Through its new “Microbial Identification Program,” the Silliker Food Science Center can provide companies with accurate and reliable source tracking services utilizing two state-of-the-art technologies: gene sequencing and molecular subtyping by rep-PCR. For bacterial isolates, including Salmonella, Escherichia, and Listeria monocytogenes, rep-PCR is a reliable tool for strain differentiation and comparison. This DNA-based method uses repetitive-element PCR to “fingerprint” genetic sequences of samples.
