SPECIFICITY OF A RAPID METHOD FOR THE IDE NTIFICATION OF LISTERIA-MONOCYTOGENES - THE MONO CONFIRM TEST

The Mono Confirm test is a micromethod based upon four biochemical rea ctions for the identification of Listeria monocytogenes in 24 hours. T he test must be performed with Listeria strains. The enzyme D-aminopep tidase allows the differentiation between L monocytogenes and other Li steria species. To study the specificity of the Mono Confirm test, 133 Listeria strains which came from food products, human or animal sourc es were examined. Mono Confirm test enabled good identification for ai l L monocytogenes (68 strains); 64 out of 65 non monocytogenes Listeri a strains were recognized as Listeria non monocytogenes.
