Epidemiology and Mechanisms of Carbapenem Resistance in Recurrent Extended-Spectrum ¦Â-Lactamase- Producing Enterobacteriaceae Bacteremia %J Archive of "Open Forum Infectious Diseases". %D 2018 %R 10.1093/ofid/ofy210.892 %X Carbapenems are the treatment of choice for bacteremia caused by extended spectrum ¦Â-lactamase producing Enterobacteriaceae (ESBL-E). The emergence carbapenem resistance (CR) in ESBL-E isolates has been described; however, the rate of such resistance in clinical settings is unknown. We describe the frequency and mechanisms of CR in recurrent ESBL-E bacteremia at an NCI-designated cancer center %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6253348/
