VIDAS® UP Recombinant Phage Technology Delivers Unprecedented Specificity and Sensitivity for Rapid and Reliable Testing of Listeria spp

Marcy l’Etoile, France – November 6, 2012 — bioMérieux, a world leader in the field of in vitro diagnostics, today launched a new, innovative food safety testing method, VIDAS® UP Listeria (LPT). This new solution utilizes recombinant bacteriophage (phage) proteins, which offer best-in-class specificity and sensitivity for the targeted and rapid detection of Listeria species in food and environmental samples. VIDAS LPT complements the company’s VIDAS® UP E. coli O157 (including H7) and VIDAS® UP Salmonella, all based on phage technology.

The new VIDAS LPT assay is one of the most rapid and easy-to-use Listeria spp screening tests for food and environmental samples. Based on phage protein technology, it is able to detect low contamination levels and provides an extremely simple enrichment protocol, which reduces laboratory hands-on time, and delivers next-day results as compared to reference methods, which require up to five days.

VIDAS LPT has already been ISO 16140 certified by AFNOR for all human foods and production environment samples. AOAC-RI validation has been initiated.
“bioMérieux is committed to helping customers ensure food safety worldwide,” said Jean-Marc Durano, Corporate Vice President, Industrial Microbiology Unit. “VIDAS LPT is a new member of the VIDAS UP range that simplifies agri-food laboratories’ workflow, delivering rapid information to optimize the overall efficiency of food production.”

Members of the genus Listeria are ubiquitous, and Listeria monocytogenes is pathogenic for humans. Listeria have been isolated from various food products including dairy products, meat, vegetables, and seafood, as well as from environmental samples taken, in particular, from food processing plants. Listeriosis in humans may cause pathologies such as meningitis, septicaemia, encephalitis and abortions. People at risk include pregnant women, neonates, immunocompromised patients, and the elderly.

About Bacteriophages
Bacteriophages, some of the most abundant life forms on earth, are highly specific viruses programmed exclusively to identify and infect host bacteria. Phages have co-evolved with bacteria for more than a billion years and are able to survive in the most extreme environments including soil, animal waste and intestinal tracts. Research shows that bacteriophages offer a number of advantages, such as superior specificity and superior binding, when used in microbiological test systems. Phage proteins have been proven to provide robust performance in many different applications, even when challenged with the most demanding and complex food matrices.
Licensed exclusively to bioMérieux, the recombinant phage technology was developed by the German biotech company Hyglos GmbH.
