title: [Characteristic of gut microorganisms abnormalities].
abstract: OBJECTIVE
  To study dynamics of qualitative and quantitative changes of microflora of large intestine in different age groups.
  
  
  METHODS
  Stool samples from children of different age groups (0 - 6 months, 6 months - 1 year, 1 - 7 years, 7 - 14 years, >14 years) were tested on dysbiosis.
  
  
  RESULTS
  Majority of patients admitted during the period of 1999 - 2008 were children 1 - 7 years old (32 - 38%). The highest rate of dysbiosis was observed in infants (92 - 100%). Leading place in pathology of microbiota of large intestine during all study period belonged to Staphylococcus aureus and hemolytic Escherichia coli.
  
  
  CONCLUSIONS
  In Karachaevo-Cherkessk republic tightening of measures for surveillance on infection control regime in health-care organizations as well as on carriage of S. aureus in health-care workers are needed.
