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.
Lobster should be cooked live and eaten right away as the meat can go bad very quickly. If you need to keep previously frozen lobster for a short period, steam it as soon as possible after thawing and just reheat in the oven when ready to eat. It should then be eaten within a day or two at most. Enjoy!
