Pathogenesis of indoor fungal diseases.

Mold growth within homes and other buildings has been associated to varying degrees with human health problems. These problems vary from allergenic disease to toxicosis. Case definitions for mold exposure have not been adequately defined to allow for a pathognomonic diagnosis of mold-caused disease following indoor exposure. Some important factors that may contribute to the pathogenesis of indoor mold induced disease include beta (1,3)-D-glucans, outer cell wall fungal hydrophobins, 1,8-dihydroxynaphthalene melanin, fungal volatile organic compounds, mycotoxins, and stachylysin. The information in this contribution was presented as the ISHAM Presidential address as a means to clarify some of the confusing surrounding indoor mold-related health issues.
