Qiao F, Wei L, Feng Y, et al. - Given that contamination of handwashing sink can occur with carbapenem-resistant Klebsiella (CRK), including carbapenem-resistant Klebsiella pneumoniae (CRKP) and carbapenem-resistant Klebsiella oxytoca (CRKO), researchers here examined if they are major sources of CRK infections. In this prospective multicenter study conducted in 16 intensive care units (ICUs) (9 general and 7 neonatal) at 11 hospitals, they sampled 158 sinks at these locations to screen CRK. Among these, 6 CRKP and 6 CRKO were recovered from 12 sinks in 7 ICUs, corresponding to a 7.6% CRK contamination rate. Findings do not suggest contaminated sinks to be the major source of CRK in these local settings. They indicate ST789 blaNDM-5-carrying CRKP to possibly represent an emerging lineage causing neonatal infections.
