Two highly specific primers for Listeria monocytogenes were used to yield from foods such as milk, soft cheese and meat, PCR products that were cleaved with the restriction enzyme HindIII.

Abstract

Two highly specific primers for Listeria monocytogenes were used to yield from foods such as milk, soft cheese and meat, PCR products that were cleaved with the restriction enzyme HindIII. The fragments generated allowed a distinction between two groups of L. monocytogenes serovars: serovars 1/2a and 1/2c cluster in one group and serovars 1/2b, 3b and 4b in the other subgroup. Since this procedure can be completed in 24 h, an epidemiological association between human disease and suspected sources can be rapidly confirmed at the subgroup level in the laboratory.
