AIM:To conduct a bacterial culture study for monitoring decontamination of automated endoscope reprocessors (AERs) after high-level disinfection (HLD).METHODS:From February 2006 to January 2011,authors conducted randomized consecutive sampling each month for 7 AERs.Authors collected a total of 420 swab cultures,including 300 cultures from 5 gastroscope AERs,and 120 cultures from 2 colonoscope AERs.Swab cultures were obtained from the residual water from the AERs after a full reprocessing cycle.Samples were cultured to test for aerobic bacteria,anaerobic bacteria,and mycobacterium tuberculosis.RESULTS:The positive culture rate of the AERs was 2.0％ (6/300) for gastroscope AERs and 0.8％ (1/120)for colonoscope AERs.All the positive cultures,including 6 from gastroscope and 1 from colonoscope AERs,showed monofloral colonization.Of the gastroscope AER samples,50％ (3/6) were colonized by aerobic bacterial and 50％ (3/6) by fungal contaminations.CONCLUSION:A full reprocessing cycle of an AER with HLD is adequate for disinfection of the machine.Swab culture is a useful method for monitoring AER decontamination after each reprocessing cycle.Fungal contamination of AERs after reprocessing should also be kept in mind.
