[Features of etiologic structure and factors of persistence of bacteria isolated during infection of lower urinary tract and chronic bacterial prostatitis].

AIM: Evaluate microbial specter and factors of persistence in facultative anaerobic bacteria isolated from urine during infection of lower urinary tract (ILUT) and secretion of prostate gland (SPG) during chronic bacterial prostatitis (CBP).

MATERIALS AND METHODS: Bacteriologic study of urine from 144 women (group I) during exacerbation of uncomplicated ILUT and SPG of 105 patients with CBP (group II) was carried out. Quantitative and qualitative composition of microflora as well as adhesive (AA) and anti-lysozyme (ALA) activity for entero-, coryneformic bacteria and hemolytic staphylococci was determined.

RESULTS: In groups I and II aerobic-anaerobic associations with domination of non-clostridial anaerobic bacteria, coagulase-negative staphylococci (CNS), coryneformic bacteria, for urine--enterobacteria were isolated from urin and SPG. S. haemolyticus strains predominated in the CNS group. In group I the frequency of detection of strains of enterobacteria and S. haemolyticus with high AA and ALA were higher (p < 0.05) compared with corynebacteria. In group II cultures of S. haemolyticus more frequently (p < 0.05) had AA and ALA compared with entero- and corynebacteria.

CONCLUSION: In etiologic structure of ILUT and CBP a tendency of shift of gram-negative flora to gram-positive is observed. Detection of AA and ALA in most of the S. haemolyticus and coryneformic bacteria gives evidence of their pathogenic and persistence potential.
