1051. Increased Mortality in Bacteremia by Enterobacter Species With Discordant Imipenem and Ertapenem Susceptibilities

Carbapenem-resistant Enterobacteriaceae (CRE) that are resistant only to one carbapenem have been reported, but the frequency of discordance between ertapenem and imipenem/meropenem is not known for Enterobacter species. We investigated the occurrence of discordant carbapenem susceptibilities in Enterobacter species bacteremia and the potential association with increased mortality
