A Prospective, Randomized Comparison of Duodenoscope Reprocessing Surveillance Methods

Figure 2

UWHC duodenoscope surveillance method. (a and b) The Dacron swab is used to sample the distal end of the duodenoscope and plated on BA. (c) The distal end of the duodenoscope is immersed and agitated in a specimen cup containing TSB. (d) The syringe containing saline is used to flush the instrument channel via the instrument port and collected in a specimen cup. (e) The collected saline flush is then streaked for isolation onto BA and TSA. All cultures are subsequently incubated at 37°C for 5 days.
