Listeria Monocytogenes Invading Cardiac Cells (IMAGE) Microbiology Society Caption Listeria monocytogenes cardiac-invasive strain replicating and moving within infected heart cells. The bacteria (red rods) invade heart cells, multiply, and begin to move through the cell by rearranging cell structural proteins (green) that initially coat the bacteria (green and red rods) and then form long comet tails located directly behind moving bacteria.
