I don’t know about snakes, but I do know that anticoagulants in saliva do nothing to prevent bacteria.that isn't true; if it was I would have been dead. I have gotten bit probably 50+ times in the past couple of years (I was going out of my way to catch them, they were just defending themselves and calmed down once they realized I wasn't going to hurt them). There is very little chance it will even get infected as they have an anticoagulant in their saliva which results in very little bacteria actually getting left behind. they actually have relatively clean mouths to begin with as well.
Anticoagulants are things that hinder blood clotting.
