What is mold?
There are thousands of types of molds and yeasts in
the fungus family. Yeasts are single cells that divide to
form clusters. Molds are made of many cells that grow
as branching threads called hyphae. Although both can
probably cause allergic reactions, only a small number
of molds are widely recognized offenders.
The seeds or reproductive pieces of fungi are called
spores. Spores differ in size, shape, and color among
types of mold. Each spore that germinates can give
rise to new mold growth, which in turn can produce
millions of spores.
What is mold allergy?
When inhaled, tiny fungal spores, or sometimes pieces
of fungi, may cause allergic rhinitis. Because they are
so small, mold spores also can reach the lungs.
In a small number of people, symptoms of mold allergy
may be brought on or worsened by eating certain foods
such as cheeses processed with fungi. Occasionally,
mushrooms, dried fruits, and foods containing yeast,
soy sauce, or vinegar will produce allergy symptoms.
