He stated that disease cannot be caused by bad air or vapor, but it is produced by the microorganisms present in the air. Spontaneous generation, a theory that maggots, fleas, worms and other living organisms developed from inorganic or dead organic matter, was the prevalent viewpoint of scientists for around 2,000 years, since Aristotle first posited a description of the phenomenon. 9 What did Redi discover about spontaneous generation? What did Redis experiment with flies prove? A strong opponent of spontaneous generation, the Italian physician Francesco Redi set out in 1668 to demonstrate that maggots did not arise spontaneously from decaying meat.

The main aspects were to solve the controversy over a spontaneous generation which includes experimentations mainly of Francesco Redi, John Needham, Lazzaro Spallanzani, and Nicolas Appert, etc, and to know the disease transmission which mainly includes the work of Ignaz Semmelweis and John Snow. Francesco Redi, as far back as 1668, had set out to refute the idea of macroscopic spontaneous generation, by publishing the results of his experimentation on the matter. Maggots only developed.
