Burkholderia (previously Pseudomonas) isa Gram negative bacilli commonly found in soil and moist environments [1]. Small hospital outbreaks due to a single contaminated source suchas a disinfectant, intravenous solutions, nebulizer solutions, mouthwash and medical devices including respiratory-therapy equipment [1]. In our hospital, we had 3 reported cases of hospital acquired bloodstream infections caused by Burkholderia species from the pediatric ward. An outbreak investigation was conducted by the Hospital Infection Controlcommittee. The source was identified as distilled water used for nebulization in the pediatric ward.
