Performance of Polymyxin B Etest® in a setting of high prevalence of KPC-producing Klebsiella pneumoniae

ConclusionsThe considerable number of resistant isolates in this study allowed an accurate estimation of VME rates and, consequently, a more comprehensive assessment in susceptibility testing for polymyxins. Etest® did not meet fully acceptance criteria for the FDA requirements. Our data do not support the use of this commercial method for determining PMB MICs in carbapenem-resistant Enterobacterales populations.
