Opportunistic microorganisms in urinary tract diseases

: The microflora of clinical material (urine, urethral discharge and smear, vaginal discharge and smear, feces in colonic dysbacteriosis) from patients with urinary tract infections (UTI) in the Moscow Region was studied. Escherichia coli and Staphylococcus epidermidis have been found to be the most common agents isolated from the urine of UTI patients. Pseudomonas aeruginosa and other staphylococcal species and enterococci account for a smaller proportion of infections. High- (E. coli and S. epidermidis) and moderate-priority pathogens are translocated into the urinary tract from the colonic biotope in dysbacteriosis. The causative agents of non-gonococcal urethritis are staphylococci (more commonly epidermal ones) in 50% of cases, those of pyelonephritis are staphylococci (predominantly E. coli) in more than 50% of cases. The etiological agents of female genital infections are staphylococci (mainly epidermal ones) in 40% of cases.
