a Maximum clade credibility trees and phylogeographical inference. The inferred median MRCA age of each lineage is shown with 95% HPD. MRCA, most recent common ancestor; HPD, highest posterior density. Terminal branches are color coded by the isolates’ continent of origin. Internal branches are colored to indicate the predicted geographical origin with the highest posterior probability value inferred using maximum-likelihood ancestral trait reconstruction. The scale bars indicate 10 SNPs. b, c Bayesian skyline plots showing the historical changes of the effective population size of poultry Salmonella Enteritidis populations in the Global and the Atlantic lineages. Blue lines represent the medians of estimated effective population sizes. Blue shadings indicate the upper and lower bounds of the 95% HPD intervals.
