Antigenic cross-reactions between fimbriae expressed by Salmonella enteritidis, S. dublin and an 18 kDa outer membrane associated protein expressed by Escherichia coli O126: H27

A commercial kit (SEFEX), designed to detect strains of Salmonella enteritidis, was used to demonstrate antigenic cross-reactions between the fimbriae of S. enteritidis and an 18 kDa outer membrane protein expressed by enteroaggregative strains of E. coli O126: H27.
