Медико-экологические аспекты микросимбиоценоза человека

Медико-экологические аспекты микросимбиоценоза человека

Abstract

Aim of the study: to assess behaviour reactions of bacteria-associants under conditions of microsymbiocenosis on the model of microflora from human mucosal membrane of the tonsils. Methods: hierarchic structure of microsymbiocenosis was estimated according to the number, informativity and direction of the given signals by strains-symbionts on the modification of the factors of pathogenicity. Regressive equations were obtained by the least squares method. For the prognostication of infectional process of functional biocenosis state coeffcient (Fbsc): proportion of the number of signals on the increase and suppression of the factors of the pathogenicity has been calculated. Results: Strains-symbionts with a high, mean and low levels of communicative activity have been differentiated. According to the level of Fbsc, bacterial carriage, recurrence of the disease and dysbiosis in healthy persons are prognosticated. Conclusions: Structural-and-functional analysis of microsymbiocenosis allows to determine microbial ierrharhia and to prognosticate a course of the infectious process.

Целью исследования явилась оценка поведенческих реакций бактерий-ассоциантов в условиях микросимбиоценоза на модели микрофлоры слизистой оболочки миндалин человека. Иерархическая структура микросимбиоценозов оценивалась по числу, информативности и направленности отданных штаммами-симбионтами сигналов на модификацию факторов патогенности. Получены регрессионные уравнения методом наименьших квадратов. Для прогноза инфекционного процесса рассчитан коэффициент функционального состояния биоценоза (Кфсб): соотношение числа сигналов на усиление и подавление факторов патогенности. Дифференцированы штаммы-симбионты с высоким, средним и низким уровнями коммуникативной активности. По уровню Кфсб прогнозируется резидентное бактерионосительство, рецидив заболевания и дисбиоз у здоровых лиц. Структурно-функциональный анализ микросимбиоценоза позволяет определять микробную иерархию и прогнозировать течение инфекционного процесса.
