[Opportunistic microorganisms in respiratory tract diseases in patients of the Moscow Province region].

The respiratory tract microflora in patients with inflammatory processes of the upper and lower respiratory tracts in the Moscow Province region has been studied. Changes in the microflora were found to occur in patients with pyoinflammatory diseases (PID) of the upper and lower respiratory tracts have been found to occur. Gram-positive cocci, mainly staphylococci and streptococci, were shown to play the leading etiological role in the development of PID. As revealed in this study, the microorganisms detected in the inflammations of the upper and lower respiratory tracts are coagulase-negative staphylococci, mainly S. epidermidis, as well as enterococci and streptococci belonging to the group viridans.
