Extended-Spectrum Beta-Lactamase (ESBL)-Producing Escherichia coli versus Klebsiella pneumoniae: Does type of germ really matter?

Abstract

The presence of cluster I in both ICUs, identical to the endemic cluster described by Saalffeld et al, 4 demonstrates the importance of interhospital dissemination. Although the environment was not the main cause of dissemination, we believe that the contamination of the hands of healthcare professionals may have contributed to the dissemination of A. baumannii isolates, and the failure to verify this dissemination route was a limiting factor in our study. Our study showed that after the ICU was re-established in a new building (ie, a new ICU), the dissemination of endemic clone-producing OXA-23 was maintained even though the new ICU environment was not contaminated. This occurrence demonstrates that additional measures are required to control the dissemination of this important hospital pathogen. Financial support.

Risk Factors for Recurrence of Community-Onset Urinary Tract Infections Caused by Extended-Spectrum Cephalosporin-Resistant Enterobacterales

“…The existing literature on differences in outcomes of ESBL K pneumoniae versus ESBL E coli infections is inconclusive. Some studies have reported increased 30-day mortality among ESBL K pneumoniae compared to ESBL E coli infections [ 18 , 19 ], while others have shown no difference in outcomes [ 20 ]. Future studies are needed to elucidate the role of organism type in outcomes of ESCrE UTIs.…”
