Be warned that parasites are generally pests, and in normal circumstances don't typically cause serious problems for a host.
However when crossing hosts signals can get crossed and they can cause serious health problems like eating your retina, brain, hearts, etc. Be very careful with parasites that aren't evolved for humans.
