Parasite species varied strongly in their effects on
host fecundity, host survival, host density reduction, and the frequency with which they drove host populations to extinction
. The fewer offspring an infected host produced, the lower the density of an infected host population.
What are the effects of a parasite?

What does it mean if a parasite is host specific?
In simple terms, host specificity can be defined as
the number and identity of host species that are used by a parasite population
. Parasites that are highly host-specific will occur in a single host species, whereas generalist parasites will be dispersed unequally among individual hosts from several different species.
Why is it important for us to study parasite host relationships?
These interactions may be synergistic or antagonistic and thus produce diverse effects in infected humans and animals.
Interactions among parasites strongly influence parasite dynamics
and therefore play a major role in structuring parasite populations (both within and among hosts) as well as host populations.
