Horrifying rumors about the number of dust mites found in a typical pillow abound, but this volume on parasites provides the official science behind those stories: pillows that are two or more years old owe ten percent of their weight to mite feces and dead mites. Dust mites are one of several parasites profiled in this fascinating work, which also covers mosquitoes, fleas, lice, and worms, both historically and in our contemporary world. Threats to humans and animals posed by parasites are examined in depth, but information is also included on positive parasitic associations, such as hookworms’ ameliorative effect on symptoms associated with inflammatory bowel disease. Concise explanations, memorable anecdotes, and numerous black-and-white photographs and illustrations (some satisfyingly disgusting for those who relish that element of the topic) combine in this thorough volume which includes titles for further reading, a bibliography, and internet resources. (Ages 10–14)

Award winner Albert Marrin answers the question: "What's eating you?" - literally

From nonfiction master Albert Marrin, here is the shocking story of the longest running war of all time: man versus parasite. From fleas, ticks, lice, and bedbugs to worms, mites, leeches, and maggots, Marrin explains what parasites are, how they invade our bodies, and their effects for good or ill. At their best, parasites have saved limbs and lives; at their worst, they've been responsible for the deaths of billions of people and altered the course of human history. With photographs and illustrations throughout, this exploration of the hidden world exposes the creatures responsible for making our skin crawl - since the beginning of time.
