“…Certain genera produce 3-8 different mycotoxins. Cladosporium genus fungi are mostly regarded as phylloplane organisms but certain species produce toxic substances -harmful to birds, horses and, occasionally, to humans [13]. Moreover, it was proved that the dose of mycotoxin required to cause health effect is usually one order of magnitude lower when taken by the airways than by digestive system [17].…”

Abstract:The aim of this research was to evaluate the microbiological indoor air contamination level in chosen facilities of the primary health-care for adults and children. The total numbers of mesophilic bacteria, staphylococci, coli-group bacteria and moulds in both surgery rooms and patients' waiting rooms were determined. Air samples were collected with a MAS 100 impactor and the concentration of microorganisms was estimated by a culture method. The microbiological air contamination level was diverse: the number of mesophilic bacteria ranged from 320 to 560 CFU/m 3 , number of staphylococci -10-305 CFU/m 3 , coli group bacteria -0-15 CFU/m 3 and moulds -15-35 CFU/m 3 . The bacteriological contamination level of the air in examined community health centers was higher than described in the literature for hospitals and exceeded the acceptable values proposed for the surgery objects.

“…Acremonium , Alternaria , Aspergillus , Cladosporium , Fusarium , Paecilomyces , Penicillium , Stachybotrys and Trichoderma are well known mycotoxin producers [48]. Aspergillus flavus and Aspergillus fumigatus can lead to aspergillosis [49], and Microsporium and Trichophyton are agents of dermatophytoses [50]. As the potential implications of the fungal contamination on health have not been studied in Egypt, it should to be reported that exposure to such concentrations and types is a risk factor for resident’s respiratory symptoms.…”

The main objective of the present study was to assess culturable airborne fungal concentrations, and types in different seasons. Two-stage viable impactor samplers were used with malt extract agar medium as the collection media. Culturable airborne fungal concentrations were collected indoors and outdoors of 43 homes in urban and rural environments from November 2008 to October 2009 in Egypt. Fungal concentrations were significantly higher in the rural environment than the urban environment. The median indoor and outdoor total fungal concentrations were 608 and 675 CFU/m3 in the urban environment and 1,932 and 1,872 CFU/m3 in the rural environment, respectively. The greatest concentrations were found in the autumn and spring season. Indoor and outdoor concentrations were significantly correlated (P < 0.001). The highest concentrations were observed in the fungal size range of <8 µm (fine fraction). The indoor/outdoor (I/O) ratios were not statistically different between seasons. Alternaria, Aspergillus, Cladosporium, Penicillium and yeasts were the predominant genera indoors and outdoors, and the abundance of genera varied by season and region. This study is of a potential interest as little reported research on the indoor fungal air quality from Egypt.

“…Fungi -Fungal strains which are proportionally of importance in indoor air samples are comprised of the genera Alternaria, Aspergillus, Cladosporium, and Penicillium [121][122][123][124][125][126]. All fungal strains are able to form spores which are resistant to changing environmental conditions.…”

Bioaerosols such as bacterial and fungal cells and their spores are -along with non-biological particles -part of indoor airborne particulate matter and have been related since a long time to health issues of human beings as well as flora, and fauna. To identify the different risks and to establish exposure thresholds, microbiology of air samples from a series of indoor environments must be characterized, i.e. the different microorganisms (bacteria and fungi) must be identified and quantified. This review discusses the techniques of air sampling and sample analysis. In addition, a literature study has been performed regarding the levels of these microorganisms in various indoor occupational (e.g., schools, offices, hospitals, museums) and dwelling environments. These results will provide a significant scientific basis for indoor air quality control and help in elaborating risk prevention programs for workers and dwellers. This review shall contribute to the knowledge of identification and quantification of airborne microbial constituents in various indoor environments. Combining the indoor microbial load data with data from studies focusing on health effects caused by inhalation of specific airborne microorganisms will allow the evaluation of various risks to which inhabitants are exposed.
