A Prospective, Randomized Comparison of Duodenoscope Reprocessing Surveillance Methods

Figure 1

CDC interim duodenoscope surveillance method. (a) The channel cleaning brush is used to sample the distal end of the duodenoscope and placed in a specimen cup containing PBS-T. (b) The syringe containing water is used to flush the instrument channel via the instrument port and collected in a specimen cup. (c) A total of 45 mL from each specimen cup is concentrated via centrifugation. (d) A total of 1 mL unconcentrated specimen is inoculated in 5 mL TSB. (e) A total of 1 mL concentrated specimen is inoculated in 5 mL of TSB. All cultures are subsequently incubated at 37°C for 48 hours.
