WebMcGrath et al.[2] measured the velocity of Listeria cells overexpressing the ActA protein in a milieu of a frog egg extract supplemented with monomeric actin. In previous work [8], these authors found that motile Listeria cells displayed very little side-to-side movement, and moved forward in a series of 5 nm steps. WebMany pathogens can invade non-phagocytic cells and survive within a membrane-bound compartment. However, only a small number of bacteria, including Listeria monocytogenes, Shigella flexneri,...

Finally, we present ABM through a new lens by comparing motility mechanisms between related species of Listeria, Burkholderia and Rickettsia. Through … WebJul 7, 2011 · Because Listeria monocytogenes are intracellular pathogens, virulence is associated with the ability of bacteria to move into host cells by polymerization of host cell actin at one end of the bacterium, which helps them propel through cytoplasm. Flagellar motility is used more for spread of the bacteria outside the host environment (9, 13).
