Introduction: Burkholderia cepacia complex (Bcc) has emerged as a serious nosocomial pathogen worldwide especially in patients with indwelling catheters and cystic fibrosis. Bcc is a common contaminant of pharmaceutical products. We describe an outbreak of Bcc bacteraemia amongst children admitted in Paediatric Intensive Care Unit (PICU) and paediatric ward at a tertiary care hospital, Mumbai, in Western India. Materials and Methods: Blood culture samples from paediatric patients yielded growth of non-fermenting, oxidase positive, motile, Gram negative bacilli (NFGNB) (76/909) over a period of 8 months. Based on conventional biochemical tests and antimicrobial susceptibility testing, these isolates were provisionally identified as Bcc. The increased, repeated and continued isolation of Bcc alerted the possibility of an outbreak confined to PICU and paediatric ward. Active surveillance was undertaken to trace the source and contain the outbreak. Isolates were subjected to recA polymerase chain reaction (PCR) and Expanded multilocus sequence typing (EMLST). Results: Surveillance revealed the presence of Bcc on the upper surface of rubber stopper of sealed multidose amikacin vials. Isolates from blood culture and rubber stoppers were confirmed as Bcc by recA PCR. EMLST revealed that these isolates shared an identical novel sequence type 824 proving clonality. Timely interventions instituted led to control of the outbreak. Conclusion: This study highlights the importance of identification and molecular characterization of Bcc to establish its role in infection and outbreak.
