Maximum parsimony trees defining the two outbreaks. (a) ST6 outbreak cluster, all ST6 isolates from the years 2013–15 are included. (b) ST391 outbreak cluster. In addition to all ST391 isolates from 2013–15 it includes two strains, ‘Other unrelated’, which are two ST391 human isolates from These were used as an outgroup for rooting the tree. Colours denote the year of isolation and if the strains were of patient (Human) or food or food production environment (Food) origin. Square symbols denote isolates belonging to the outbreak strains (ST6 or ST391), circles denote isolates that are not part of the clusters and hence not of the outbreak strains.
