A novel polytetrafluoroethylene-channel model, which simulates low levels of culturable bacteria in build-up biofilm after repeated endoscope reprocessing

Clinical studies have shown variable culture results from flexible endoscope channels possibly due to low levels of bacteria that are difficult to extract. The aim of this study was to develop a simulated-use buildup biofilm (BBF) model that mimics low levels of viable bacteria after repeated rounds of aldehyde fixation and accumulation.
