Urinary tract infections (UTIs) are one of main health problems caused by many microorganisms, including uropathogenic Escherichia coli (UPEC). The virulence factors important in colonization UPEC, extra-intestinal survival, and creation cytopathic effects. In addition, the expression special UPEC can contribute to uropathogenicity, as well worsening UTIs. this study, 134 isolates E. were colle...

UNLABELLED The first step in the infection of humans by microbial pathogens is their adherence to host tissue cells, which is frequently based on the binding of carbohydrate-binding proteins (lectin-like adhesins) to human cell receptors that expose glycans. In only a few cases have the human receptors of pathogenic adhesins been described. A novel strategy-based on the construction of a lectin...

Problem statement: Omphalitis is one of the most common causes of mortality in chicks during the first week after hatching. Escherichia coli strains are the most common isolated bacteria from omphalitis cases of chickens. Bacterial colonization in the host cells surfaces is a critical first step in the pathogenesis of avian pathogenic Escherichia coli isolates. Thus the current study was undert...

Finished genome sequences are presented for four Escherichia coli strains isolated from bloodstream infections at San Francisco General Hospital. These strains provide reference sequences for four major fimH-identified sublineages within the multilocus sequence type (MLST) ST95 group, and provide insights into pathogenicity and differential antimicrobial susceptibility within this group.

TO THE EDITOR—We read with interest the article by Johnson et al, which demonstrates that, in extraintestinal pathogenic Escherichia coli (ExPEC), fluoroquinolone (FQ) resistance is currently associated with the rapid expansion of a single dominant multidrug-resistant (MDR) strain that emerged within sequence type (ST) 131 [1]. Although the strong predominance of the ST131 clone has been well d...

In this study, virulence factors such as serum resistance, aerobactin iron uptake systems, adhesins (type 1 fimbria, P S afimbrial adhesins), haemolysine, uropathogenic spesific protein and cytotoxic necrotizing factor in 45 Escherichia coli isolates from dogs cats with urinary tract genital system infections, were investigated by both phenotypic methods molecular methods. PCR examinations of E...
