• Zygomycosis: An infectious disease caused by fungus from the orders Mucorales and Entomophthorales which are normally found in the soil and in decaying plant matter. The infection differs from mucormycosis which only involves the order Mucorales. Transmission is usually through the inhalation of spores. It is generally harmless to healthy individuals but can cause infection in patients who are immunocompromised or who have a serious chronic illness such as uncontrolled diabetes. Symptoms and severity can vary considerable depending on the part of the body the infection occurs in - gastrointestinal tract, skin, lungs, central nervous system, eye orbit and the paranasal sinuses.
