WebShigella infection and host cell death: a double-edged sword for the host and pathogen survival. In response to bacterial infection, epithelial cells undergo several types of cell death, including apoptosis, necrosis, pyroptosis, and necroptosis, which serve to expel the … WebApr 9, 2024 · 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 …
