Francesco Redi (18 February 1626 – 1 March 1697) was an Italian physician, naturalist, biologist, and poet. [1] He is referred to as the "founder of experimental biology", [2] [3] and as the "father of modern parasitology". [4] [5] He was the first person to challenge the theory of spontaneous generation by demonstrating that maggots come ...
A representation by Robert Seymour of the cholera epidemic depicts the spread of the disease in the form of poisonous air.. The miasma theory was the predominant theory of disease transmission before the germ theory took hold towards the end of the 19th century; it is no longer accepted as a correct explanation for disease by the scientific community.
However, although the idea of spontaneous generation had been in decline for nearly a century, its supporters did not abandon it all at once. As James Rennie wrote in 1838, despite Redi's experiments, "distinguished naturalists, such as Blumenbach, Cuvier, Bory de St. Vincent, R. Brown, &c." continued to support the theory. [45]
A key proponent of the germ theory of disease. [2] 1850–1934 Fanny Hesse: German Developed agar for use in culturing bacteria. [2] [6] 1851–1931 Martinus Beijerinck: Netherlands Discovered the first virus as well as bacterial nitrogen fixation and sulfate reduction. 1885–1948 Marjory Stephenson: British Pioneer of bacterial metabolism ...
Thus, Pasteur refuted the theory of spontaneous generation and supported the germ theory of disease. [17] Robert Koch showed that microorganisms caused disease. In 1876, Robert Koch (1843–1910) established that microorganisms can cause disease.
This began the path to germ specificity within the theory. [49] Louis Pasteur's contemporary Robert Koch devoted much of his scientific study to discovering certain pathogens and connecting them to specific diseases. These scientists were often in competition with one another and so the Koch-Pasteur rivalry is a well-known part of germ theory's ...
At the time the "germ theory" of disease had not yet obtained general acceptance, and Koch's announcement was received with considerable skepticism, particularly after it was found that similar "comma bacilli" could be found at times in the feces of persons not suffering from cholera, and often in all sorts of other environments - well and ...
That was called heterogenesis, commonly mistaken by abiogenesis or spontaneous generation, and despite of not being exactly so, it is still not germ theory of disease. Redi himself also did not discarded heterogenesis, even though he thought that maggots in meat came from eggs laid there, he did not applied the same logic with gall insects ...
