    AgResearch, Hamilton, New Zealand
    Int J Food Microbiol 73:71-81. 2002
    ..The use of nisin and listeriophage has potential to control L. monocytogenes in foods but a further understanding of the interactions in this complex system needs to be achieved before it could be applied practically...

    Curr Microbiol 46:461-6. 2003
    ..The results of this study indicated that the relative importance of the sigB gene in the stress response is not the same in all strains of L. monocytogenes, and this difference may be specific to serotype groupings within the species...
