Listeria monocytogenes is a rod shaped, gram positive intracellular pathogen. It is a food-borne pathogen commonly spread by infestation with decaying vegetables, soils, animal faeces, sewage and water and is responsible for the zoonotic occurrence of human listeriosis. In this study, Listeria monocytogenes was isolated from varied sources including cheese, milk and milk products, vegetables, meat and sea food and human infections. These isolates were cultured and allowed to proliferate in brain heart infusion broth. Isolates were then screened for their invasive potential and ability to infect other cells in Ptk cell line by in vitro cell culture assay. Preparations were then observed under oil immersion and examined for intracellular Listeria monocytogenes. Amongst all isolates, human origin Listeria isolates showed highest invasive potential.

Keywords: Listeria monocytogenes, in vitro cell culture assay, Ptk cell line
