Specificity of the complement resistance and cell association phenotypes encoded by the outer membrane protein genes rck from Salmonella typhimurium and ail from Yersinia enterocolitica

Abstract

Virulence-associated phenotypes of an outer membrane protein gene family of members of the family Enterobacteriaceae were compared by means of pBR322 constructs transformed into Escherichia coli HB101. rck (Salmonella typhimurium) and ail (Yersinia enterocolitica) promote serum resistance and eukaryotic cell invasion, properties not shared by other members of the gene family, pagC, ompX, and lom.
