Antimicrobial Susceptibility of Enterobacteriaceae and Pseudomonas aeruginosa Isolates from United States Medical Centers Stratified by Infection Type: Results from the International Network for Optimal Resistance Monitoring (INFORM) Surveillance Program, 2015 –2016

A total of 18,656 Enterobacteriaceae and 4,175 Pseudomonas aeruginosa were consecutively collected from 85 US hospitals and tested for susceptibility by broth microdilution methods in a central monitoring laboratory (JMI Laboratories). The antimicrobial susceptibility and frequency of key resistance phenotypes were assessed and stratified by infection type as follows: bloodstream (BSI; 3,434 isolates; 15.0%), pneumonia (6,439; 28.2%), skin and skin structure (SSSI; 4,134; 18.1%), intra-abdominal (IAI; 951; 4.2%), and urinary tract (UTI; 7,873; 34.5%).
