OBJECTIVES: To investigate and describe an outbreak of Burkholderia cepacia in a neonatal intensive care unit (NICU) and a pediatric intensive care unit (PICU), and to report the interventions leading to the cessation of the outbreak. DESIGN: We conducted an epidemiologic investigation of an outbreak of B. cepacia colonization or infection in two clinical wards during a 35-month period (December 1998 to October 2001). SETTING: A 500-bed, university hospital-affiliated, tertiary-care pediatric institution in Paris, France, with a 22-bed PICU and 31-bed NICU. METHODS: Ribotyping was used to determine the genotypes of B. cepacia isolates. Procedures for the maintenance and disinfection of respiratory therapy devices were reviewed. RESULTS: Thirty-two children were colonized (n = 14) or infected (n = 18) by B. cepacia in 2 wards (28 in the PICU and 4 in the NICU). In the PICU, a single ribotype was found among the isolates obtained from all of the patients except 1, and from the 6 isolates obtained from respiratory therapy devices (ie, heated humidifier water). In the NICU, the isolates obtained from the patients harbored a single ribotype unrelated to that of the epidemic strain isolated in the PICU; no environmental source of infection was found. CONCLUSION: Two different outbreaks appeared to be associated with 2 ribotypes, 1 of which was linked to patient-to-patient transmission via respiratory therapy devices. Complete elimination of the outbreak was achieved only when disposable, sterilizable, or easy-to-disinfect materials were used in the PICU. The source of infection in the NICU was not found.
