*Nosocomial isolates encompass ventilator-associated pneumonia and hospital-acquired pneumonia isolates. CC87, clonal complex 87 (sequence type complex [STc] 155) (19); CGA, clonal group A (STc69) (21); ST131, sequence type 131
The correspondence with the Achtman MLST schema is as follows: subgroup I, STc131; subgroup II, STc73; subgroup III, STc127; subgroup IV, STc141; subgroup V, STc144; subgroup VI ,STc12; subgroup VII, STc14; subgroup IX, STc95. No isolate belonged to subgroup VIII (STc452), X (STc372), or E phylogroup (22).
†Proportions of subgroups are reported as fractions of the respective phylogroups.
