Abstract
Possible application is studied for fluorescence spectroscopy in the express-evaluation of the gastrointestinal microflora. This diagnostic approach is feasible because of the difference in fluorescent spectra from different microorganisms, with anaerobic microorganisms exhibiting the most pronounced fluorescence. It was found that fluorescence strength raised with an increase in the bacteria Bacteroides and bifid bacteria, whereas it decreased with an increase in Escherichia coli. The bacteria Bacteroides and bifid bacteria are the most typical representatives of anaerobic bacteria, whereas the bacteria Escherichia coli are the typical representatives of aerobic bacteria. According to the literature, Bacteroides and bifid bacteria reveal an intense fluorescence. Bearing in mind that these genera of bacteria play an important role in the gastrointestinal microbiocenosis, fluorescence spectroscopy can be used as a diagnostic means for gastrointestinal dysbacteriosis.
