FIG 4.

Presence of acquired resistance determinants among bloodstream isolates. A binary heatmap is shown based on the presence or absence of specific acquired resistance genes present among all infectious isolates. The x axis is organized alphabetically by species, and the y axis is organized according to the antibiotic resistance conferred by each gene. The heatmap is colored from pale red, indicating a gene is not present, to bright red, indicating that a gene is present in that isolate. Species are abbreviated as follows: Escherichia coli, EC; Enterococcus faecium, Efm; Enterococcus faecalis, Efa; Pseudomonas aeruginosa, PA; Klebsiella pneumoniae, KP; Staphylococcus aureus, SA; Staphylococcus epidermidis, SE; and viridans group streptococci, VGS.
