* The accession numbers are provided for the strains, including three environmental E. coli O45:H16 strains and one clinical E. coli O45:H2 strain (SJ7), which were sequenced in this study with the given accession numbers. Additionally, “reference” indicates the chromosome and plasmid of two clinical strains (FWSEC0003 and 2011C-4251) obtained from the National Center for Biotechnology Information (NCBI) with the accession numbers indicated in Table S1. α The strains contained two different plasmids.
