A Pseudo-Outbreak of <b><i>Pseudomonas putida</i></b> and <b><i>Stenotrophomonas maltophilia</i></b> in a Bronchoscopy Unit

Abstract

We described a pseudo-outbreak related to a contaminated bronchoscope because of inadequate installation of the AER for used new water lines and because the new tubes were connected to the AER. The antibacterial filters of the AER used tap water, and this may have contained low levels of microorganisms. No serious clinical complications derived from this pseudo-outbreak.
