| Popis: | The etiological structure of urinary tract infections (UTI) is determined by the leading role of uropathogenic Escherichia coli (UPEC). The aim of the work is to study the biological properties and phylogenetic diversity of E. coli strains isolated from UTI in outpatient and inpatient patients. METHOD s and materials. 198 clinical UPEC strains were studied, 105 of which were designated as polyclinic and 93 as nosocomial (73 are isolated from urine and 20 are from catheter surface 48 hours after hospitalization). UPEC phylogenetic groups were determined by polymerase chain reaction (quadruplex PCR) according to O. Clermont et al. (2013). RESULTS Among polyclinic cultures, representatives of all eight recognizable phylogroups were found; strains of UPEC phylogroup B2 (37.1%), E (13.3%) and F (8.6%) were most often found. Nosocomial cultures in almost 90% of cases belonged to the phylogroup B2, to which all the catheter-associated strains were assigned. The E. coli of the phylogroup B2, both in the mono-species and in the polymicrobial associations, was authentically more often isolated in the hospital than in the polyclinic (p |
