Newly found sensing system enables certain bacteria to resist human immune defenses

...sitive bacteria include agents that cause anthrax, strep throat, flesh-eating disease and various types of food poisoning. In gram-negative bacteria—such as those that cause plague and salmonellosis—a sensory and gene regulation system named PhoP/PhoQ protects invading bacteria, and scientists believe i...

Infection detectives use disease 'fingerprints' to track common infections in children
