Prevalence of virulence factors among different phylogenetic groups of Escherichia coli isolated from patients with urinary tract infections

الملخص EN

In this study, the biofilm formation, virulence factors and phylogenetic Groups of 42E.

coli isolates isolated from patients with UTI were determined.

It was revealed that (16.7 %) of the isolates were α-hemolytic, (21.4 %) were β-hemolytic while, (61.9 %) were γ-hemolytic.

Additionally, the percentage of biofilm formation was 50 % for both weak and moderate biofilm formation.

The results of molecular detection of virulence gene revealed that afagene was found in (21.21 %), kpsgene was found in (84.84 %), pap gene was found in (6.06 %) and sfagene in (60.60 %) of multi drug resistance isolates.

The phylogenetic group genes (chuA, yjaA, and TspE4.

C2) were found in multi-drug resistance isolates in percentages (72.72 %, 87.87 % and 72.72 %) respectively.

Most isolates were included under the phylogeny group B2 (69.7 %) of all multi drug resistance E.

coli isolates while the percentages of the rest of the groups were A (21.21 %), B1 (6.06 %) and D (3.03 %) of multi drug resistance isolates.
