I'm an anesthesiologist by specialty, with experience as a GP/Family practitioner; the answer to your first question is above my medical pay grade.

In regard to the second, I can say this: in the ER, a human bite is considered FAR more dangerous than a dog bite, because the human mouth has more — and more dangerous — pathogens. The mouth is much dirtier (not cleaner) than skin.
