonae, and M. flavescens showed two or more patterns. Further studies on M. avium, M. intracellulare, M. scrofulaceum, and M. gordonae showed that these organisms shared the same patterns, and that the patterns of the former three were found in those of M. gordonae.
