A Molecular Marker for Evaluating the Pathogenic Potential of Foodborne<i>Listeria monocytogenes</i>

Abstract

This study demonstrates the critical role of internalin in the pathogenesis of human listeriosis. It provides a molecular explanation for the predominance of serovar 4b among clinical strains and supports the usefulness of studying the expression of internalin as a marker of virulence in humans.
