Abstract

Burkholderia cepacia complex (BCC) is characterized by a complex taxonomy constituted by seventeen closely related species of both biotechnological and clinical importance. Several molecular methods have been developed to accurately identify BCC species but simpler and effective strategies for BCC classification are still needed. A single nucleotide primer extension (SNuPE) assay using gyrB as a target gene was developed to identify bacteria belonging to the B. cepacia (BCC) complex. This technique allows the successful detection and distinction of single nucleotide polymorphisms (SNPs) and is effectively applied in routine medical diagnosis since it permits to analyze routinely many samples in a few times. Seven SNuPE primers were designed analyzing the conserved regions of the BCC gyrB sequences currently available in databases. The specificity of the assay was evaluated using reference strains of some BCC species. Data obtained enabled to discriminate bacteria belonging to the species B. multivorans, B. cenocepacia (including bacteria belonging to recA lineages III-A, III-C, and III-D), B. vietnamiensis, B. dolosa, B. ambifaria, B. anthina and B. pyrrocinia. Conversely, identification failed for B. cepacia, B. cenocepacia III-B and B. stabilis. This study demonstrates the efficacy of SNuPE technique for the identification of bacteria characterized by a complex taxonomical organization as BCC bacteria.
