Appendix 1—table 3. Summary statistics of the core genome alignments of the different bacterial species.

For each species, the number of strains, the median genome size, the size of the core genome alignment, and the total number of informative SNPs (that is SNPs that occur in at least two strains) are listed.

Species	Strains	Genome size	Core size	Inf. SNPs
Escherichia coli	92	4,929,299	2,756,541 (56%)	247,822
Bacillus subtilis	75	4,155,843	2,341,553 (56%)	182,535
Helicobacter pylori	83	1,655,288	850,827 (51%)	114,993
Mycobacterium tuberculosis	40	4,465,985	4,150,139 (93%)	3502
Salmonella enterica	155	4,810,980	2,846,634 (59%)	192,117
Staphylococcus aureus	95	2,881,899	2,002,833 (69%)	73,756
