title: [THE CHROMATOGRAPHY-MASS SPECTROMETRY ANALYSIS OF MICROBIAL FATTY ACIDS IN HUMAN BIOLOGICAL FLUIDS AND THEIR CLINICAL SIGNIFICANCE].
abstract: The technique of mass-spectrometric microbial markers is known for almost 20 years. The technique is described in a number of research publications, dissertations and methodological literature. It passed the registration in Roszdravnadzor and is permitted for implementation as a new medical technology in medical institutions on the territory of the Russian Federation ("The evaluation of microecological human status using technique of mass-spectrometry" license FS No 2010/038 of 24.02.2010). The technique of mass-spectrometric microbial markers began to be developed as instrument of clinical routine analysis and monitoring of microecological status, infection and disbiosises in clinical and out-patient practice. The description of technology of mass- spectrometric microbial markers in this aspect requires different than before approach to introduction of clinical laboratory assistants and physicians into technique application. The substantiation given concerning species specificity of composition of fatty acids and (fatty) aldehydes of cellular wall of microorganisms as a basis of their species differentiation in pure culture. The choice is explained concerning molecular markers for their detection in blood and other clinical material with the purpose of further reconstruction of composition of human microbial cenosis (microecology) on blood or calculation of composition of mixed infection in organs om samples of inflammation focus--urine, liquor, phlegm, exudate, drainage, and similar samples containing chemical information about microbes.
