![Summary of posterior estimates of all 10 subsets of sequences of Salmonella enterica subspecies enterica 4,[5],12:i:- sequence type (ST) 34 collected from multiple sources in the United States and Europe during 2008–2017. A) Inferred time (year) of the most recent common ancestor of the emerging Salmonella 4,[5],12:i:- ST34 clade. B) Estimated mutation rate (uncorrelated log-normally distributed mean parameter). C–F) Number of unobserved transitions from Europe to the United States (C) and United States to Europe (E) along each branch (Markov jumps) and total phylogenetic tree length spent (Markov rewards) in Europe (D) and the United States (F). Violin plots illustrate the posterior distribution and probability density of each subset. Dashed red vertical lines indicate average posterior value; red shaded areas indicate average 95% highest posterior density credible interval of all subsets.](/eid/images/20-0336-F2.jpg)
