The Pla surface protease of Yersinia pestis activates human plasminogen and is a central virulence factor in bubonic and pneumonic plague. Pla is a transmembrane -barrel protein and member of the omptin family of outer membrane proteases which requir

The O-antigen of lipopolysaccharide (LPS) is a virulence factor in enterobacterial infections, and the advantage of its genetic loss in the lethal pathogen Yersinia pestis has remained unresolved. Y. pestis and Salmonella enterica express beta-barrel

A novel fimbrial type in Escherichia coli was identified and characterized. The expression of the fimbria was associated with the O18acK1H7 clonal group of E. coli , which cause newborn meningitis and septicemia when grown at low temperature; hence,
