Interaction of uropathogenic Escherichia coli with host uroepithelium.
Investigation into the pathogenesis of Escherichia coli urinary tract infection has provided numerous insights into the mechanisms by which bacteria adhere, grow and persist in association with host tissue. Many molecular details concerning the interaction of these bacteria with their host have been elucidated, and the murine model of cystitis has generated a new paradigm by which acute and rec...
متن کاملUropathogenic Escherichia coli as a model of host-parasite interaction.
Resistance to mucosal infection varies greatly in the population, but the molecular basis of disease susceptibility is often unknown. Studies of host-pathogen infections are helpful to identify virulence factors, which characterise disease isolates, and successful defence strategies of hosts that resist infection. In the urinary tract infection (UTI) model, we have identified crucial steps in t...
متن کاملThe co‐transcriptome of uropathogenic E scherichia coli‐infected mouse macrophages reveals new insights into host–pathogen interactions
Urinary tract infections (UTI) are among the most common infections in humans. Uropathogenic Escherichia coli (UPEC) can invade and replicate within bladder epithelial cells, and some UPEC strains can also survive within macrophages. To understand the UPEC transcriptional programme associated with intramacrophage survival, we performed host-pathogen co-transcriptome analyses using RNA sequencin...
متن کاملIntracellular Uropathogenic E. coli Exploits Host Rab35 for Iron Acquisition and Survival within Urinary Bladder Cells
Recurrent urinary tract infections (UTIs) caused by uropathogenic E. coli (UPEC) are common and morbid infections with limited therapeutic options. Previous studies have demonstrated that persistent intracellular infection of bladder epithelial cells (BEC) by UPEC contributes to recurrent UTI in mouse models of infection. However, the mechanisms employed by UPEC to survive within BEC are incomp...
متن کاملConditioning of uropathogenic Escherichia coli for enhanced colonization of host.
While in transit within and between hosts, uropathogenic Escherichia coli (UPEC) encounters multiple stresses, including substantial levels of nitric oxide and reactive nitrogen intermediates. Here we show that UPEC, the primary cause of urinary tract infections, can be conditioned to grow at higher rates in the presence of acidified sodium nitrite (ASN), a model system used to generate nitrosa...
