Alright, im just gonna jump right in.
There are some parasites that can take control of animals.
For instance Leucochloridium paradoxum which can take control of snails.
Or Spinochordodes tellinii which can take control of grasshoppers.
Although I have not heard of any parasites wich can take control of humans,
there is one that is believed to be able too change our minds in a way.
Its called Toxoplasma gondii and causes the disease toxoplasmosis.
A study has now linked toxoplasmosis to schizophrenia.
Who knows maybe combined with other bugs and/or genetic modification
they can control us too...
I wrote a little about genetic modification, cell making and realistic zombies in my other thread.http://zombiehunters.org/forum/viewtopi ... 20&t=73232
