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.

The particular question is, what was responsible? Actually what pathogen, what bacteria formed the Great Plague outbreak in the 17th century? it doesn't seem to come back, so something changed in the way people were living. People say the Great Fire of London in 1666 had something to do with the ending of Great Plague events, but through the scientific studies we can do these days on DNA from samples of these skeletons, we might be able to tell what pathogen is responsible for that outbreak and perhaps why it stopped.
