Not all the molecular players are known yet, nor how their relative roles determine whether the virus becomes dormant, but Weinberger said his and Shenk's results lead them to think they are on the rig...

Protein discovery targets antibiotic-resistant bacteria

...dying sensory pathways used by bacteria that enter our bodies and move from the stomach into the gastro-intestinal tract. “If we can block the sensory pathway, then the bacteria can’t adapt to that change in their environment, and won’t be able to infect,?says Dr. Martin.
