Listeria monocytogenes is a gram positive, rod shaped intracellular pathogen. Its the most virulent foodborne pathogen and is responsible for human listerios is on a large scale. In this study, Listeria monocytogenes bacterium was isolated from varied sources including dairy food materials like cheese and other milk products and human infections. These isolates were cultured and allowed to proliferate in brain heart infusion broth. Isolates were screened for their proliferation and ability to infect other cells by assessing their intercellular spread and plaque formation by cell plaque assay in a murine macrophage cell line and virulence potential was determined by ANOVA methodology. Among all isolates, human origin Listeria strains demonstrated highest virulence potential.
