Researchers from the University of Cincinnati found out that infants' exposure to spores of a certain group of mold actually increases their likelihood to develop multiple allergies later in life. In particular, they lay the blame to Penicillium/Aspergillus and Alternaria, and that infants exposed to these molds were more likely to develop allergies to mold, pollen, dust mites, pet dander and certain foods as
they grew older.
