SNP-based (maximum likelihood) phylogenic tree of the 27 S. Infantis genomes (regarding 853 polymorphic sites across core positions). Each branch is colored according to the production stage and sample type origins. Bottom heatmap represents the pairwise distances in number of SNPs between the 27 genomes (displayed in the heat scale); identical genomes show a distance of 0. The left dendrogram corresponds to complete-linkage hierarchical clustering. Colors of the heatmap’s left columns represents the production stage and sample type. The genome of Salmonella Infantis CVM-N17S1509 (GenBank: CP052817.1) was used as reference.
