History of medicine - Germ Theory, Microbes, Vaccines: Perhaps the overarching medical advance of the 19th century, certainly the most spectacular, was the conclusive demonstration that certain diseases, as well as the infection of surgical wounds, were directly caused by minute living organisms. This discovery changed the whole face of pathology and effected a complete revolution in the ...
Koch’s “one microbe, one disease” concept was the culmination of the 19th century’s paradigm shift away from miasma theory and toward the germ theory of disease. Figure 1.1.4.2.2: (a) Joseph Lister developed procedures for the proper care of surgical wounds and the sterilization of surgical equipment. (b) Robert Koch established a ...

Also called the pathogenic theory of medicine, germ theory was first suggested in the fourth century BC by Greek philosopher Democritus ...
He established the germ theory of diseases in 1867–1868 with the discovery that two diseases of silkworms, pébrine and flacherie, were contagious and infectious ( 121 ). These and subsequent discoveries of animal and human pathogens met with violent opposition, particularly from veterinary surgeons and physicians.
Nov 18, 2022 · His first foray into applying the germ theory of disease came during the late 1860s in response to a decline in French silk production because of diseases afflicting silkworms.
