Infection resistance - The ability of a host to prevent an infection from occurring. 

Infection tolerance - The ability of a host to minimize the harm once an infection has occurred. 

Parasite load - The number of parasites of a given species that an individual host can harbor.

Vertical transmission - When a parasite is transmitted from a parent to its offspring.
