In January 2014 a possible outbreak of Burkholderia cepacia bacteremia occurred in a hemodialysis center situated in La Linea de la Concepción (Cadiz). An investigation was begun to confirm the outbreak, identify the source, and implement control measures.A descriptive analysis was performed to describe the characteristics of the patients affected with Burkholderia cepacia bacteremia from November 2013 to February 2014. Environmental samples were taken. A molecular typing study was performed using pulsed field gel electrophoresis (SpeI PFGE) and MLST analysis in order to determine the genetic similarity between the isolates.The bacterium was isolated from blood cultures of 7 patients during the study period. Three of the samples (2 of which were also cases) were endoluminal fluid from catheter locks, and 4 chlorhexidine bottle samples. The patients were coincident in 2 of the 6 work shifts. The mean age of the cases was 67 years of whom 57% were women. Human samples and an environmental sample was analyzed and found to be genetically identical (ST653 clone).The analysis confirmed the outbreak of Burkholderia cepacia, with 7 cases among the patients of the hemodialysis center. The outbreak was due to the same strain, probably a common source and secondary transmission from person to person.
