چکیده

T his story begins in the early 1880s. The germ theory of disease was fairly well established, although some experts continued to challenge it. For example, Theodor Billroth (1829– 1894) of Vienna, often called the founding father of abdominal surgery, did not immediately accept the germ theory, but later embraced the concept and became very successful in many pioneering surgeries. Another critic was Max von Pettenkofer (1818–1901) of Bavaria, a noted experimental hygienist. In 1892, Pettenkofer openly challenged Robert Koch (1843– 1910) on his theories about Vibrio cholerae by drinking the contents of a flask containing the cholera bacillus. The flask had been given to Pettenkofer by Koch himself, but Pettenkofer did not contract cholera! Perhaps the biggest critic was the famous physician Rudolph Virchow (1821–1902) of Berlin. Virchow believed that diseased cells arose only from other diseased cells, and strongly opposed the germ theory of disease. Other skeptics could be cited, but the important point is that Koch was working in a controversial area of medicine and experimental research in the late 1800s.

For example, in the germ theory various nonequivalent criteria have been proposed for establishing that specific micro-organisms cause particular diseases.' Perhaps the most famous criteria are the conditions known as Koch...

For over a century, Koch's postulates have been accepted as being as close to proof as is likely to be achieved. If any microorganism satisfies these postulates, then most microbiologists would accept that the organism was indeed pathogenic. Koch's postulates are as follows: (...

Whither Koch’s Postulates?

S pecific etiology was one of the most powerful and productive ideas in the entire history of medicine. Replacing a shadowy intellectual landscape of humors and miasmata with the notion that particular diseases had particular causes, it marked the beginning of the end for both diagnostic imprecision and clinical impotence. Within the domain we now recognize as microbiology, the prime mover was,...
