title: [Effect of hydroxylamine hydrochloride on lipopolysaccharide fatty acid composition in Shigella dysenteriae 1].
abstract: Changes in the fatty acid composition of S. dysenteriae 1 lipid A after the treatment of lipopolysaccharide (LPS) with hydrosylamine hydrochloride (HH) and 4 degrees C, 37 degrees C and 56 degrees C were studied with the use of gas-liquid chromatographicmass-spectrometry. The treatment with HH led to a decrease in the toxicity of LPS, but produced no changes in the content of the main fatty acid components of lipid A (lauric, myristic, oxymyristic and palmitic acids). At the same time the total number of minor fatty acid derivatives decreased from 11 (in the original LPS) to 5 in LPS treated with HH at 56 degrees C.
