Comparison of Salmonella enterica phylogenetic trees based on core genome single nucleotide polymorphisms using ParSNP [27] and the alignment-free whole genome comparison with feature frequency profiling of purine-pyrimidine words (FFPry) with a word length (L) of 18 [28], using the 200 Salmonella genomes included here, visualised using the serovars (colored bar) and a tanglegram in the middle to indicate position of individual genomes in both phylogenetic trees. The left panel represents the phylogenetic tree based on core genome SNPs, while the right panel shows the phylogenetic tree obtained FFPry. Note that although the order of serotypes differs, isolates cluster generally according to serotype in both analysis methods, with the overall topology being similar. Clusters containing major serovars are indicated by numbers: 1. Johannesburg; 2. Muenster; 3. Schwarzengrund; 4. Worthington; 5. Altona; 6. Mbandaka; 7. Senftenberg; 8. Rissen; 9. Derby; 10. Typimurium and 4,[5],12:i:-
