BackgroundWe report an outbreak of Burkholderia cenocepacia bacteremia and infection in 11 patients predominately in intensive care units caused by contaminated ultrasound gel used in central line insertion and sterile procedures within 4 hospitals across Australia.MethodsBurkholderia cenocepacia was first identified in the blood culture of a patient from the intensive care unit at the Gold Coast University Hospital on March 26, 2017, with 3 subsequent cases identified by April 7, 2017. The outbreak response team commenced investigative measures.ResultsThe outbreak investigation identified the point source as contaminated gel packaged in sachets for use within the sterile ultrasound probe cover. In total, 11 patient isolates of B cenocepacia with the same multilocus sequence type were identified within 4 hospitals across Australia. This typing was the same as identified in the contaminated gel isolate with single nucleotide polymorphism-based typing, demonstrating that all linked isolates clustered together.ConclusionArresting the national point-source outbreak within multiple jurisdictions was critically reliant on a rapid, integrated, and coordinated response and the use of informal professional networks to first identify it. All institutions where the product is used should look back at Burkholderia sp blood culture isolates for speciation to ensure this outbreak is no larger than currently recognized given likely global distribution.
