Salmonella Paratyphi B variant L(+) tartrate(+) and Salmonella Weltevreden whole-genome sequencing analysis. Phylogenetic analysis of Salmonella Paratyphi B variant L(+) tartrate(+) (a) and Salmonella Weltevreden genomes (b). Genomes in bold italics are from tuna samples, remaining are clinical samples. The relevant SNP differences and noted next to brackets on the right of outbreak clades; differences between clades are noted to the left. (a) Sixteen Salmonella Paratyphi B (dT+) genomes (15 clinical and one tuna) comprising both outbreak-associated PFGE patterns are closely related genetically (0–4 nqSNPs). Genome 2015AM-0987 is a non-outbreak-associated outgroup. (b) Sub-clade 1 includes three tuna genomes from samples collected in Minnesota and one clinical genome from an Arizona case-patient; all are closely related (0 hqSNPs). Sub-clade 2 includes three clinical genomes from Wisconsin case-patients; all are closely related (0 hqSNPs). The two remaining genomes not included in either sub-clade are from tuna samples collected in Arizona and Minnesota; neither is closely related to other genomes in the analysis (70–450 hqSNPs, median 314 hqSNPs).
