Cross-species convergence of surface polysaccharides shapes the virulence of an atypical carbapenem resistant uropathogenic Escherichia coli clone

Lachlan L. Walker, Zheng Jie Lian, Minh‐Duy Phan…·Mark A. Schembri

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.

Strain level variation in Proteus mirabilis chondroitin sulfate degradation kinetics and regulation by urea

Braden M. Shipman, Zhou Serena, Benjamin C. Hunt…·Nicole J. De Nisco

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.
