TRS-PCR profiles correlate with polymorphisms of the genomic o454-nlpD region, virulence factors repertoire, and phylogenetic groups among uropathogenic Escherichia coli strains isolated from patients from Lodz region, Poland
Abstract Extraintestinal urinary tract infections are mainly caused by uropathogenic strains of E. coli. UPECs are a heterogeneous group of strains possessing various genes associated with virulence traits. It was demonstrated that changes in the composition of the o454-nlpD region and genetic varia...

| description | Abstract Extraintestinal urinary tract infections are mainly caused by uropathogenic strains of E. coli. UPECs are a heterogeneous group of strains possessing various genes associated with virulence traits. It was demonstrated that changes in the composition of the o454-nlpD region and genetic variation in the mutS-rpoS chromosomal region in ExPEC strains are correlated with their virulence, particularly in those with the pattern III o454-nlpD region and belonging to phylogenetic group B2. In this study, we investigated the presence and distribution of the o454-nlpD genomic polymorphism in our collection of 124 uropathogenic E. coli strains, examining the correlation of o454-nlpD region types with the virulence factors studied. Our findings revealed a positive association between certain virulence factors in UPEC strains and the presence of pattern III in the o454-nlpD region. Additionally, all these strains were classified under phylogenetic group B2. We also showed that the highly pathogenic group of E. coli identified by examining the polymorphism of the o454-nlpD region coincides with the highly pathogenic group of uropathogens we identified in the averaged TRS-PCR analysis. |
