BAX® System PCR Assay for Listeria monocytogenes

The BAX® System PCR assay for Listeria monocytogenes can help companies monitor their environment and products for contamination with L. mono. With traditional culture methods, technicians may have trouble distinguishing Listeria monocytogenes from closely related organisms, and plating can take four days or more to get results. With the genetic-based BAX® System, however, accurate and reliable results are available within four hours after enrichment.
