Vanderbilt researchers have identified a new signaling system that anthrax bacteria uses to infect its host.

Understanding how bacteria become resistant to quinolone antibiotics could guide strategies for developing new antibacterial drugs.

Scott Hultgren, Ph.D., an expert on the interactions between bacteria and human hosts, will deliver the next Flexner Discovery Lecture on Thursday, March 7.

Vanderbilt investigators report new insights to the workings of calprotectin, an immune system protein that “starves” bacterial pathogens of the metal nutrients they require.

It may be possible to fight hospital-acquired pathogens like Acinetobacter baumannii by targeting the bacterium’s need for the nutrient metal zinc.

Study adds evidence for infectious agents’ role in sarcoidosis, an inflammatory condition that can lead to respiratory failure and death.

The stomach bug Helicobacter pylori increases forms of a protein that promote tumor development, perhaps explaining how it elevates risk for gastric cancer.
