Movement and Dispersal

The listeria bacteria travel at room temperature using peritrichous flagella (many flagella surrounding the outside of the cell that allow for easier travel). The bacteria use the flagella, a whip-like tail structure, to thrust themselves. When it is present in body temperature it doesn't travel using the peritrichous flagella instead it takes over the host cell’s cytoskeleton and creates the actin tail using the cell's protiens. Then it travels around the cytoplasm of the cell and into other cells.

The picture shows and example of the peritrichous flagella of listeria.

It is also able to infect many different parts of a body. Once leaving the digestive tract, it enters the blood stream. It uses the blood stream to transport to the nervous system and well as the fetus (in pregnant women).
