title: [Thin-layer chromatography of mycolic acids methanolysates of whole-cell in Mycobacterium and related bacteria].
abstract: Mycolic acid methanolysates of whole-cell in Mycobacterium and related bacteria were analysed by thin-layer chromatography. The experimental results show that five of twenty-two species, M. tuberculosis, M. bovis, M. kansasii, M. marinum and M. gastri have similar pattern of mycolates, composed of alpha-mycolates, methoxymycolates, ketomycolates and two unknown components. M. gilvum, M. phleri, M. avium, M. intracellulare, M. xenopi and M. nonchromogenicum contain alpha-mycolates, ketomycolates and wax-ester. The patterns of TLC for other tested species were different from each other. Nocardia, Rhodococcus and Corynebacterium show a relatively simple pattern which principally contain alpha-mycolates. The four genus can be differentiated. Spots of mycolic acids of nine strains Mycobacterium sp. isolated from patients in this hospital were similar to M. tuberculosis. These strains were also identified to the same result as above by traditional methods. The method is of value in the classification and identification of Mycobacterium.
