Colistin Resistance in Carbapenem-Resistant <i>Klebsiella pneumoniae:</i> Laboratory Detection and Impact on Mortality

Abstract

In this cohort, 13% of patients with CRKp presented with ColR CRKp. The apparent polyclonal nature of the isolates suggests de novo emergence of ColR in this cohort as the primary factor driving ColR. Importantly, mortality was increased in patients with ColR isolates.
