“…Cladosporium and Alternaria contamination are more linked to outdoor sources (Meklin et al, 2007). This may contribute to explain the differences of concentrations related to the sampling season, heating period and aeration of the rooms.…”

Molds and allergens are common indoor biocontaminants. The aims of this study were to assess the concentrations of common molds in indoor air and floor dust and the concentrations of house dust mite, cat and dog allergens in mattress dust in French dwellings, and to assess predictors of these concentrations. A sample of 150 houses in Brittany (western France) was investigated.Airborne Cladosporium and Penicillium were detected in more than 90% of the dwellings, Aspergillus in 46% and Alternaria in only 6% of the housings. Regarding floor dust samples, Cladosporium and Penicillium were detected in 92 and 80% of the housings respectively, Aspergillus in 49% and Alternaria in 14%. House dust mite allergens Der p1 and Der f1 were detected in 90% and 77% of the mattress dust samples respectively and Can f1 and Fel d1 in 37% and 89% of the homes. Airborne and dustborne mold concentrations, although not statistically correlated (except for Aspergillus) shared most of their predictors. Multivariate linear models for mold levels, explaining up to 62% of the variability, showed an influence of the season, of the age of the dwelling, of aeration habits, presence of pets, smoking, signals of dampness, temperature and relative humidity. Allergens in the dust of the mattress were strongly related to the presence of pets and cleaning practices of bedsheets, these factors accounting for 60% of the variability. This study highlights ubiquitous contamination by molds and underlines complex interaction between outdoor and indoor sources and factors.3

“…9 The 36 species in the analysis are based on the 26 group 1 species which we have shown to be associated with homes with water damage and the ten group 2 species which are found in homes independent of water damage. [10][11][12][13][14] Analysis of these molds and mathematical treatment of the data resulted in the creation of the Environmental Relative Moldiness Index (ERMI) scale which describes the mold burden in a home with a single numeric value. 9 The homes in the lowest quartile have the lowest mold burden.…”

The main objective of this study was to evaluate the correlation between the Environmental Relative Moldiness Index (ERMI) values in the Department of Housing and Urban Development American Healthy Homes Survey (AHHS) homes and an alternative analysis frequently used in mold investigations, i.e., the inspector's "walkthrough" assessment of visual or olfactory evidence of mold combined with occupant's answers to a questionnaire about mold odors and moisture. Homes in the highest ERMI quartile were in agreement with visual inspection and/or occupant assessment 48% of the time but failed to detect the mold in 52% of the fourth quartile homes. In about 7% of lowest ERMI quartile homes, the inspection and occupant assessments overestimated the mold problem. The ERMI analysis of dust from homes may be useful in finding hidden mold problems. An additional objective was to compare the ERMI values in inner city east-Baltimore homes, where childhood asthma is common, to the AHHS randomly selected homes.

“…are not among the most commonly isolated fungi from outdoors environment with highest outdoor concentrations in spring and summer [13,15], whereas indoor concentration of these fungi was highest during winter and spring [13]. Other studies have failed to detect any mucorales by PCR from indoor and outdoor air samples [23]. Hence a clear conclusion cannot be reached.…”

Mucormycosis is on the rise especially among patients with immunosuppressive conditions. There seems to be more cases seen at the end of summer and towards early autumn. Several studies have attempted to look at the seasonal variations of fungal pathogens in variou indoor and outdoor settings. Only two reports, both from the Middle East, have addressed the relationship of mucormycosis in human disease with climate conditions. In this paper we review, the relationship of indoor and outdoor fungal particulates to the weather conditions and the reported seasonal variation of human cases.
