Abstract:
:Seventy-one strains of 15 species of rapidly growing mycobacteria were studied for their susceptibilities to fatty acids with 2 to 20 carbons by the agar dilution method at pH 7.0. Most mycobacteria other than potential pathogens (Mycobacterium fortuitum and Mycobacterium chelonei) were resistant to saturated fatty acids, except for lauric acid (C12:0) (MIC, 6.25 to 25 micrograms/ml) and capric acid (C10:0) (MIC, 50 to 100 micrograms#ml). M. fortuitum and M. chelonei were substantially insusceptible to these fatty acids. Unsaturated fatty acids with 16 to 20 carbons, except for C20:5, were highly toxic to group IV mycobacteria other than M. fortuitum, M. chelonei, Mycobacterium smegmatis, and Mycobacterium phlei, these being highly resistant to all the unsaturated acids, except for C16:1, C18:3, and C20:5. Introduction of double bonds to C16 to C20 fatty acids caused a marked increase in their activities that depended on the increase in the number of double bonds, at least up to three or four. M. fortuitum and M. chelonei were more resistant to the unsaturated fatty acids (particularly to C20:3 and C20:4) than the other group IV mycobacteria.
