A practitioner took a scab from someone with a mild case, made an incision in the skin of a healthy person, and infected that person with the scab. Sheep-scab is a loathsome skin disease due to an acarian parasite.
I did find this link, but I don't think it will help out much, because there is nothing on the internet about it, other than this. http://en.allexperts.com/q/Wild-Animals-705/frozen-crab-life-thawed.htm. Or you can go to this link. Its about frozen lobsters coming back to life after thawed.
But away from the dinner table, lobsters may actually hold the secret to a long, healthy â and possibly even eternal â life. For this crustacean is one of a handful of bizarre animals that appear to defy the normal ageing process. While the passing years bring arthritis, muscle loss, memory problems and illness to humans, lobsters seem to be immune to the ravages of time. They can be injured, of course. They can pick up diseases.
