Genetic analysis of virulence plasmid from a serogroup 9 Yersinia enterocolitica strain: role of outer membrane protein P1 in resistance to human serum and autoagglutination.


Enteropathogenic strains of Yersinia enterocolitica harbor a virulence plasmid (70 kilobases) which specifies, at 37 degrees C, a calcium requirement for growth, autoagglutinability, resistance to the bactericidal activity of human serum, and the expression of some outer membrane proteins (OMPs). To map the genes encoding these properties, the virulence… (More)
