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.

The biosynthesis of chlorophylls and heme begins with the synthesis of δ‐aminolevulinic acid (ALA) from glutamic acid. 

Two molecules of ALA react to yield porphobilinogen (PBG). 

Four molecules of PBG form the ring structure of protoporphyrin IX, the common branch point for the synthesis of heme and chlorophyll. 

To make chlorophyll, a magnesium chelatase inserts Mg into the protoporphyrin IX ring
