*CGA, clonal group A (sequence type complex [STc] 69) (21); CC87, clonal complex 87 (STc155) (19); –, <10%; +, 10%–20%; ++, 20%–30%; +++ 30–50%; ++++, >50% of isolates. Correspondence with the Achtman multilocus sequence typing schema is subgroup I = STc131; subgroup II = STc73; subgroup III = STc127; subgroup IV = STc141; and subgroup IX = STc95 (22).
†Proportions of subgroups are calculated within each respective phylogroup.
