THE PATHOGENS
 

Bacteria and parasites are hard to kill. Even harder when they hide inside of our cells. Learn more about the intracellular pathogens studied in our laboratories.

 
THE SCIENTISTS
 

A collection of research labs at IU have taken up the challenge to study microbes that replicate inside of our cells. Meet the scientists who study these invaders.
