N2  - A healthy person’s urine is not a sterile environment, and its microbiota contain a wide range of Gram-positive and Gram-negative aerobic and anaerobic bacteria, with Gram-positive aerobic microorganisms predominating. There are significant differences between the urinary microbiota of healthy men and women. The composition of healthy women’s urinary microbiota depends on age and sexual activity. Non-clostridial anaerobic bacteria (NAB) predominate Enterobacteriaceae in case of acute obstructive pyelonephritis with bacteriuria of 104 CFU/ml and higher. Experiments have shown that obstructive pyelonephritis can be caused by various species of NAB (Peptococcus spp., Bacteroides spp., Eubacterium spp.). In every third case of recurrent symptomatic uncomplicated lower urinary tract infection (UTI) Enterobacteriaceae with low level bacteriuria of ≤103 CFU/ml are found and every third case of acute cystitis is not associated with typical uropathogens. Low levels of bacteriuria (102–103 CFU/ml) correlate with symptoms of upper and lower UTI and thus cannot be considered contamination. Asymptomatic bacteriuria is normal in healthy individuals.
