DIFFERENTIATION BETWEEN MYCOBACTERIUM KANSASII AND MYCOBACTERIUM MARINUM BY 

 C AS-LIQUID CHROMATOGRAPHIC ANALYSIS OF CELLULAR FATTY ACIDS. Thoen, C. 0., Karlson, A. G., 

 Ellefson, R. D. Applied Microbiology, Vol. 24, Dec, 1972. pp. 1009-1010. (Abstract of Published Report) 



The tatty acid methyl esters extracted from cells of 10 strains of Mycobacterium marinum were analyzed by 

 gas-liquid chromatographic analysis. The fatty acid profiles of each of the strains included saturated fatty acids ranging 

 from Cg to C 2 4 plus some unsaturated analogues and a fatty acid tentatively identified as tuherculosteric acid. A 

 comparison of the cellular fatty acid profiles of strains of M. marinum and of 35 strains of M. 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 only trace amounts in two of the 10 strains of 

 M. marinum.
