Development of a multiplex PCR assay for the detection and differentiation of Burkholderia pseudomallei, Burkholderia mallei, Burkholderia thailandensis, and Burkholderia cepacia complex.

In this study, a multiplex PCR assay based on the detection of an individual set of chromosomal beta-lactamase genes for single-step identification and differentiation of B. pseudomallei, B. mallei, B. thailandensis, and Bcc was developed. Two pairs of primers specific to a distinct class of B metallo-beta-lactamase genes and a pair of primers specific to the oxacillin-hydrolyzing class D beta-lactamase gene were demonstrated to successfully discriminate species within Bpc and from Bcc. The assay sensitivity was 9561 genomic equivalents (GE) for B. pseudomallei, 7827 GE for B. mallei, 8749 GE for B. thailandensis and 6023 GE for B. cepacia.
