MDRO colonization patterns for 234 NH residents. The prevalence of most commonly observed multidrug-resistant organisms (MDROs) in the groin or perirectum of 234 nursing home residents who had a urinary catheter in place for >72 h is shown. Each column in the heatmap represents a catheterized resident, and each colored cell indicates colonization by the corresponding MDRO during their stay. The facility each resident resided in is color-coded on the top of the heatmap, with legend provided on the right (A–L). The total number of different species detected in each resident over time is summarized in the black barplot above.
