Tu1113 A BENCHTOP EVALUATION OF VARIOUS SUSPECTED BIOFILM RESERVOIRS WITHIN A DUODENOSCOPE

Multidrug resistant organisms (MDRO) / carbapenem resistant enterobacteriaceae (CRE) have emerged as serious public health problems, particularly among immune compromised patients. It is now known that duodenoscopes may transmit MDRO due to biofilm buildup, which may explain prior CRE outbreaks with culture-negative duodenoscopes. However, the precise location of biofilm buildup has been the subject of speculation. Thus, we aimed to investigate various suspected biofilm reservoir locations & scenarios among key, hard-to-reach components of a duodenoscope.
