Для взятия проб использовали методы смывов, прямого посева, мембранной фильтрации, инструментальный аспирационный метод. Микробный статус анализировали культуральными и биохимическими методами на питательных и дифференциально-диагностических средах с видовой идентификацией с помощью микробиологического анализатора.

Выполнены микробиологические исследования воздуха и объектов внутренней среды помещений учреждений здравоохранения 2-го класса чистоты (стоматологических кабинетов) для установления качественного и количественного состава микробиоты. По результатам таксономической идентификации установлено, что наиболее распространенными микроорганизмами воздуха являются бактерии рода Staphylococcus, Micrococcus и Kocuria, являющиеся постоянными обитателями кожных покровов человека.</p></sec><sec><title>Заключение</title><p>Заключение.
