Maximum-parsimony tree of 98 human isolates and 5 linked food and veterinary isolates of Salmonella enterica serovar Typhimurium with mainly ST19 based on core-genome SNP analysis with an internal de novo assembled ST19 genome as the reference genome in an outbreak investigation of Salmonella Typhimurium and its monophasic variants, Denmark. Branch lengths correspond to number of SNPs. Isolates belonging to outbreaks B and C are as previously defined by MLVA. Isolate inside the dotted circles ar

Figure 3. Maximum-parsimony tree of 98 human isolates and 5 linked food and veterinary isolates of Salmonella enterica serovar Typhimurium with mainly ST19 based on core-genome SNP analysis with an internal de novo assembled ST19 genome as the reference genome in an outbreak investigation of Salmonella Typhimurium and its monophasic variants, Denmark. Branch lengths correspond to number of SNPs. Isolates belonging to outbreaks B and C are as previously defined by MLVA. Isolates inside the dotted circles are outbreak isolates as defined by the SNP analysis. MLVA, multilocus variable-number of tandem-repeat analysis; SNP, single-nucleotide polymorphism; ST, sequence type.
