When the body encounters types of blood it is not familiar with, it makes antibodies to attack it. That's why O- is the universal donor. O means it has neither A or B components, and the negative means it does not have specific receptor proteins on it. That's also why someone AB+ can have any type of blood, because the body is used to A components, B components, and receptor proteins.
