Development of a real-time fluorescence resonance energy transfer PCR to detect arcobacter species.

ABSTRACT: A real-time PCR targeting the gyrase A subunit gene outside the quinolone resistance-determining region has been developed to detect Arcobacter species. The species identification was done by probe hybridization and melting curve analysis, using fluorescence resonance energy transfer technology. Discrimination between Arcobacter species was straightforward, as the corresponding melting points showed significant differences with the characteristic melting temperatures of 63.5 degrees C, 58.4 degrees C, 60.6 degrees C, and 51.8 degrees C for the Arcobacter butzleri, Arcobacter cryaerophilus, Arcobacter cibarius, and Arcobacter nitrofigilis type strains, respectively. The specificity of this assay was confirmed with pure cultures of 106 Arcobacter isolates from human clinical and veterinary s
