“…Nevertheless, some studies reported an association between outdoor fungi and incidence of indoor infections (Bouza et al, 2002;Radin et al, 1983;Srinivasan et al 2002). The relationship between outdoor and indoor airborne fungi is much easier to find and has been observed by several researchers (Brenier-Pinchart et al, 2009;Curtis et al, 2005;Dassonville et al, 2008;Falvey & Streifel, 2007;Pini et al, 2004). Air filters like F7-F9 retain around 90 % of the particles, while HEPA filters H13 retain 99.97 % of the particles with more than 0.3 μm.…”

“…All over the world, studies have been carried out in order to evaluate indoor air quality in medical facilities. The fungal airborne values in clinical wards without air filtration system are usually between 50 and 500 CFU x m -3 (Alberti et al, 2001;Brenier-Pinchart et al, 2009;Cooper et al, 2003;Curtis et al, 2005;Dassonville et al, 2008;Falvey & Streifel, 2007;Panagopoulou et al, 2002;Pini et al, 2004;Sautour et al, 2009). In clinical wards with air filtration, airborne fungal values are much lower ranging from 0 to 50 CFU x m -3 .…”

“…Adults spend almost 90% of their time indoors in a variety of enclosed spaces (Klepeis et al, 2001). Among the different spaces, the residential home is of vital importance due to the amount of time spent there, especially for the physically handicapped people such as the elderly and infants who stay at home even up to 95% of their total time (Dassonville et al, 2008;Nasir et al, 2012). Bioaerosol, defined as an airborne particle that is living or originate from living organisms, is one of the most important indoor air contaminants, and they contribute to about 5-34% of indoor air pollution (Srikanth et al, 2008).…”

The present investigation was conducted to assess the culturable concentration and distribution characteristics of airborne bacteria in 31 homes with children aged from 1 to 10 years in Beijing, China. The results showed that the concentration of culturable airborne bacteria in these homes ranged from 47 colony forming units (CFU)/m 3 to 12341 CFU/m 3 , with a mean and a median of 1821 and 877 CFU/m 3 , respectively. A total of 632 bacterial isolates from the air in homes in different regions and different seasons were identified and distributed across 43 genera and 136 species of bacteria. Micrococcus (26.74%), Bacillus (14.56%), Kocuria (12.66%), and Staphylococcus (12.03%) were determined as the most common culturable airborne bacteria, and the dominant bacterial species were Micrococcus luteus (14.56%), Kocuria roseus (8.39%), Bacillus megaterium (4.75%), Staphylococcus cohnii (3.63%), and Micrococcus lylae (3.01%). Data analysis revealed that bacterial concentrations in homes with a male child were significantly higher than those with a female child (**P < 0.01), and a negative correlation was found between bacterial concentration and living area per person in the homes (**P < 0.01). Additionally, the mean bacterial concentration was highest in Spring, followed by Summer and Autumn, and lowest in Winter (**P < 0.01) in homes with child. The results provide an exposure database of airborne bacteria in family homes in Beijing, and suggest that the sex of children and living area per person in homes have a significant influence on the bacterial concentration in the air.

“…Although, the above mentioned genera were identified in the study at hand also, a difference was ascertained in the order of concentrations levels. However, similarly, the types most detected remained the same (Sarıca et al, 2002;Dassonville et al, 2008;Suerdem and Yildirim, 2009).…”

Mosques which are visited by many people every day, for both worship and touristic purposes, play an important role in the spread of infections in society. It is for this reason that research into the fungal concentrations found on the carpets, walls and prayer beads in mosques may prove instrumental in determining potential risks and in protecting the health of visitors. The sampling of fungus content from the carpeting, walls and prayer beads of two different mosques in the province of Istanbul was undertaken with the aim of determining fungi content and levels at two chosen stations in 2015 in the months of January, April, July and October. Samples were taken using dry sterile swabs. The samples brought to the laboratory were cultivated in Peptone-Dextrose Agar in appropriate conditions. The isolated fungi were spot cultivated in Malt Extract Agar (MEA) medium and pure colonies were detected. The preparations extracted from the pure culture of the fungi were examined using a microscope. In the sampling carried out for a duration of four months, 190 colonies were detected. As a result of the study undertaken, 18 different species from 8 genera were isolated. The genera identified were as follows; Alternaria, Aspergillus, Chaetomium, Cladosporium, Penicillium, Scopulariopsis, Trichoderma and Ulocladium. Amongst the genera, the 3 most commonly detected ones were; Aspergillus, 53.2% Penicillium 24.2% and Cladosporium, 14.2%. As a result of the study, the species most isolated, in order, are as follows: Aspergillus fumigatus at 25.8% Aspergillus flavus at 12.7%, Aspergillus parasiticus at 10%, Cladosporium sphaerospermum and Penicillium palitans at 8.4% respectively, Penicillium citreonigrum at 7.4%, Cladosporium cladosporioides at 6.3%, Penicillium citrinum at 5.8%, Chaetomium globosum at 4.2%, Aspergillus niger at 3.2%, Penicillium solitum and Trichoderma longibrachiatum at 1.6% respectively, Alternaria citri, Emericella nidulans and Penicillium chrysogenum at 1.05% respectively and Aspergillus sydowii, Scopulariopsis brevicaulis and Ulocladium alternariae at 0.5% respectively.
