Microbial pathogen therapy

Patent Granted A pathogen (Greek: πάθος pathos “suffering, passion” and -γενής -genēs “producer of”) in the oldest and broadest sense is anything that can produce disease. Typically the term is used to mean an infectious agent (colloquially known as a germ) — a microorganism, in the widest sense such as a virus, bacterium, prion, fungus or protozoan, that causes disease in its host. The host may be an animal, a plant, a fungus or even another microorganism.
