A disease-causing microorganism is called a "pathogen". It can be a bacteria, virus, or fungus.
Not directly, but the infectious microorganism that causes the disease may produce a toxin that is the cause of some of the disease's symptoms. Not every disease causing microorganism produces a toxin.
Pathogenic means "having the ability to cause disease".
Almost all microorganism can cause disease.those which cause disease are known as Pathogens.
A microorganism is considered to be a cause of the infection if it is either the only or predominant microorganism that grew, if it grew in large numbers, or if it is known to produce infection.

Koch's postulates, named for Dr. Robert Koch (1843-1910), are the four principles that define a disease as caused by a specific microbe.Briefly they are :The microorganism is present in large numbers in diseased hosts, but not in healthy ones.The microorganism can be isolated as a culture.The microorganism causes the disease if introduced into a healthy host.After infection of a new host, the identical microorganism can again be isolated.* The term primary Koch infection is a reference to childhood tuberculosis usually confined to the lymph nodes and not contagious.
