Intracellular Pathogens
A pathogen or infectious agent is a microorganism such as a virus, bacterium, prion, or fungus that causes disease in its host.

Extracellular Immune Avoidance
A pathogen's success depends on its ability to evade the host's immune responses.

Regulating Virulence
Virulence regulation is a combination of the specific traits of the pathogen and the evolutionary pressures that lead to virulent traits.

Portals of Exit
Pathogens must have a way to be transmitted from one host to another to ensure their species' survival.
