Cluster of Pseudoinfections with Burkholderia cepacia Associated with a Contaminated Washer-Disinfector in a Bronchoscopy Unit

In December 2008, bronchoalveolar lavage fluid samples obtained from 3 patients were positive for Burkholderia cepacia complex on culture. Samples obtained from bronchoscopes and rinse-water samples obtained from the washer-disinfector were found to be positive for B. cepacia complex. The cause of this pseudo-outbreak was that the washer-disinfector was installed without the required antibacterial filter.
