Re: Cupriavidis pauculus

We have had no evidence of this in our micro-testing of scopes or our water samples.

Thanks

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.
