Diagnostic testing for bioterrorism agents in food is essential for the safety and welfare of the general populace. Multiplex assays provide the means to test for multiple pathogen signatures with a single polymerase chain reaction (PCR) test. PCR, Luminex xMAP ® infrared fluorophore bead technology, and flow cytometry, multiplex diagnostic assays are incredibly specific and sensitive to highly conserved regions at various loci in a microbe’s genome. In order to increase the effectiveness of the PCR and the resulting fluorescent response of the beads, different PCR master mix commercial kits were compared to the standard AgPath RT-PCR mix. This study specifically looks at Brucella abortus template 86/8/59 with the goal of finding the smallest concentration at which Brucella abortus can be detected and distinguished from Brucella melitensis.
