By using a panel of 603 commensal and pathogenic Escherichia coli and Shigella isolates, we showed that mutation rates of strains vary considerably among different ecotypes. Uropathogenic strains had the highest frequency of mutators, while strains from patients with bacteremia had the lowest mutation rates. No correlation between the mutation rates and antibiotic resistance was observed among ...
We present here the full-genome sequence of Escherichia coli K-15KW01, an extended-spectrum-β-lactamase-producing uropathogenic strain. Assembly and annotation of the draft genome resulted in a 5,154,641-bp chromosome and revealed a chromosomally contained blaCTX-M-15 gene embedded at the right-hand extremity of an ISEcp1 element in a plasmid-like structure (36,907 bp).
Introduction: Urinary tract infection (UTI) caused by E coli is one of the most common diseases in community. Colonization of E. coli and its attachment to the uroepithelium are mediated by adhesions such as P, Fim and S fimbriae. The present study was aimed to evaluate the prevalence of fimbrial virulence genes in Escherichia coli (E. coli) isolates from the patients with urinary tra...
INTRODUCTION Urinary tract infection is the most frequently diagnosed kidney and urologic disease, and Escherichia coli is by far its most common etiological agent. Uropathogenic E. coli are responsible for approximately 90% of urinary tract infections seen in individuals with ordinary anatomy therefore, it is essential to review the antibiogram of uropathogenic E. coli periodically to help cli...
Fimbrial adhesion is a Virulence Determinant which is classified under Adhesins category of virulence factor of uropathogenic Escherichia coli. Afimbrial adhesin Protein with swissprot accession number P12730, of length 181 amino was selected for modeling using Bioinformatics tools. Modelled protein has been submitted to protein model database and has been assigned an accession number of PM0075...
Urinary tract infection (UTI) is one of the most frequently acquired bacterial infections and Escherichia coli accounts for as many as 90% of all UTIs seen among ambulatory populations. Risk factors for UTIs include host behaviors, host characteristics and bacterial characteristics. Sexual activity and contraceptive method are the strongest determinant of a symptomatic UTI episode. The characte...
α-haemolysin (HlyA)-producing Escherichia coli commonly inflict severe urinary tract infections, including pyelonephritis, which comprises substantial risk for sepsis. In vitro, the cytolytic effect of HlyA is mainly mediated by ATP release through the HlyA pore and subsequent P2X1/P2X7 receptor activation. This amplification of the lytic process is not unique to HlyA but is observed by many ot...
Here, we report the draft genome sequence of a clinical isolate of the uropathogenic strain Escherichia coli KL53. A total of 5,083,632 bp was de novo assembled into 170 contigs containing 89 RNAs and 5,034 protein-coding genes. Remarkable is the presence of the tellurite resistance (ter) operon on a plasmid.
This study was intended to investigate the effectiveness of static magnetic field on the growth of Escherichia coli (E. coli) provided from two sources, the urine samples of patients with urinary tract infections and the reference strain E. coli ATCC 25922. Bacterial samples in Nutrient Broth were subjected to a range of magnetic intensities (2, 4, 6, 9, 14, 16, 18, and 20 mT) at various exposu...
Objective(s): Escherichia coli strains are common pathogens that can cause urinary tract infections (UTI). This study aimed to assess E. coli phylogroups and virulence types in male and female UTI patients.Materials and Methods: In the present study, 160 uropathogenic E. coli (UPEC) isolates (from both sexes) were assigned to phylogroups/types and some extraintestinal virulence factors were det...
