“…The levels of airborne bacteria and fungi in June and September were much higher than those collected in January and March, thereby indicating the seasonal variations in airborne bacteria and fungi emission. Relative humidity and temperature are the significant environmental parameters that affected the release and dispersal of bioaerosols, especially for those generated from the process units installed indoors (O'Gorman and Fuller 2008). Temperature and water availability would affect the release of some active bacterial and fungal spores.…”

The emission of the airborne bacteria and fungi from an indoor wastewater treatment station adopting an integrated oxidation ditch with a vertical circle was investigated. Microbial samples were collected by the six-stage viable Andersen cascade impactor, and the samples were collected in triplicate in each sampling site per season. Culture-based method was applied to determine the concentrations of the airborne bacteria and fungi, while the cloning/ sequencing method was used to characterize the genetic structure and community diversity of airborne bacteria. The highest concentrations of airborne bacteria (4155 ± 550 CFU/m 3 ) and fungi (883 ± 150 CFU/m 3 ) were obtained in June (summer). The lowest concentration of bacteria (1458 ± 434 CFU/m 3 ) was determined in January (winter), and the lowest concentration of fungi (169 ± 40 CFU/m 3 ) was found in March (spring), respectively. The particle size distribution analysis showed that most culturable bacteria obtained in all the sampling sites were in the particle size range of 1.1-4.7 lm. Most culturable fungi had particle sizes in the range 1.1-3.3 lm. Microbial population analysis showed that Bacillus sp., Acinetobacter sp., and Lysinibacillus were the main groups obtained in S1.Enterobacter was the dominant group in sampling site S2. Both the concentrations and particle size distribution of the bioaerosols in the enclosed space presented a seasonal and site-related variation. Concentration and richness of microorganisms in bioaerosols in June were higher than in September and January. The particle size distribution varied between the sampling sites, and proportion of large particles was higher in S2 than in S1 because of the settlement of large particles. Pathogenic species, such as Acinetobacter lwoffii, Staphylococcus saprophyticus, and Enterobacter sp., were isolated from the bioaerosols, which could pose serious latent danger to sewage workers' health.

“…Temperature and water availability would affect the release of some active bacterial and fungal spores. In environments with high humidity, fungal spores released into the air could cause infections or allergic reactions in humans (O'Gorman and Fuller 2008). High temperature and relative humidity favor microbiological growth.…”

“…At a similar period of time, collections of Cladosporium and basidiospores were made in Dublin with the results analysed much later, in 1990 (Stephen et al 1990). A more recent study has focused on the use of culture techniques for sampling ambient fungal spore concentrations in Galway (O'Gorman and Fuller 2008). Since then, no further aerobiological surveys have been carried out in the Republic of Ireland.…”

Atmospheric concentrations of Alternaria, Cladosporium, Ganoderma and Didymella spores monitored in Cork (Ireland) and Worcester (England) during the summer of 2010

This study represents the first international intercomparison of fungal spore observations since 1990, focusing on atmospheric concentrations of Alternaria, Cladosporium, Ganoderma and Didymella spores. The campaigns were performed at sites located in Cork (Ireland) and Worcester (England) during summer 2010. Observations were made using Hirsttype volumetric spore traps and corresponding optical identification at the genus level by microscope. The measurements at both sites (including meteorological parameters) were compared and contrasted. The relationships between the fungal spore concentrations with selected meteorological parameters were investigated using statistical methods and multivariate regression trees (MRT). The results showed high correlations between the two sites with respect to daily variations. Statistically significant higher spore concentrations for Alternaria, Cladosporium and Ganoderma were monitored at the Worcester site. This result was most likely due to the differences in precipitation and local fungal spore sources at the two sites. Alternaria and Cladosporium reached their maxima a month earlier in Cork than in Worcester, and Didymella with Ganoderma peaked simultaneously with similar diurnal trends found for all the investigated spore types. MRT analysis helped to determine threshold values of the meteorological parameters that exerted most influence on the presence of spores: they were found to vary at the two sites. Our results suggest that the aeromycological profile is quite uniform over the British Isles, but a description of bioaerosols with respect to overall load and daily concentration can be quite diverse although the geographical difference between sites is relatively small. These variations in the concentrations therefore need to be explored at the national level.

In this study the sampling of microfungus content from the carpeting, walls and Holy Qurans of two different mosques in the province of Istanbul was undertaken and in order to determine quantities. Samples were taken in 2015 during the months of January, April, July and October. The samples were taken with non-agar based sterile swabs and were then taken to the laboratory. Throughout the duration of the study, 17 species belonging to 9 genera were isolated and a total of 193 colonies were examined. Throughout the study the most commonly isolated microfungus genus was Aspergillus at 52.9%. This genus was followed by Penicillium at 26.5%, Cladosporium at 7.8%, Alternaria at 4.7%, Chaetomium at 2.6%, Trichoderma at 3.2%, Mucor at 1.1% and Eurotium and Rhizopus 0.6%. Throughout the duration of the study the most isolated species of microfungus was Aspergillus fumigatus at 25.9%. This species was followed by Aspergillus flavus at 9.8%, Penicillium palitans at 9.3%, Aspergillus niger at 8.3%, Penicillium citreonigrum at 7.8%, Penicillium solitum at 6.3%, Aspergillus sydowii at 5.2%, Alternaria alternata and Cladosporium sphaerospermum at 4.7%, Aspergillus parasiticus at 3.7%, Trichoderma longibrachiatum at 3.2%, Penicillium citrinum and Cladosporium cladosporioides at 3.1%, Chaetomium globosum at 2.6%, Mucor sp. at 1.1%, and finally Eurotium herbariorum and Rhizopus stolonifer at 0.6%.
