[The etiology of suppurative-inflammatory diseases caused by opportunistic microorganisms at the noninfectious disease clinic].

5,853 strains of opportunistic microorganisms have been isolated from hospitalized patients at a polyclinic. The following microorganisms have been found to cause purulent inflammatory diseases most frequently: Escherichia coli (21.6%), Staphylococcus epidermidis (15.93%), Staphylococcus aureus (14.54%), microorganisms of the genus Klebsiella (11.86%), Pseudomonas aeruginosa (7.91%) and microorganisms of the genus Proteus (7.5%). In cases of mixed infections Gram-negative bacteria prevail. The analysis of microbial species contained in the pathological excreta of patients in different departments has shown the prevalence of staphylococci in general surgery patients, E. coli in peritonitis and gynecological diseases, P. aeruginosa in patients with burns, Klebsiella, Proteus, E. coli, P. aeruginosa in patients with multiple traumatic lesions.
