Comparative characteristics of microbiota in puropental-inflammatory diseases of the maxillofacial area in children

Purpose: Determination and comparison of the properties of the microbiota of purulent foci in inflammatory processes of the jaws, acute purulent lymphadenitis, adenophlegmons, boils of the maxillofacial area in children. Materials and methods: A sample of 1176 medical records of inpatients was studied. Microbiological research methods were used, including: microscopic, cultural methods and determination of the sensitivity of the isolated pathogen. Results: Streptococcus pyogenes was identified in inflammatory processes of the jaws in 65.6 %; for acute purulent lymphadenitis – in 14.3 %, for boils – in 9.04 %. Staphylococcus aureus was recorded with boils in 82.53 %, with acute purulent lymphadenitis in 38.1 %; with inflammatory processes of the jaws in 2.8 %. The greatest sensitivity of Streptococcus pyogenes in acute inflammatory processes of the jaws and boils was noted to vancomycin (99–100 %), fluoroquinolones (93.3–98 %), beta-lactams (86.6–91 %); for purulent lymphadenitis – to beta-lactams (100 %); the greatest sensitivity of Staphylococcus aureus in acute inflammatory processes of the jaws was noted to aminoglycosides, fluoroquinolones (96 %), for boils – to aminoglycosides (96.2 %), beta-lactams (94. 3 %), linezolid (93.3 %); for lymphadenitis – to beta-lactams (83 %). Conclusion: In purulent-inflammatory diseases of the jaws in childhood, the leading pathogen was Streptococcus pyogenes with a high level of sensitivity to vancomycin, fluoroquinolones, and beta-lactams; for purulent-inflammatory diseases of soft tissues – Staphylococcus aureus with a high level of sensitivity to aminoglycosides and beta-lactams.
