Abstract

Definitive identification of Brucella species remains a challenge due to the high degree of genetic homology shared within the genus. We report the development of a molecular technique which utilizes real-time PCR followed by high-resolution melt (HRM) curve analysis to reliably type members of this genus. Using a panel of seven primer sets, we tested 153 Brucella spp. isolates with >99% accuracy compared to traditional techniques. This assay provides a useful diagnostic tool that can rapidly type Brucella isolates and has the potential to detect novel species. This approach may also prove helpful for clinical, epidemiological and veterinary investigations.
