Development of rRNA-based PCR assays for identification of Burkholderia cepacia complex isolates recovered from cystic fibrosis patients.

ABSTRACT: PCR assays targeting rRNA genes were developed to identify species (genomovars) within the Burkholderia cepacia complex. Each assay was tested with 177 bacterial isolates that also underwent taxonomic analysis by whole-cell protein profile. These isolates were from clinical and environmental sources and included 107 B. cepacia complex strains, 23 Burkholderia gladioli strains, 20 Ralstonia pickettii strains, 10 Pseudomonas aeruginosa strains, 8 Stenotrophomonas maltophilia strains, and 9 isolates belonging to nine other species. The sensitivity and specificity of the 16S rRNA-based assay for Burkholderia multivorans (genomovar II) were 100 and 99%, respectively; for Burkholderia vietnamiensis (genomovar V), sensitivity and specificity were 87 and 92%, respectively. An assay based on 16S an
