Figure 1

Phylogenetic dendrogram of Salmonella enterica serovar Heidelberg containing extended-spectrum β-lactamase genes, Canada. The maximum-likelihood dendrogram was created by using the single-nucleotide variant (SNV) phylogenomics (SNVPhyl) pipeline (https://snvphyl.readthedocs.io/en/latest) based on SNVs in the core genome. The reference genome is Salmonella Heidelberg strain 12-4374 (GenBank accession no. CP012924.1). The tree is based on a core genome that represents 94% of the reference genome. Numbers along branches indicate branch support values. Salmonella Heidelberg containing extended-spectrum β-lactamases were from animals (green, n = 5), food (blue, n = 1), and humans (orange, n = 16). Extended-spectrum β-lactamase genes are indicated to the right of the 3 largest clusters. The dataset comprises 394 SNVs, and SH-like branch support values are displayed.
