摘要：Urinary tract infections are serious health and economic burden for society. Selected bacterial species as Escherichia coli, Klebsiella spp., Proteus spp. are often isolated from patience’s urine samples. We investigated twenty strains Escherichia coli, isolated from urine of 14 patients with different urinary infections, 4 patients with asymptomatic bacteriuria and 2 pregnant women. Distribution of virulence determinants as adhesins, motility, hemolysins, serum resistance and biofilm-forming were investigated phenotypically and with multiplex PCR in correlation. We found that strains poses different combinations of virulence capabilities and the structure statistically most often found is the type 1 pili.
