Forintek Canada Corp. created a Building Microbiology Database in 2002 and formed an expert team including an Associate Professor from the University of British Columbia's School of Environmental and Occupational Hygiene. The Database largely contains information from peer-reviewed journals in which there is a link between building materials, microorganisms and health. In response to three questions compiled by the American Forest and Paper Association and Forintek Canada Corp. the Database was searched for information. These questions concerned molds and bluestain fungi growing on wood. The Database does not contain much information on the basic biology of these organisms therefore additional literature was obtained to respond to the questions. The answers, with a scientific rationale for each, are given in this report.
