What does pathogene mean?
A pathogene is an organism capable of causing disease. The term is used especially for disease-causing microorganisms such as bacteria, viruses, fungi, and parasites, although it can also refer to a larger organism that harbors or transmits pathogens. In scientific and medical writing, a pathogene may be identified by its species, host range, mode of transmission, and the disease or condition it produces. The word is less common than pathogen, which conveys the same meaning and is the usual choice in contemporary English. Pathogene nevertheless remains useful in formal biological descriptions, particularly when discussing emerging, human, animal, or plant pathogens. It should not be confused with pathology, which is the study or description of disease, or with pathogenesis, which is the process by which a disease develops. The distinction between the agent and the condition it causes is central to accurate medical and biological usage.
nounA pathogen is an organism, especially a microorganism such as a bacterium, virus, fungus, or parasite, that can cause disease. The less common term pathogene is used chiefly in biological and medical contexts.
- An organism, especially a bacterium, virus, fungus, or parasite, capable of causing disease in a host.
"Researchers sequenced the emerging pathogene to determine how it causes infection."
"The laboratory identified the bacterium as a pathogene responsible for the outbreak."
"Control measures were introduced to prevent the plant pathogene from spreading to nearby crops."
The regular plural is used when referring to more than one disease-causing organism.
"Several pathogens were detected in the samples."
The name joins the Greek roots for “disease” and “producing,” making a pathogene literally a disease-producing organism.

Where does pathogene come from?
The word combines Greek pathos, meaning “disease” or “suffering,” with the element -gene, meaning “producing” or “born.” It belongs to the same etymological family as pathology, pathogenic, and pathogenesis, all of which concern disease or the production of disease.
How pathogene is actually used
Pathogene is a comparatively uncommon formal or technical term; pathogen is preferred in general and scientific writing. It denotes the causal organism rather than the disease itself.
Easily confused with pathogene
Pathogene is a less common synonym for an organism that causes disease, while pathogen is the standard modern term used across medicine and biology.
