Human bladder 5637 cells cultivated under microgravity conditions formed organoids that displayed characteristics of in vivo tissue-specific differentiation. Uropathogenic Escherichia coli (UPEC) strain CP9 colonized and penetrated the organoids and induced alpha-hemolysin-mediated exfoliation of uroepithelial cells. We propose these uro-organoids as models that simulate the interactions betwee...

Asymptomatic bacteriuria (ABU) is a bacterial carrier state in the urinary tract that resembles commensalism at other mucosal sites. ABU strains often lack the virulence factors that characterize uropathogenic Escherichia coli (E. coli) strains and therefore elicit weak innate immune responses in the urinary tract. In addition, ABU strains are active modifiers of the host environment, which the...

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.

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.

Due to the genetic similarity of pathogenic Escherichia coli isolated from birds and pathotypes human origin, it is suggested that they have a common ancestor may exchange virulence-associated genes. This study aimed detect genes in E. strains Red-browed Amazon parrot (Amazona rhodocorytha) kept at conservation institute Brazil. High variability virulence was observed, since 12 profiles were fo...

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a debilitating syndrome of unknown etiology often postulated, but not proven, to be associated with microbial infection of the prostate gland. We hypothesized that infection of the prostate by clinically relevant uropathogenic Escherichia coli (UPEC) can initiate and establish chronic pain. We utilized an E. coli strain newly isolate...
