Research identifies specific bacteria linked to indoor water-damage and mold
Date:6/19/2012

effects of environmental exposures on respiratory health and allergy development in children.

Included homes fell into one of two categories"high mold" or "low mold"based on previously reported environmental relative moldiness index (ERMI), a DNA-based mold level analysis tool developed by the U.S. Environmental Protection Agency (EPA) that combines results of the analysis of 36 different types of mold into one index to describe a home's cumulative mold burden.

The team then compared the ERMI values and types of bacteria found in both high- and low-mold homes in an effort to better understand the environmental sources and home characteristics that influence indoor bacterial contamination.

They found strong correlations between Mycobacterium and visible mold and also between Stenotrophomonas and environmental relative moldiness index.

"Stenotrophomonas maltophiliaan emerging multidrug-resistant global opportunistic pathogenwas isolated from numerous environmental sources. Surprisingly, it was never assessed quantitatively in indoor home environments especially in water damaged homes where this can be a real concern and may cause inhalation exposure risks to occupants. Stenotrophomonas maltophilia is the first bacterial species associated with higher ERMI values in homes," adds Kettleson.
