A multiplex PCR assay was developed for the simultaneous detection of the etiologic agents associated with porcine proliferative enteropathies (PPE), swine dysentery (SD)and porcine salmonellosis (PS)in a single reaction using DNA from swine intestinal samples. Single and multiplex PCR amplification of DNA from Lawsonia intracellularis, Salmonella typhimurium and Brachyspira hyodysenteriae with each primer set produced fragments of the predicted size without any nonspecific amplification,... -

Scrapie is diagnosed antemortem in sheep by detecting misfolded isoforms of prion protein (PrP) in lymphoid follicles of the rectal mucosa and nictitating membranes. Assay sensitivity is limited if (a) the biopsy is collected early during disease development, (b) an insufficient number of follicles is collected, or (c) peripheral accumulation of PrP is reduced or delayed. A blood test would be convenient for mass live animal scrapie testing. Currently approved techniques, however, have their own...
