Trends in the Incidence of Bacteremia with Carbapenem Non-susceptible Acinetobacter spp. in Patients from the US Veterans Health Administration, 2000–2015

Abstract

Conclusion. To our knowledge, these are the first systematic data showing bacteremia by Enterobacter spp. with discordant ertapenem and imipenem/meropenem susceptibilities is not infrequent; interestingly, ertapenem susceptible/imipenem non-susceptible was more common than ertapenem non-susceptible/imipenem susceptible isolates. Bacteremia by Enterobacter isolates with discordant carbapenem results were rapidly cleared and no difference in mortality was detected.Disclosures. All authors: No reported disclosures.
