Primary Objective
To determine AMR rates in key gram-negative pathogens from global sites


Protocol SummaryStudy organisms were clinical isolates previously collected and frozen at -70°C. Isolates were from documented infections (clinically relevant causative agent), with only one isolate per species per patient allowed. Isolates were from community- and hospital-associated infection sources, distributed globally with a focus on the United States and Europe. Patient locations included: General Medicine; Medical ICU; Surgery General; Surgery ICU; Emergency Room; Pediatric ICU; General ICU; and Pediatric General. Isolates were sourced from: respiratory tract infections, urinary tract infections, bloodstream infections, intraabdominal infections, and skin/soft tissue infections. Organisms included Enterobacterales, Pseudomonas aeruginosa, Stenotrophomonas maltophilia and methicillin-susceptible Staphylococcus aureus. The identities of all isolates were confirmed using MALDI-TOF mass spectrometry. Broth microdilution MICs were determined using the ISO 20776-1:2019/CLSI M07 11th Ed. reference method. Quality control (QC) testing was performed each day of testing (CLSI M100).

Inclusions: human infection (clinically relevant causative agent), one isolate per infection episode; Exclusions: screening/carriage isolates, multiple isolates per infection episode.
Isolates collection methodClinically relevant causative agent only; one isolate per infection episode.
