Insights
Infant gut microbiota shows high dysbiosis rates, with Staphylococcus aureus and hemolytic E. coli being common pathogens. This highlights the need for infection control, especially in healthcare settings.
Area of Science:
- Microbiology
- Pediatrics
- Gastroenterology
Context:
- The large intestine's microflora plays a crucial role in health.
- Dysbiosis, an imbalance in gut microbiota, is linked to various health issues.
- Understanding age-related changes in gut microbiota is essential for pediatric health.
Purpose:
- To investigate the dynamic, qualitative, and quantitative alterations of the large intestine's microflora across different pediatric age groups.
- To identify prevalent microbial pathogens associated with dysbiosis in children.
Summary:
- Stool samples from diverse pediatric age groups (0-6 months, 6 months-1 year, 1-7 years, 7-14 years, >14 years) were analyzed for dysbiosis.
- The highest dysbiosis rates (92-100%) were found in infants (0-1 year).
- Staphylococcus aureus and hemolytic Escherichia coli were the predominant pathogens identified in large intestine microbiota pathology throughout the study period (1999-2008).
Impact:
- Findings underscore the vulnerability of infant gut microbiota to dysbiosis.
- Highlights the critical role of Staphylococcus aureus and hemolytic E. coli in pediatric intestinal dysbiosis.
- Informs targeted infection control strategies in healthcare settings, particularly concerning S. aureus carriage in healthcare workers.
Aim:
To study dynamics of qualitative and quantitative changes of microflora of large intestine in different age groups.
Materials And 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.
Conclusion:
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.
