Ochrobactrum anthropi pseudobacteraemias

About 95 blood isolates of Ochrobactrum anthropi have been referred for identification and/or typing over the past two years, originating from 30 hospitals in England and Wales.
Ochrobactrum anthropi is an oxidase-positive, motile, non-lactose fermenting Gram-negative bacillus, formerly known as Achromobacter sp.
It is normally found in the natural environment, sometimes acting as an opportunist pathogen in humans. About 40 of the isolates from nine of the referring hospitals were indistinguishable on pulsed-field gel electrophoresis (PFGE). No other PFGE profile was seen in more than one hospital, although there were 20 different distinguishable patterns for the other isolates of O. anthropi. Most, if not all, of the indistinguishable isolates were of doubtful clinical significance and appear to be pseudobacteraemias, often occurring in patients who were otherwise very ill.
This can clearly have an impact on the management of these patients. More than one blood culture system has been involved.
The Communicable Disease Surveillance Centre (CDSC) and Central Public Health Laboratory (CPHL) have been asked to investigate these apparent pseudobacteraemia incidents in order to identify any potential source of contamination. It would be helpful if microbiologists could discuss any further testing for possible O. anthropi pseudobacteraemia isolates with Polly Kaufmann from the Laboratory of Hospital Infection, Central Public Health Laboratory, Colindale (tel 020 8200 4400 ext 4205 email PKaufmann@phls.org.uk).

In some instances these organisms have been mis-identified as Pseudomonas stutzeri or Stenotrophomonas maltophilia, and they have also sometimes been found in mixed culture with S. maltophilia.
