How does Listeria monocytogenes survive with nothing to live on?

Try going for a couple of weeks without food and see what shape you're in, or if you're around at all by then. Let some dangerous bacteria do the same thing and there's a chance they may do more than survive; they can grow stronger and remain as virulent as ever.

Bacterial biofilms

In one of the first potential applications of synthetic biology, an emerging field that aims to design and build useful biomolecular systems, researchers from MIT and Boston University are engineering viruses to attack and destroy the surface biofilms that harbor harmful bacteria in the body and on industrial and medical devices.

Simple equations track Listeria trails

Circles, slaloms, figure eights, and loop-the-loops , biologists studying the motion of Listeria monocytogenes sensed that these paths were related, but they didn't have a good way to define what fit in and what didn't.

Using gamma radiation preserves T-cell responses in bacterial vaccine

Using gamma radiation to inactivate bacteria for the preparation of vaccines, instead of traditional heat or chemical methods of inactivation, appears to create a vaccine that is more effective than so-called "killed" vaccines against disease, and has the added advantage of a longer storage life than "live" vaccines.

Irradiation preserves T-Cell responses in bacterial vaccine

Findings could result in more potent vaccines that are relatively inexpensive to produce, easy to store, and that can be transported without refrigeration.
