Redi also studied parasites in great detail, writing descriptions and creating illustrations in books and treatises. The Theory of Spontaneous Generation. He compared the health outcomes for animals given chemical treatments for their parasites versus animals kept under the same conditions but given no treatment for their parasites. Having observed the development of maggots and flies on decaying meat, Redi in 1668 devised a number of experiments, all pointing to the same conclusion: if flies are excluded from rotten meat, maggots do not develop. ^ Francesco Redi.
