*CC, clonal complex; ST, sequence type; freq, frequency of isolates with the ST; SLV, single locus variant; DLV, double locus variant; SAT, satellite.
†We identified 9 clonal complexes and 17 singletons (11, 286, 5119, 162, 1, 3759, 23, 1943, 22, 944, 3471, 3333, 1011, 785, 3334, 4178, and 4013), defined as strains that do not fit in any group in the collection. Some groups have an ST that is the ancestral strain for that group (shown in boldface). Unique STs are shown in italics.
