An outbreak of Burkholderia multivorans beyond cystic fibrosis patients

Strains of the Burkholderia cepacia complex (Bcc) are opportunistic pathogens capable of causing serious infection in cystic fibrosis patients. Recently we identified a suspected outbreak of infection with Bcc strains at the University Hospital Olomouc. Seventy-four Bcc strains were isolated from 52 patients, most of whom (N = 48) did not suffer from cystic fibrosis. Most frequently (N = 46) Burkholderia multivorans was isolated and 24 (52.2%) of these strains were clonal. Fifteen of these strains were isolated from intensive care patients, five of whom died from hospital-acquired pneumonia. B. multivorans can cause serious outbreaks of infection beyond cystic fibrosis sufferers.
