Exophiala

Saturated/wet fixtures and biofilm surfaces

Critical — eliminate standing water and biofilm reservoirs

Is Exophiala (Exophiala spp.) dangerous?

Exophiala is classified as a elevated-risk, pathogenic mold with moderate allergenic potential. Primary health concerns include opportunistic infections, allergic responses, biofilm colonization. Significant — can cause systemic phaeohyphomycosis; a particular concern for cystic fibrosis and immunocompromised patients A professional assessment determines the extent and the right response for your property.

Where does Exophiala grow in Gulf Coast homes?

Exophiala commonly appears in drains, faucet aerators, humidifiers, steam rooms. It thrives at 95-100% relative humidity with a water activity of 0.95+ aw, conditions that are common across humid Louisiana and Mississippi Gulf Coast properties.

How do you identify Exophiala?

Black yeast-like colonies that mature to a velvety dematiaceous mat in chronically wet areas Colonies are typically black, olive-black, dark brown with a slimy yeast-like, becoming velvety texture. Damp, biofilm-associated odor Confirmation requires professional sampling and laboratory analysis rather than visual identification alone.

What does remediation of Exophiala involve?

Exophiala typically calls for enhanced containment. Remove colonized porous materials; disinfect plumbing biofilms Critical — eliminate standing water and biofilm reservoirs InspectaMold documents the conditions and provides an independent protocol so the underlying moisture source is corrected, not just the visible growth.
