National Surveillance of Antimicrobial Susceptibility of Bacteremic Gram-Negative Bacteria with Emphasis on Community-Acquired Resistant Isolates: Report from the 2019 Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART)

Abstract

A multicenter collection of bacteremic isolates of Escherichia coli ( n = 423), Klebsiella pneumoniae ( n = 372), Pseudomonas aeruginosa ( n = 300), and Acinetobacter baumannii complex ( n = 199) was analyzed for susceptibility. Xpert Carba-R assay and sequencing for mcr genes were performed for carbapenem- or colistin-resistant isolates. Nineteen (67.
