title: Discrimination of Burkholderia multivorans and Burkholderia vietnamiensis from Burkholderia cepacia genomovars I, III, and IV by PCR.
abstract: We present a PCR procedure for identification of Burkholderia cepacia, Burkholderia multivorans, and Burkholderia vietnamiensis. 16S and 23S ribosomal DNAs (rDNAs) of B. multivorans and B. vietnamiensis were sequenced and aligned with published sequences for definition of species-specific 18-mer oligonucleotide primers. Specific antisense 16S rDNA primers (for B. cepacia, 5'-AGC ACT CCC RCC TCT CAG-3'; for B. multivorans, 5'-AGC ACT CCC GAA TCT CTT-3') and 23S rDNA primers (for B. vietnamiensis, 5'-TCC TAC CAT GCG TGC AA-3') were paired with a general sense primer of 16S rDNAs (5'-AGR GTT YGA TYM TGG CTC AG-3') or with a sense primer of 23S rDNA (5'-CCT TTG GGT CAT CCT GGA-3'). PCR with these primers under optimized conditions is appropriate to specifically and rapidly identify B. multivorans, B. vietnamiensis, and B. cepacia (genomovars I, III, and IV are not discriminated). In comparison with the polyphasic taxonomic analyses presently necessary for species and genomovar identification within the B. cepacia complex, our procedure is more rapid and easier to perform and may contribute to clarifying the clinical significance of individual members of the complex in cystic fibrosis.
