Which of the following are considered important indoor allergenic molds?

The correct choice identifies key indoor allergenic molds that are commonly associated with allergic reactions in humans. Penicillium, Aspergillus, Cladosporium, and Alternaria are well-documented as significant contributors to indoor allergies due to their prevalence in various environments.

Penicillium is often found in damp or water-damaged areas and can produce allergens and mycotoxins. Aspergillus is a widespread genus that can also release potent allergens and grow on a variety of building materials. Cladosporium is frequently found in indoor air and can provoke respiratory issues, while Alternaria is known for its high allergenicity and can thrive in both indoor and outdoor environments.

Together, these molds not only contribute to poor indoor air quality but also present serious health risks, particularly for individuals with mold sensitivities or respiratory conditions. Understanding these molds is essential for effective mold inspections and allergy management in indoor settings.
