I remember reading about some other parasites or infections that appear to take control over their victims in such a way as to promote the parasite's
thriving.
There is a parasite called
toxoplasma gondii that
infects mammals, most famously cats. During its life cycle it also infects mice and rats. In order to make sure that it gets passed back to the
cats, it cause the infected mice to no longer fear the scent of cats. In fact, infected mice will often favor the areas where cats have been, making
it much more likely that they'll get eaten by a cat and pass the parasite into a cat.
There is some thinking that toxoplasma can affect human brains, resulting in some people becoming "cat ladies". And there appears to be some
connection between toxoplasma and schizophrenia.
There is another parasite that affects cattle, called
Dicrocoelium dendriticum. As
part of its life cycle it is excreted by cattle and then picked up by ants. This parasite (a liver fluke) causes the ants to move to the tips of
grass blades and lock onto the blade with its mandible. That makes it more likely to be eaten by cattle, which then would infect the cattle.
There are some creepy parasites out there. I've never heard of the Glyptapanteles wasp, but I have heard of the
ichneumon wasp. That wasp lays its eggs inside caterpillars after first stinging and
paralyzing the caterpillar. The wasp eggs grow and develop inside the poor caterpillar, eating it from the inside out - kind of like the movie Alien.
The caterpillar doesn't die right away, but can live for days as it's being eaten. Sounds like something out of a horror movie.
