In recent decades, the etiological structure of infectious complications in surgery has remained almost unchanged. The aim of this study is to identify the leading pathogens of odontogenic infectious and inflammatory diseases of the maxillofacial area in patients. Materials and methods. The study involved 137 patients with odontogenic infectious and inflammatory diseases of the maxillofacial area. The final species identification of microorganisms was performed according to the generally
... he generally accepted method. Results. 117 clinical strains of microorganisms were isolated from patients and identified. It was found the most common causative agents of odontogenic infectious and inflammatory diseases of the maxillofacial area in patients were gram-positive cocci. It should be noted that the vast majority of isolates were members of the genus Staphylococcus. Gram-negative microorganisms were detected in patients much less frequently (31.6%) compared with gram-positive. In 5.1% of case, C. albicans acted as the dominant pathogen in the material taken from patients with purulent diseases. It was found out that during the development of the abscess, the microbiota were more diverse, but the percentage of pathogens differed significantly with the selection of S. aureus, A. baumannii and E. faecalis as the main ones. In turn, with the aggravation of the infectious process and the development of phlegmon and mediastinitis in patients, a decrease in the spectrum of microorganisms in the studied materials was observed, along with an increase in their percentages. Conclusions. The etiological structure of microbiota of odontogenic infectious-inflammatory diseases of the maxillofacial area is predominantly represented by opportunistic microorganisms of the genera Staphylococcus, Enterococcus, Acinetobacter and Pseudomonas. In general, gram-positive cocci and non-fermenting gram-negative bacteria are the dominant causative agents of odontogenic infectious-inflammatory diseases of the maxillofacial area in most surgical patients.
