[Sh. flexneri population heterogeneity according to the cellular fatty acid makeup].
The composition of fatty acids in the cells of 100 clones of Sh. flexneri, strain 9054, isolated from a dysentery patient was studied by the method of gas chromatography. Fatty acid composition in 75 clones was similar to the fatty acid composition of the initial culture: 25 clones differed to a variable degree from the prevailing group of clones in the content of unsaturated and cyclopropane fatty acids and, to a considerably lesser extent, in the content of palmitic acid and a number of other saturated fatty acids. After the change of the culture medium (agar and broth) the differences in the fatty acid composition of the clones could still be observed. The data obtained in this study indicate the heterogeneity of Shigella population in the composition of cellular fatty acids.
