FIGURE 4

Results of non-metric multidimensional scaling (NMDS) performed using the presence and absence of (A) pan-genome elements (n = 4,102; identified using Roary), and (B) antimicrobial resistance (AMR) and stress response genes (n = 28; detected using AMRFinderPlus) among 128 bovine-associated Salmonella isolates, plotted in two dimensions. Points represent isolates, while shaded regions and convex hulls correspond to isolate (1) serotypes (ANAT, Anatum; CERO, Cerro; KENT, Kentucky; MELA, Meleagridis; NEWP, Newport; TCOP, Typhimurium Copenhagen; TYPH, Typhimurium), (2) farm, and (3) source (BOV, bovine; ENV, bovine farm environment). For all plots, a Jaccard distance metric was used. For AMR/stress response genes (B), gene names/scores are plotted in dark gray text.
