Not all diseases are caused by microbes. The theory of one microbe causing one disease was proven long ago. We know now that it is more complex that that now.
To prove this, see what microbes will grow from each person who has a similar disease and if these microbes are the same microbe, this microbe caused this disease. However, the proof would need thousands of cases to "cement" the cause.
The germ theory of disease.
Yes, some bacteria cause disease, for example. A general term for microorganisms that cause disease is "pathogens."

The germ theory of disease is the theory that microorganisms are the cause of disease. They spread when the host is exposed to the pathogen by various means.
Nonpathogens are nonharmful and are not disease-producing microorganisms.
No. They are microorganisms that cause disease.
Microorganisms that cause disease are known as pathogens, such as bacteria, viruses and fungi.
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.
The disadvantage of microorganisms is that many of them cause disease.
