-
Listeria process step 1
Listeria enters the body,
usually through contaminated drink or food.
-
Listeria process step 2
Listeria triggers its own phagocytosis by a host cell, typically in the gallbladder.
-
Listeria process step 3
The intracellular bacterium escapes the phagosome.
-
Listeria process step 4
The bacterium reproduces
within the phagocyte. Some of the
mRNA in a Listeria cell activate at 37ºC, so the bacterium reproduces more rapidly inside human cells.
-
Listeria process step 5
The bacterium polymerizes the host cell’s actin filaments
