any disease-producing agent (especially a virus or bacterium or other microorganism)
Any organism or substance, especially a microorganism, capable of causing disease, such as bacteria, viruses, protozoa or fungi. Microorganisms are not considered to be pathogenic until they have reached a population size that is large enough to cause disease.
A pathogen or infectious agent is a microorganism—in the widest sense, such as a virus, bacterium, prion, or fungus—that causes disease in its host. The host may be an animal, a plant, or even another microorganism. There are several substrates including pathways whereby pathogens can invade a host. The principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. Diseases caused by organisms in humans are known as pathogenic diseases. Some of the diseases that a pathogen can cause are smallpox, influenza, mumps, measles, chickenpox, ebola and rubella. Not all pathogens are necessarily undesirable to humans. In entomology, pathogens are one of the "Three P's" that serve as natural or introduced biological controls to suppress arthropod pest populations.
