Fig 1.
Phylogenetic tree of Salmonella Typhimurium pairs.
Maximum likelihood phylogenetic tree of Salmonella Typhimurium paired isolates, mapped on reference strain Salmonella Typhimurium D23580 (Accession Number = NC_016854) and rooted on Salmonella Typhi 10040_15 (Accession Number = ERS1574281). The tree scale represents the number of SNPs, which are also annotated on the branches. The isolate names have a prefix representing the pair number followed by the study number of each isolate (S2 Table) and a suffix between brackets indicating the MVLA type. Isolates highlighted in orange are pairs showing low genetic similarity and were considered genetically different (orange highlight, pairs N° 12 and 31); isolates highlighted in yellow are pairs that despite not showing highest genetic relatedness were considered genetically similar based on the MLVA type, the SNP difference and the bootstrap values of the branch nodes (yellow highlight, pairs N° 43 and 44). The bar on the right indicates the specimen of isolation (blood isolate (red) versus stool isolate (brown)).
