Unveiling the hidden threat of carbapenemase-producing Enterobacteriaceae in hospital water environments: A single-center study.

This retrospective study examined the presence of carbapenemase-producing Enterobacteriaceae in hospital water environments. Results showed that carbapenemase-producing Enterobacteriaceae was detected in 41.5% of the samples within 1 m of a water source (showers or sinks), with 20.6% of the positive samples associated with shower water sources.
