Oxoid says it is able to offer food microbiologists one of the widest selections of products available for the rapid and convenient detection of listeria from food and environmental samples
Oxoid Novel Enrichment Broth - Listeria (product code CM1066 and SR0234) is described as a unique new selective enrichment broth that eliminates the need for sub-culturing from a pre-enrichment broth, providing a simpler procedure and allowing faster detection of listeria-positive samples.
Oxoid Chromogenic Listeria Agar (product code PO5165) is an innovative chromogenic medium that uses colour to improve the isolation, enumeration and presumptive identification of listeria species and allows the differentiation of pathogenic Listeria monocytogenes and Listeria ivanovii from other listeria species.
The Oxoid Listeria Rapid Test (FT0401) combines a specially optimised enrichment procedure and an innovative rapid end-point test to detect listeria spp within just 43 hours.
This highly sensitive and specific test has received Afnor, AOAC-RI, Emmas and DanVal approval.
Confirmation of listeria isolates can be performed quickly using the new Oxoid Listeria Diagnostic Reagents Test Kit (DR1126), a rapid latex agglutination test for the detection of listeria spp from selective culture.
Alternatively, the rapid colorimetric test, Obis mono (ID0600) allows the quick differentiation of L monocytogenes from other listeria spp, or the self-contained, biochemical-based Microbacta Listeria Identification System (12L) (MB1128) provides the definitive identification of pathogenic listeria species in as little as four hours.
The automated Dupont Qualicon Bax system (available from Oxoid in Europe and Australia) uses the latest PCR technology to accurately detect the presence or absence of listeria monocytogenes and listeria spp in food and environmental samples in less than four hours.
In addition, Oxoid offers a full range of listeria enrichment broths and selective media (including the Fraser, Half Fraser, Oxford and Palcam formulations) and, for quality control purposes, the Culti-Loops range of viable, positive and negative control organisms, including L monocytogenes ATCC 7644 (C3970L).
