Abstract
Comparison of the cellular fatty acids of 10 strains of Mycobacterium marinum and 35 strains of Mycobacterium kansasii revealed similarities within each species but differences between these two photochromogenic mycobacteria. A branched-chain fatty acid characteristic of M. kansasii was found in trace amounts in 2 of the 10 strains of M. marinum.
