Fig. 1: Distribution of genetic distance for E. coli O157:H7 (nā=ā121) isolated from pigs, cattle, and pork production environment.

The distance was calculated from core SNP analysis (SNPs), cgMLST (allelic distance), wgMLST (allelic distance), and gene content analysis (Jaccard distance). Y-axis represents the number of combinations. There were a total number of 7260 combinations for the 121 genomes.
