Pathogenic Molds
Can cause infections in people with weakened immune systems or certain health conditions. Less common but more serious than allergenic types.
Pathogenic molds can cause infections, especially in people with compromised immune systems, chronic illnesses, or those recovering from surgery. Healthy individuals are typically not at risk. Examples include certain Aspergillus and Penicillium species that can infect the lungs, sinuses, or skin.
If you or a family member has a weakened immune system, consult your doctor about mold exposure risks.
Common Pathogenic Species
Aspergillus fumigatus
Gray-green mold. Can cause aspergillosis in immunocompromised individuals.
Penicillium

Various colors. Some species can cause sinus or lung infections.
