Toxoplasa Gondii

[Ailurophobia]

Hello everyone, I read about this protozoan about a month ago and it's been interesting me since. In one book, I read that it has affected about 50% of the world's population and on wikipedia I read only 33%. Whatever the number it's still extremely significant, from my knowledge it has shown to affect behavior so that comes down to over 30% of the world at least under the effect of behavioral changes or any of the parasites plethora of defects. I don't know a lot about this subject, but does anyone know quite a bit about it?
