Detection of Listeria spp. with a monoclonal antibody-based enzyme-linked immunosorbent assay (ELISA) by R.R. Beumer, E. Brinkman.
A monoclonal antibody-based ELISA method for the detection of Listeria spp. was evaluated its ability to detect this organism in artificially contaminated foodproducts. When enrichment broth contained 10 6 cells/ml or more, independent their physiological state, a positive reaction obtained: Some influence product and/or competitive micro-organisms could be detected. However assure successful application efficient procedures are necessary, especially when present at low levels.
