There is some evidence suggesting that bacterial infections can play roles in different behaviors, so there's some truth to that.
Another semi-related interesting fact: you share the same gut flora with those you live with. This comes in handy when treating life threatening C diff colitis using fecal transplant, but it leaves you wondering how the gut flora get there in there first place. Kind of gross, if you think about it.
