Abstract

The prevalence, epidemiology, and genomovar status ofBurkholderia cepacia complex strains recovered from Italian cystic fibrosis (CF) patients were investigated using genetic typing and species identification methods. Four CF treatment centers were examined: two in Sicily, one in central Italy, and one in northern Italy. B. cepacia complex bacteria were isolated from 59 out of 683 CF patients attending these centers (8.6%). For the two geographically related treatment centers in Sicily, there was a high incidence of infection caused by a single epidemic clone possessing the cblA gene and belonging toB. cepacia genomovar III, recA group III-A, closely related to the major North America-United Kingdom clone, ET12; instability of the cblA sequence was also demonstrated for clonal isolates. In summary, of all the strains ofB. cepacia encountered in the Italian CF population, the genomovar III, recA group III-A strains were the most prevalent and transmissible. However, patient-to-patient spread was also observed with several other genomovars, including strains of novel taxonomic status within the B. cepacia complex. A combination of genetic identification and molecular typing analysis is recommended to fully define specific risks posed by the genomovar status of strains within the B. cepacia complex.
