Introduction: Urinary tract infection is a common nosocomial infection that has recently become difficult to treat because of the increased emergence of multi-drug resistant strains. This study aims to determine the minimum inhibitory concentration, and molecular pattern of resistance to fosfomycin in Escherichia coli isolates originated from patients hospitalized with urinary tract infection i...

Emergence of antimicrobial resistance amongst uropathogenic Escherichia coli and Klebsiella pneumoniae has become a major public health concern of the 21st century [1]. According to World Health Organization (WHO) report 2014, alarming rates of resistance have been reported in all WHO regions due to resistant pathogens like E. coli, K. pneumoniae and Staphylococcus saprophyticus causing urinary...

Urinary tract infection (UTI) is the second most common infection in community practice. It defines as to presence of bacteria in urinary tract, urinary bladder, urine collecting tubes and kidney. UTI causing organisms are mostly human intestinal commensals. These organisms showed virulent behaviors upon transmission to clinically significant biological sites. These organisms includes, Gram Neg...

Cytolysin A (ClyA) of Escherichia coli is a pore-forming hemolytic protein encoded by the clyA (hlyE, sheA) gene that was first identified in E. coli K-12. In this study we examined various clinical E. coli isolates with regard to the presence and integrity of clyA. PCR and DNA sequence analyses demonstrated that 19 of 23 tested Shiga toxin-producing E. coli (STEC) strains, all 7 tested enteroi...

PapG is the adhesin at the tip of the P pilus that mediates attachment of uropathogenic Escherichia coli to the uroepithelium of the human kidney. The human specific allele of PapG binds to globoside (GbO4), which consists of the tetrasaccharide GalNAc beta 1-3Gal alpha 1-4Gal beta 1-4Glc linked to ceramide. Here, we present the crystal structures of a binary complex of the PapG receptor bindin...

The thermally triggered release of up to 96% of attached uropathogenic E. coli is achieved on two polymers with opposite changes in surface wettability upon reduction in temperature. This demonstrates that the bacterial attachment to a surface cannot be explained in terms of water contact angle alone; rather, the surface composition of the polymer plays the key role.

background:urinary tract infections (utis) are the most common infectious diseases in childhood. the uropathogenic escherichia coli (upec) strains account for as much as 80% of utis. objective:from a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in upec strains in pediatrics. therefore, this study was carried out to invest...

Bacteriophage St11Ph5 was isolated from a sewage sample on a particularly phage-resistant uropathogenic Escherichia coli (UPEC) up11 host strain. It appeared to be closely related to bacteriophage G7C, isolated from horse feces; however, it carries a highly divergent host recognition module.

Escherichia coli (E. coli) is a very diverse bacterial species found naturally in the intestinal tract of humans and many other animal species. Even though E. coli is known to be part of the normal gut microbiota, some strains – that are pathogenic – cause a wide variety of different intestinal and extraintestinal diseases (Marrs et al., 2005). Typical extraintestinal infections due to E. coli ...
