SNP-based phylogenetic tree of the 21 STEC strains isolated from cattle samples collected in Chile (this study). The heatmap was constructed based on Clermont phylogroup, multilocus sequence typing (MLST), serotype, and presence/absence of Shiga-toxin subtypes and virulence, LAA-associated genes, and resistance genes. * Strain B-16 belongs to the novel ST-1661, a single locus variant (SLV) of ST33 at the fumC allele. ST11238 is an SLV of ST657 at the recA allele. SNP matrix is quoted in Table S3.
