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.
Lobsters can live up to 48 hours out of circulating salt water if they are properly refrigerated. Lobsters donât need to be jumping out of the box to be fresh and good eating. They should, however, be checked upon arrival. If they are not moving, it is best to cook them immediately.
