| Abstract: |
| The literature of ca. 10 years ago placed modest emphasis on fungi in relation to bacteria and viruses in indoor air (1,2). Viruses are almost entirely spread by personal contact and no obvious changes in building design or management can alter this (2,3). Many types of bacteria have been reported in indoor air, sometimes in high concentrations. Most of these are normal species associated with skin and nasal-pharyngeal surfaces. There is no direct evidence that the presence of these bacteria in office/residential indoor air contribute to disease (4). However, elevated concentrations of bacteria are normally a sign of poor ventilation (see 5).
Indoor air exposure to Legionell and the endotoxin-containing bacteria is hazardous. However, the management of these bioaerosols in indoor air is well-defined and they rarely pose a health risk (6,7,8). In the last five years, fungi have come to be seen as quantitatively the most important bioaerosols with respect to health in indoor air. This paper will briefly review aspects of microbial problems in buildings. Recent findings regarding the biomedical aspects of fungal contamination of indoor air will be considered with a perspective on the normal mycoflora of indoor air. |
