A duplex PCR (D-PCR) amplifying portions of the Brachyspira hyodysenteriae NADH oxidase gene and the B. pilosicoli 16S rRNA gene was developed and then tested on DNA extracted from 178 porcine fecal samples. The feces also underwent anaerobic culture and species-specific PCRs. Fecal extraction-D-PCR detected seven additional samples containing B. hyodysenteriae and five more containing B. pilosicoli.
