I've seen other studies similar to this one on other mammals, one on Moose that were infected with roundworm. The moose was not afraid of the attacking wolves, and became much easier for the predator to remove.
I think I saw it on the discovery channel. I'm sorry I can't site it.
When you consider the very long time that we have all evolved together, then
parasites are going to use chemical means to change the behavior of the host animal, including humans.
I also saw a study on human behavior that indicated that parasitic infections made human women less suspicious of strange men, and more promiscious. So much for 'free love'! If you consider that a lot of
parasite are going to be transmitted by sexual behavior, then they will also affect the host in that way also. Again, I can't remember the source, it may have been
parasite Rex, which is a really interesting book, and readable as well.
