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.
Not sure about lobsters but I know cockroaches can be frozen in LN2, liquid nitrogen (a very good hard freeze but also very quick) and will thaw out and crawl away (not exactly in perfect condition but they can crawl away). It has to do with many factors including how quickly the water in the body freezes.
