DESCRIPTION
The definition of indoor microbial communities refers to microbes that are capable of growing indoors. That means that the building is the source of microbes, not the sink. Not all microbes that are detected in a building can actually grow there and constitute part of the building microbiome.

ECOLOGY
The scientific study of interactions
among organisms
and their environment

SLOAN SYMPOSIUMs motto
The interaction between microbial communities
and building materials
needs far greater attention
Corsi et al. Indoor Air 2012; 22: 171-172
What is dead /inactive?
Dead microbes do not affect infrastructures
Dead microbes are not pathogens (but allergens)
What is active?
Dampness promotes active microorganisms
Dampness is associated with SBS
Active microbes produce spores, toxins, MVOCs

CONCLUSIONS
• Look at microbes as organisms, not as sequences
• Know where you sample
• Know why you sample (source/sink?)
• Don’t ignore hidden building structures
• Keep the Gremlings dry!
