My wife contracted a case of "plague" from the Pasteurella pestis (aka Yersinia pestis) minor organism. Her Red Tail hawk had picked it up while hunting in the field. The hawk passed it to my wife. Both were treated and recovered. We were lucky that the veterinarian diagnosed the plague infection in time for rapid treatment. A hot strain of the "real thing" can kill in hours. Especially if passed as pneumonic plague from coughing/sputum vs rat flea bites.
