Parasite Collector

Book excerpt: Some people do their jobs in Arctic blizzards or fierce storms on the high seas. For some people, crawling through dark caves, climbing into sewers, searching through animal droppings, or even driving a car off a cliff is all in a day's work. Who does jobs like these, why do they do them, and how do they stay safe doing them? You'll find out in Dirty and Dangerous Jobs. Scientists who look for parasites need strong stomachs. To find tiny parasites that can cause serious illness, they pick through the fur of dead animals or the feathers of dead birds. They cut open dead animals and look through animal waste. Why do they do such things? Parasite collectors are trying to save lives by finding cures for deadly diseases. Book jacket.
