Abstract: The use of whole-genome phylogenetic analysis has revolutionized our understandingof the evolution and spread of many important bacterial pathogens due to the highresolution view it provides. However, the majority of such analyses do not consider thepotential role of accessory genes when inferring evolutionary trajectories. Moreover,the recently discovered importance of the switching of gene regulatory elementssuggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could provide a super-resolution view into the evolutionof a bacterial population. Here we demonstrate this principle by applying it to aworldwide multi-host sample of the important pathogenic E. coli lineage ST131. Ourapproach reveals the existence of multiple circulating subtypes of the major drugresistantclade of ST131 and provides the first ever population level evidence of coregenome substitutions in gene regulatory regions associated with the acquisition andmaintenance of different accessory genome elements.
