Koch developed the Koch Postulates, which, if proven, demonstrate that a given microbe causes a disease. (see related link).
Girolamo Fracastoro proposed epidemic diseases are caused by transferable seed-like entities that transmit infection by direct or indirect contact. Agostino Bassi was the first person to prove that a disease was caused by a microorganism.

∙ 8y agoLouis Pasteur (France: 1860s) discovered (by using a swan-necked flask) that germs cause disease. Before he made this discovery, doctors had noticed bacteria, but they believed it was the disease that caused the bacteria (the so-called theory of 'spontaneous generation') rather than the other way round.

What are scientists trying to identify when they use koch's postulates?
the cause of a disease
What is disease-causing microorganisms called?
Pathogens.
Koch's postulates are rules for?
Koch's postulates serve as criteria for microbiological diagnosis of specific diseases. They more specifically try to find out what pathogens are responsible for the disease by seeing if they are only found in diseased individuals, if they can be isolated, if they can make a healthy organism sick if introduced, and if they are able to be re-isolated and found identical to the first isolated group.
What is Koch's rule?
Robert Koch (1843-1910) was a German physician and microbiologist who showed that "the key to the identification of bacterial pathogens was the isolation of pure cultures." What are Koch's postulates? In the course of his studies of anthrax and tuberculosis, Robert Koch formulated rules of procedure for proving that a certain microorganism is the cause of a particular disease. These rules, known as Koch's postulates, are still used today: 1. It must be shown that the microorganism in question is always present in diseased hosts. 2. The microorganism must be isolated from the diseased host and grown in pure culture (i.e., in a culture containing only that one species of microorganism). 3. Microorganisms obtained from the pure culture, when injected into a healthy, susceptible host, must produce the disease in that host. 4. Microorganisms must be isolated from the experimentally infected host, grown in pure culture, and compared with the microorganisms from the original culture.
A piece of equipment is sterile if it contains 1- no microorganisms 2-only microorganisms that do not carry disease 3-only normal bacteria?
1. No organisms.
What theory provides the explanation that diseases are caused by microorganisms?
Koch's Postulates provide a theory that one microbe causes one disease. So that also fits that diseases are caused by microorganisms. This was just a little over 100 years ago.
What are nonharmful and are not disease-producing microorganisms?
Nonpathogens are nonharmful and are not disease-producing microorganisms.
What was the name of the scientist who during the 1860's developed a heating process that killed microorganisms to prevent disease?
Louis Pasteur
Pathogens are micro-organisms that fight disease?
No. They are microorganisms that cause disease.
What is a microorganisms that cause disease?
Microorganisms that cause disease are known as pathogens, such as bacteria, viruses and fungi.
Why microorganisms associate with disease?
Microorganisms are associated with disease because they are the common cause of disease. For centuries it was believed that bad smells or miasma was the cause of disease. This attitude later changed as microorganisms were discovered and proved to be the actual source of disease.
What is the disadvantages of microorganisms?
The disadvantage of microorganisms is that many of them cause disease.
What is disadvantages of microorganisms?
The disadvantage of microorganisms is that many of them cause disease.
What are scientists trying to identify when they use koch's postulates?
the cause of a disease
What is the theory that microorganisms can cause disease?
The germ theory of disease.
Is heart disease caused by microorganisms?
No
Do microorganisms cause disease?
Yes
