[Age-related features of dysbiosis of large intestine].
OBJECTIVE
To compare rate of detection of stage II-III intestinal dysbiosis with normal and decreased quantities of bacteria from Lactobacillus and Bifidobacterium families in different age groups.


METHODS
Microflora of large intestine was studied in 600 persons of different ages with normal quantity or deficit of bacteria from Lactobacillus and Bifidobacterium families.


RESULTS
Decrease of bifidobacteria level in structure of large intestine microflora increases rate of detection of opportunistic microorganisms--predominantly, bacteria from Klebsiella genus and Staphylococcus aureus. Decrease of lactobacilli level had lesser influence on rate of detection of opportunistic microorganisms.


CONCLUSIONS
Results of bacteriologic studies of large intestine microbiocenosis demonstrate that intestinal microflora has its own characteristics in each age group.
