VIRULENT FACTORS OF OPPORTUNISTIC MICROFLORA OF THE LOWER RESPIRATORI TRACT IN PNEUMONIA
Abstract
In the structure of etiologically significant agents at pneumonias opportunistic microorganisms with acquired pathogenic properties are found in increasing frequency. Acquired factors of virulence of opportunistic microflora of lower respiratory tract in community-acquired pneumonia patients were studied. 820 microbial cultures obtained from the phlegm of patients of pulmonology department of multi profile hospital during 6 years (2005-2010) were studied. Both antibiotic and antiseptic resistance, adhesive properties and antagonism were investigated as well as biofilm formation ability and microflora. The growing level of antibiotic resistance of opportunistic microorganisms was shown in the study, the sensitivity to antiseptics being rather high. It was proved that strains studied had pronounced adhesive properties as well as antagonistic ones. The majority of bacterial cultures separated from the lower respiratory tract are able to form biofilms. The further studying of factors of acquired opportunistic microflora of lower respiratory tract will allow to understand a role of microorganisms properties in development of pyoinflammatory diseases more deeply.
