Figure 2. Origins and serotypes of 51 Shiga toxin–producing Escherichia coli isolates from study of HUS in adults and Shiga toxin–producing Escherichia coli negative for locus of enterocyte effacement, France, 2025. Shown are the outbreak strain (HC5 326896, in purple) and other strains with the same core-genome multilocus sequence typing HC200 2073 group identified in EnteroBase and GenBank (Appendix Table 1). Only HC5 comprising >2 genomes are colored. Country of origin, year of isolation, source, disease, and O and H serotypes are indicated; O77 g denotes serogroup from the O77 group. Dash indicates the serotype is not available. AUS, Australia; BEL, Belgium; CAN, Canada; FRA, France; HUS, hemolytic uremic syndrome; SCT, Scotland; UK, United Kingdom; USA, United States.
