Hi Everyone,
I have had a recent spate where a number of my endoscopy procedure centre
clients have reported culturing of “Pseudomonas species” or Gram negative
bacilli after the monthly water testing of the Automated Endoscope
Reprocessors.Upon further investigation, the organism has been identified as Cupriavidis
pauculus. This organism is often associated with ultra filtration systems
and although it has low pathogenicity it is a risk to immunocompromised
patients.Despite repeated water line disinfections, filter changes, disinfectant
dumps etc this bug keeps cropping up over and over again. We find that we
have cleared it in the next test after filter changes etc etc but then a
month later – we get a positive result again.Whilst in low numbers, it is causing some concern regarding potential risks
to patients. In all cases we are not growing the organism form the
endoscopes.I am wondering if anyone else has been experiencing the same issues?
If so – what did you do about it both in terms of managing the machines and
the risks to patients?If you have cultured this organism, did you manage to identify the cause of
the problem?Happy to chat offline.

19/02/2014 at 4:32 pm #70819Dear Terry,
I have seen this organism identified twice in water sampled from a showerhead, when screening for MRPA.
In one case repeated flushing, cleaning & disinfection did not help to clear the organism and as it was in a shower in a haematology unit we ended up changing the shower head and hose, no further problems to date.
I’ve not seen it in water tested from the Automated Endoscope Reprocessors.
As water is not generally screened for these types of organisms within a HCF if is impossible to know if this occurs commonly or not, it was the only time we have found it in our sampling and we have taken hundreds of samples over the past year.

Hi Terry,
I’d be looking for a design flaw in the Automated Endoscope Reprocessors
that is hindering contact of the cleaning and disinfecting agents with every
potentially contaminated surface particularly given that it sound like it is
in more that on processor. Is that correct?Cross sectional drawing of the Automated Endoscope Reprocessor components
might be useful in identifying sections of the reprocessor that are
hindering contact of the cleaning and disinfecting agents.See John Hopkins experience with design flaws in a bronchoscopes:

bronchoscopeshttp://www.ncbi.nlm.nih.gov/pubmed/12529462

Interesting question and interesting set of responses.I have sent it along to Bill Rutala to see his opinion. Will keep you posted on any reply.
Out of interest have you seen any illness among pts that could correlate with this org (I note the at risk group you mention)?

Hi Everyone,
Thanks for your responses. Cath, thanks for referring this on to Bill – I
look forward to hearing what he has to contribute.None of the patients have been affected by this organism. We are culturing
it in very low numbers [<100cfu] from the Automated Flexible Endoscope
Reprocessor [AER] only, however as it is being initially reported as a gram
negative bacilli or a pseudomonas species, alarm bells have rung and we have
asked for the organism to be identified so we can take appropriate action to
protect our patients.Unfortunately the GENCA (2010) guidelines do not have a flow chart to assist
in the response to positive cultures of an AER, so the approach we have
taken from a risk management perspective is to follow the recommendations
for a contaminated endoscope and have consulted the microbiologists from
the various pathology labs.My original thoughts were that it could be arising from the filters or
potentially be contaminating the fluid pathway of the AER, however the
affected machines are different models [same brand], different disinfectant
[for one] and the clients are not all using the same brands of filters. They
are however, located in a similar geographical area.My primary question is – given the organism has low pathogenicity, do we
really need to be concerned if the count is <100cfu?Thoughts anyone?
