Dr. Jenkins...aka Dr. Exotic is one of the leading exotic vets in the country. I have had the pleasure of his advice in my journeys in rescue.
Pasteurella multocida is the pathogen (bacteria) that is responsible for what had traditionally been known as "snuffles"...and many of you know that I hate that term. In a rabbit, most often the condition manifests itself in the upper respiratory system and gives the "cold" (rabbits don't get colds) symptoms we all know. It is also responsible for nearly all of the non-trauma induced head tilt (wry neck). It can also invade any body organ and is usually also found in parts of dental/head abscesses. It can be most challenging to contain.
Is is zoonotic...yes, people can get pasteurella. But it is found in the respiratory tracts of nearly every warm blooded mammal....including humans. Unless the person is very young or very old or that their immune system has been compromised, a human's immune system can usually handle any systemic infection quite easily. And we can also take some antibiotics that rabbits can't.
