Caption

This 25-second video shows macrophages derived from mice and infected with the bacterium Francisella Tularensid. The white arrow indicates an infected cell that undergoes a sudden flash, indicating compromised host organelles, subsequent hyper-replication of the bacteria, and eventually cell death. The brown arrow indicates an uninfected 'bystander' cell that also is being killed by a similar mechanism. Images were taken every 20 minutes over 30 hours.
