WebNov 16, 2024 · How do Shigella cells move between host cells? 4) The Shigella are able to move through the host cell and spread to adjacent host cells by a unique process called actin-based motility. In this process, actin filaments polymerize at one end of the bacterium, producing comet-like tails that propel the Shigella through the cytoplasm of the host cell. WebNov 1, 2016 · Moreover, actin assembly powers bacterial ABM through the host cytosol, enabling bacteria to reach the cell periphery, where they enter into protrusions that are engulfed by neighboring cells or promote cell–cell fusion. Several genera of bacterial pathogens contain species that are capable of ABM (Table (Table1).1).
