  1. Data shown represents one sequenced isolate per unique infection episode (n = 294). Cells show number of isolates of each species (column) that exhibit a given trait (row). Percentages in brackets indicate the frequency of the trait within the given species; except for the last row which shows the total number of infection episodes for each species, and the percentage this represents of the total infections. ESBL = extended spectrum beta-lactamase; MDR = resistance to ≥3 drug classes except ampicillin; Ybt = yersiniabactin, Iuc =  aerobactin.
