To study microbial repertoire of urine in healthy women and patients with chronic recurrent cystitis (CRC) including facultative anaerobic (FA) and non-clostridial anaerobic (NCA) bacteria. MATERIALS AND METHODS. Triple bacteriological study of urine was performed in three groups of women: group I--22 healthy virgin women aged 18- 25 years, group II--24 women aged 18 - 25 years with regular sexual contacts, group III--72 women aged 20 - 60 years with CRC, before antibacterial therapy. Bacteriological method was used to study qualitative and quantitative composition of urine microflora. In all subjects from groups I and II aerobic-anaerobic associations with predomination of coagulase-negative staphylococci (CNS), corynebacteria, peptococci, and peptostreptococci were isolated from urine. Quantity of isolated NCA bacteria was significantly higher than that of FA. In etiologic structure of CRC, NCA bacteria, enterobacteria, and CNS predominated. Spectrum of NCA bacteria isolated from patients with CRC was wider and level of bacteriuria--higher (p < 0.05) compared to groups I and II. Bacteria were identified in aerobic-anaerobic associations. In 85.7% of cases following NCA were identified in biopsy samples: Propionibacterium sp. (41.8%), Peptococcus sp. (35.7%), Eubacterium sp. (28.6%), Peptostreptococcus sp. (14.3%), and Bacteroides sp. (14.3%). Aerobic-anaerobic associations were observed in 7.1% of samples. Urine of healthy women is not sterile. Aerobic-anaerobic mixed infections were detected in patients with CRC that should take into account during diagnostics and treatment of this disease.
