Heatmap showing the presence of β-lactamase genes and virulence factors and multidrug-resistant status stratified by A infection-causing isolates, B isolates associated with possible infection, C colonization isolates, and D environmental isolates. Infection-causing isolates include bloodstream infection-causing isolates (n = 24) and one isolate from pus. Possible infection-causing isolates are isolates from ET tube culture (n = 10) and UVC tip culture (n = 3). Colonizing isolates include those obtained from cultures of armpit swab (n = 1), rectal swabs (n = 2), and umbilical swabs (n = 9). Environmental isolates were obtained from the basin (n = 5) and patient’s bed surface (n = 2) swab cultures
