Thermo Scientific™ Oxoid™ Brilliance™ Listeria Agar (ISO) Bottle

Enumerate and presumptively identify Listeria species and L. monocytogenes from food and environmental samples with the Thermo Scientific™ Oxoid™ Brilliance™ Listeria Agar (ISO) prepared bottles. The medium identifies Listeria species based on their utilization of X-glucoside, giving rise to blue-green colonies. Listeria monocytogenes are further differentiated by their ability to highly produce lecithinase, producing an opaque, white halo around the colony. Pour-plating enables enumeration of low contamination level samples with only one Brilliance Listeria agar plate. Pour-plating has shown equivalence to the ISO 11290-2 reference method with an ISO 16140-2:2016 validation study by AFNOR.
