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

CINCINNATIBacterial contamination in water-damaged buildings has been identified as a potential cause of health problems, including infection and respiratory conditions like asthma. Which specific bacteria contribute to these problems, however, has been unknownmaking it difficult for public health officials to develop tools to effectively address the underlying source of the problem.

In a new study, a University of Cincinnati (UC) environmental health research team found evidence linking two specific strains of bacteria Stenotrophomonas and Mycobacteriumto indoor mold from water damage. The research is part of the U.S. Department of Housing and Urban Development's investment in research to protect the health of children from hazards in the home.

"If we are going to understand the role of indoor bacteria in human health, we must be able to identify and quantify the relevant bacterial species contributing to the health problems," says Atin Adhikari, PhD, assistant professor of environmental health at the UC College of Medicine and principal investigator of the study.

"The association between bacterial contamination and respiratory health has lagged behind mold studies because it is difficult to determine which species of bacteria are growing in homes and most of the bacterial species are non-culturable and not identified yet," adds Adhikari. "These new data will help us more accurately target and combat the bacteria and to explore synergistic health effects of bacteria and molds growing in water damaged homes."

The UC-based team will report its findings June 18, 2012, at the American Society for Microbiology meeting in San Francisco.

For this study, Adhikari and UC postdoctoral fellow Eric Kettleson, PhD, analyzed samples collected from 42 homes from the Cincinnati Childhood Allergy and Air Pollution Study, a National Institute of Environmental Health Sciences-funded project examining the long-term
