Increased Detection Of Carbapenemase-Producing Enterobacteriaceae On Post-Clean Sampling Of Burns Units Wet Surfaces

We report the increased detection of bla-IMP-4+ CPE in environmental samples from floor drains in Burns Unit shower rooms, when collected following cleaning as compared to pre-cleaning. We propose that disruption of biofilms during cleaning may account for the increased detection of multi-resistant organisms. The results highlight the role of the wet environment as an under-recognised potential source of CPE transmission. Environmental screening focusing on pre-cleaning samples alone will likely under-estimate environmental contamination.
