Sapronosis

A sapronosis is an infectious disease caused by an organism that is able to live and reproduce in the soil or an other abiotic environment, and infects a living host directly from that environment. One widely-known example of a sapronosis is Legionnaire's disease. Approximately a third of all known disease organisms are sapronoses. Almost all fungal infections are sapronoses, but there are no known sapronotic viruses.
