  • Patent number: 8034552
    Abstract: The present invention relates to virulent (lytic) Listeria monocytogenes phage from the Myoviridae family, preferably P100, alone or in combination with other virulent phages. P100 and the endolysin from P100 can be administered to food products, to the components that will be added to food products, and/or to the infrastructure of the food processing plants within which such food products are processed, or the containers or wraps in which such foods are stored and/or shipped, in order to reduce Listeria monocytogenes contamination. P100 can also be used in the present invention to identify Listeria monocytogenes bacteria present on (or within) foodstuffs, as well as those Listeria monocytogenes bacteria present in the equipment or the general environment of the food processing plants in which the foodstuffs are being processed and in animals infected with Listeria monocytogenes. The phage and the endolysin of the present invention can also be used to treat animals infected with Listeria monocytogenes.

  • Patent number: 5824468
    Abstract: The invention relates to a detection procedure for bacteria of the genus Listeria, comprising the steps:(a) provision of a DNA vector prepared by means of recombination techniques, comprising a genetic system comprising DNA which encodes the expression of one or more proteins, the proteins not being a gene product of bacteria of the genus Listeria and it being possible to determine the presence of the proteins by a detection reaction, and the DNA vector infecting the bacteria of the genus Listeria and it being possible in this way to transfer the genetic system to the bacteria;(b) mixing of the sample with said DNA vector under conditions which allow an infection of bacteria of the genus Listeria by the DNA vector;(c) expression of the detectable proteins in the bacteria of the genus Listeria;(d) detection of the detectable proteins, the presence of bacteria of the genus Listeria being detected,and to recombinant DNA vectors and reagent compositions suitable for this detection procedure.
