This may well have been because of the different personalities of the two scientists. He realized that living cells produce new cells through division. 30 seconds . microbiology, study of microorganisms, or microbes, a diverse group of generally minute simple life-forms that include bacteria, archaea, algae, fungi, protozoa, and viruses.

Although the meat in all of the flasks putrefied, he found that only in the open and uncovered flasks, which flies had entered freely, did the meat contain maggots. 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. Francesco Redi, (born Feb. 18, 1626, Arezzo, Italydied March 1, 1697, Pisa), Italian physician and poet who demonstrated that the presence of maggots in putrefying meat does not result from spontaneous generation but from eggs laid on the meat by flies.

Francesco Redi was a 17th-century Italian scientist whose most notable contribution to scientific knowledge was his work discrediting the notion that life can come from non-living things. In the 19th century, Louis Pasteur expanded on Redis experiments to disprove spontaneous generation conclusively. It's interesting to note that despite his experiments, Redi believed spontaneous generation could occur, for instance, with intestinal worms and gall flies. Surgery used to be as dangerous as not doing anything at all, but once. For the snakes he observed, he established that venom must be injected into the victims bloodstream to be deadly.
