  1. *Results are averaged from 118 chromosomes in 117 different strains [see Additional file 6] except for the "Literature" GIs, which were averaged over 5 strains; Escherichia coli O157:H7, E. coli O157:H7 EDL933, Salmonella enterica Typhi str. CT18, S. enterica typhimurium LT2, and Streptococcus pyogenes MGAS315 [21–25].
