How is it possible for anaerobes to be involved in bite wound infections?

Multiple Choice

Most bite wounds are on hands or fingers, which have little tissue and few blood vessels, and are thus fairly anaerobic.

Facultative anaerobes in bite wounds reduce available oxygen in the affected tissue, creating anaerobic conditions.

Bite wounds result in the release of anaerobinases by keratinocytes; these convert oxygen to nitrogen, generating anaerobic conditions.

Although anaerobes are introduced into a wound through biting, they do not multiply in the aerobic tissue and do not contribute to a bite wound infection.

In fact, anaerobes are never involved in bite wound infections; tissues are always well oxygenated, which inhibits any anaerobes from multiplying in them.
