    Abstract: Embodiments of the disclosure relate to isolated nucleic acid sequences, methods of use thereof, and workflows for detection of several Listeria species in a sample, particularly in a food or environmental sample. Embodiments of the disclosure may also be used to detect one or more species or strains of Listeria from each other, for example L. grayi may be detected independently of other Listeria spp. Some embodiments also describe a duplexed assay that can detect L. monocytogenes, L. innocua, L. welshimeri, L. seelgeri, L. marthii (formerly incertae-sedis), L. ivanovii, and L. grayi. Kits for detection of Listeria are also described. In some embodiments, methods and kits of the disclosure may comprise a TAQMAN® assay. In some embodiments, 0.2-2 cfu of Listeria spp. are detected using the compositions, methods and kits after a 24-28 hour enrichment period.
