COLOREX Listeria is suitable for isolation and easy chromogenic differentiation of L. monocytogenes from clinical samples, e.g. blood culture, rectal/vaginal swabs or CSF.
Please note: This product is a custom pour, and not stocked regularly. Please call for more information.
COLOREX™ Listeria and COLOREX ID Listeria, traditionally used in tandem, isolate and chromogenically differentiate colonies confirming the presence of Listeria monocytogenes. When used together, COLOREX Listeria provides initial differentiation and presumptive identification, while COLOREX ID Listeria provides confirmation of suspect L. monocytogenes colonies re-plated from COLOREX Listeria. Together they make preliminary detection and confirmation easy by producing distinct chromogenic differences with typical identifying characteristics, both macro and microscopically, within as little as 18-24 hours. Both devices inhibit the growth of mold, fungi, and other bacteria including E. coli and E. faecalis.
