Luis' Memo is a file in Resident Evil 4: Mobile Edition.
There are some parasites that have the ability to control their hosts. It's basic knowledge among biologists but not much is known as to how the parasites do it.
Studying these parasites specifically might give some clues as to how the powers of the Las Plagas work.
And perhaps find out more about the victims of Las Plagas, Los Ganados.
Dicrocoelium: Once the larvae of this parasite migrates to the ant's esophagus, it alters the behavior of the ant.
When the temperature drops in the evening, the infected ant climbs to the top of a plant and clamps onto a leaf using its mandible.
Galactosomum: The larva of this parasite makes its home inside the brain of a fish such as the yellowtail and the striped-beakfish.
Once infected, the fish make their way up to the water's surface where they'll swim until eaten by seabirds.
Leuchochloridium: This parasite's sporocysts develop in the snail's tentacles. The sporocysts are vivid in color and pulsate continually somewhat like a worm.
Surprisingly the infected snail makes its way to the top of a leaf where it is more visible to the eyes of birds, therefore more likely to be eaten.
