Mucor Racemosus fungus is a soil fungus and can also be found in horse manure, grains, vegetables, and remains of plants. In the tropic regions the Mucor Racemosus is found at the higher altitudes. Allergy to Mucor Racemosus affects the immune system of an immunologically strong human. People suffering from asthma show higher sensitivity to the Mucor Racemosus. People having a weaker immune system show higher susceptibility towards the Mucor Racemosus allergy. The traditional method involved skin pricking method.
