The relevance of sink proximity to toilets on the detection of Klebsiella pneumoniae carbapenemase inside sink drains

Am J Infect Control. 2019 Jan;47(1):98-100. doi: 10.1016/j.ajic.2018.06.021. Epub 2018 Aug 29.

Abstract

We report a higher prevalence of blaKPC in patient room sink drains located next to toilets (87.0%) when compared with sink drains located farther away from toilets (21.7%) using direct polymerase chain reaction assay. However, culture methods were only able to recover blaKPC-positive isolates from 16% of polymerase chain reaction-positive drains.

Keywords: Carbapenem-resistant organisms; Disinfection; Kpc; Pipes; Sink drains; Sinks.
