Strains designated with the ‘CS’ prefix were derived from Escherichia coli K-12, which lacks the O-antigen (Liu & Reeves, 1994). Strains designated with the prefix ‘AG’ was derived from E. coli 2443, which expresses the O8-antigen (Rick et al., 1994). AG names followed by an asterisk (*) designate strains from which the O8-antigen genetic locus was deleted and replaced by mutated genes from E. coli K12.
