Easy detection of Listeria monocytogenes
in 24hr
Listeria readings and differentiation are easy thanks to chromogenic principle: blue colonies are Listeria monocytogenes; blue colonies with a yellow halo are ivanovii; white colonies are other spp
Bio-Rad has developed a new version of RapidL mono chromogenic medium, to provide laboratories with a quick response within 24hr after enrichment for the detection of Listeria monocytogenes, in food and environmental samples Moreover, the new RapidL mono provides simultaneous responses for Listeria monocytogenes and for Listeria spp, giving laboratories a cost-saving solution

Listeria agar differentiates quickly
Chromogenic medium will clearly differentiate L monocytogenes from L ivanovii and other listeria species by a simple colour change reaction within 24 hours
Listeria readings and differentiation are very easy thanks to RapidL mono's unique chromogenic principle: blue colonies are Listeria monocytogenes; blue colonies with a yellow halo are Listeria ivanovii; white colonies with or without yellow halo are other Listeria spp.
The RapidL mono method requires a single enrichment step in Fraser half for 24hr, then 0.1ml of Fraser half is removed, spread and isolated on RapidL mono agar before being incubated.
RapidL mono agar provides rapid, specific identification of Listeria monocytogenes in 24 hr and other species of Listeria in 24-48 hr after enrichment.
