Single nucleotide polymorphisms (SNPs) used for minimum core sequencing (MCG).

MCG groups as defined by Zheng et al. [42] including 5 novel MCG groups identified in the present study. Red highlights discriminative SNPs for each SNP profile.

^aReference genome: strain GZ1 (GenBank accession number: CP000837).

^bEpidemic (E) strains (ST7 strains) identified by Zheng et al. [42].

^cUngroupable.

The following isolates resulted in novel MCG groups with a new SNP profile.

^dMB1158 (cps type 5), MB1497, SS2097 (cps type 9), PP106 (cps type 19), MB1185 (cps type 21), SS921 (nontypeable).

^eMB1629 (cps type 12).

^fHuman pathogen strain (cps type 14).

^gMB 1297 (cps type 31).

^hSS 3919 (cps type 31).
