History of microbiology. USA. Francesco Redi presented a cell theory which helped to discredit the idea that living things can come from non-living things. Italian physician Francesco Redi performed an experiment in 1668 that proved that maggots DO NOT spontaneously generate on rotting meat. Virchow used the theory that all cells arise from pre-existing cells to lay the groundwork for cellular pathology, or the study of disease at the cellular level. With roots in the mid-17th century, multiple scientific scholars and researchers of the day contributed to the tenets of classical cell theory, which postulated that cells represent the basic building blocks of life; all life consists of one or more cells, and the creation of new cells occurs when old . Florence: L. S. Olschki. Francesco Redi's main contribution to biology was proving that maggots did not erupt spontaneously from rotting meat, but were deposited there in the eggs of flies.

Redi had been the first person to use experiments to show fellow scientists the path, but it took them a long time to follow it to its natural conclusion. 10 How did Redis work impact the field of toxicology? microorganisms that grow in a culture broth or that ferment beers or . Through these observations, he was able to demonstrate the mechanics of pollen through the use of his papillae. Redi was famously known for his work on spontaneous generation or abiogenesis. His scientific work resulted in a number of significant milestones: he showed that flies breed and lay eggs and do not, as was popularly believed, spontaneously generate; his microscopic examination of parasites marked the founding of modern parasitology; and in studying chemical treatments to kill parasites, he devised and performed the first controlled experiments in scientific history.

The field of molecular biology made great strides in understanding the genetic code, how DNA is regulated, and how RNA is translated into proteins. New York: McGraw-Hill. Encouraged by the successful prevention of anthrax by vaccination, Pasteur marched ahead towards the service of humanity by making a vaccine for hydrophobia or rabies (a disease transmitted to people by bites of dogs and other animals).

John Turberville Needham dedicated himself to the Roman Catholic religion and was ordained in 1738. Francesco Redi's was an innovative scientist, physician, and poet. Spallanzani had many findings against epigenesist and the role of sperm which he identified as "animalcules" in generation (1).

He stated that disease cannot be caused by bad air or vapor, but it is produced by the microorganisms present in the air. What was Francesco Redi contribution to microbiology? At that time, Redi had proved that a dead maggot or fly couldn't produce new maggots or flies when they were placed on rotten meat inside a sealed jar.

In 1668, in one of the first examples of a biological experiment with proper controls, Redi set up a series of flasks containing different meats, half of the flasks sealed, half open. The relative simplicity of the microorganism, their short life span and the genetic homogeneity provided an authentic simulated model to understand the physiological, biochemical and genetical intricacies of the living organisms. German biochemist Paul Ehrlich (1854-1915) developed a chemical theory to explain the body's immune response and did important work in chemotherapy, coining the term magic bullet. He was also credited for starting a research project that led to the invention of the autoclave device in 1879. And, as Galileo had done in physics, he refuted the biology of Aristotle, who had claimed that snakes are killed by human spittle.
