Figure 2

Allelic diversity analysis of the “Portuguese” (PT) S. enterica serovar Rissen, using a wgMLST-based gene-by-gene approach. Minimum spanning tree enrolls a total of 3465 shared loci. Nodes are colored by (a) region of isolation, (b) year of isolation, (c) sample type, and (d) antibiotic resistance profile. The numbers in red on the connecting lines represent the allelic distance between isolates. MDR: multidrug resistant.
