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 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.

The paper identifies a catecholamine-independent lipolysis pathway activated by hypoglycemia and hypoinsulinemia that enables catabolism of stable adipose tissues.

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