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.
Place the unwrapped lobster tail on a microwave-safe plate and defrost it for 1 minute on the defrost setting, or at 30 percent power. After 1 minute, check the tail and rotate it if necessary. Continue to thaw at 30-second intervals until the lobster tail is pliable but still slightly frozen. Avoid over-thawing in the microwave, which will begin to cook the tail. After thawing, use the lobster tail within 4 hours to ensure the best quality. Lobster tails aren't suitable for refreezing after you thaw them, regardless of the defrosting method.
