Classification of Mycobacterium farcinogenes and Mycobacterium senegalense by immunodiffusion and thin-layer chromatography of long-chain components


, : Classification of Mycobacterium farcinogenes and Mycobacterium senegalense by immunodiffusion and thin-layer chromatography of long-chain components. Journal of General Microbiology 128(6): 1299-1307

Comparative immunodiffusion studies and thin-layer chromatographic analyses of whole-organism acid methanolysates were performed on 37 strains of Mycobacterium farcinogenes, Mycobacterium senegalense and Nocardia farcinica. The latter were clearly distinguished from the mycobacteria in containing a single mycolic acid methyl ester and showing more precipitinogens with nocardial than with mycobacterial and rhodococcal reference systems. The distribution of precipitinogens showed that M. farcinogenes and M. senegalense were very closely related and that both showed a greater affinity to Mycobacterium fortuitum than to any of the other established species of Mycobacterium tested. The complex pattern of alpha-mycolates and characteristic polar mycolates found in both M. farcinogenes and M. senegalense has only previously been found in M. fortuitum and Mycobacterium smegmatis.
