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.
The best way to thaw frozen lobster tails is by letting them thaw slowly in the fridge for 24 hours. If you donât have 24 hours to wait, seal the frozen tails in a plastic bag and run them under cold water for 30 to 60 minutes. Microwave-thawing is tricky because the meat will toughen up if it starts to cook.
