TABLE 3.

Range of hqSNP, cgMLST, and wgMLST allele differences between strains for the outbreaks included in this study.

	Range of pairwise distances by typing method
Outbreak number assigned in study	SNP	cgMLST	wgMLST (chromosomal loci)	wgMLST (all loci)	Total number of isolates extending allele difference range by wgMLST (all loci)	Number of outbreak isolates with allele differences aligned to plasmid-associated loci* (isolate identifiers)

02	0–33	0–21	0–28	0–28
03	0–10	0–4	0–8	0–66	7	4 (PNUSAS054137, PNUSAS051669, PNUSAS038526, PNUSAS037576)

For wgMLST allele differences, ranges are shown for both the chromosomal loci and all loci. Two outbreaks with extended allele difference ranges by wgMLST (all loci) are highlighted in gray, and, within these outbreaks, the number of isolates aligned to plasmid-associated loci is shown. The background color shading indicates the two outbreaks with isolates aligned to plasmid-associated loci.
