The paper identifies a new carbapenem-resistant E. coli clone, ST361, associated with UTI and shows its virulence is linked to surface polysaccharides and mobile genetic elements.

This study shows that Proteus mirabilis uses chondroitin sulfate degradation to support growth and colonization in catheterized urinary tract infections.

This study uses optimized urine metagenomic methods to analyze microbial community dynamics in catheterized patients and identifies predictors of transition from asymptomatic colonization to CAUTI.

This study shows that E. coli's L-fucose utilization pathway enhances biofilm formation and antibiotic tolerance in polymicrobial urinary catheter communities involving E. coli, P. mirabilis, and E. faecalis.

This study analyzes the pangenome of Proteus mirabilis to reveal lineage-specific antimicrobial resistance profiles and discordant genotype-phenotype correlations across 1,027 genomes.

This study investigates the role of DusA, DusB, and DusC enzymes in Proteus mirabilis, showing DusB is critical for fitness, biofilm formation, and virulence in urinary tract infections.

This study examines variation in chondroitin sulfate degradation kinetics and urea regulation among Proteus mirabilis strains, finding that urea-sensitive strains show reduced contribution of CS degradation to urovirulence.

This study shows that two putative hyaluronidases in E. faecalis contribute to its pathogenesis in urinary tract infections and bloodstream infections.
