“…Bacteria counts were influenced only by temperature, while aerosol fungi correlated to temperature and relative humidity. These results are in agreement with several studies that reported that the average concentration of airborne microorganisms varied with the presence of people (Van Houdt et al 2009), tourists (Wang et al 2010), indoor activities (Awad et al 2010), and domestic climatic factors temperature and relative humidity (Kakde et al 2001;Sen and Asan 2009;Zhao and Wu 2009;Basilico et al 2007). The airborne concentrations in the Chong Chom border market, Thailand, were significantly higher compared to those in other cities in the world reported (El-Morsy 2006;Van Houdt et al 2009;Aydogdu et al 2010;Liu et al 2010;Di Giulio et al 2010), reflecting the tropical condition, high relative humidity, and temperature year round.…”

Thailand border market is where the local Thais, Cambodians, Laotians, and Burmeses exchange their goods and culture at the border checkpoints. It is considered to be the source of aerial disease transmission especially for foreigners because it is always very crowded with people from all walks of life. Unhealthy air quality makes this area high risk of spread of airborne diseases. This study assessed airborne concentrations of bacteria and fungi in a border market to improve exposure estimates and develop efficient control strategies to reduce health risk. The density and distribution of airborne bacteria and fungi were investigated in the Chong Chom border market in Surin Province, Thailand. Eighteen air sampling sites were taken from outdoors and various work environments including indoor footpaths, wooden handicraft shops, electronic shops, the secondhand clothing shops, and fruit market areas. Exposed Petri plate method and liquid impinger sampler were used for sampling at the breathing zone, 1.5 m above the floor level, during weekend and holiday. Meteorological factors such as relative humidity, temperature, and light intensity were collected by portable data logger. The relative humidity was 67-73%, and temperature 29-33°C, and light varied between 18 and 270 Lux m -2 . Gram-positive and Gram-negative bacteria were found at a mean value of 10 4 CFU m -3 , and airborne fungi of 10 3 CFU m -3 were recorded. The highest concentration of culturable airborne microorganisms was found along the indoor footpath (9.62 9 10 4 CFU m -3 and 750.00 CFU/plate/h for impingement and sedimentation methods, respectively), the fruit market area (7.86 9 10 4 CFU m -3 and 592.42 CFU/plate/h for impingement and sedimentation methods, respectively), and the secondhand clothing shop (4.59 9 10 3 CFU m -3 and 335.42 CFU/plate/h for impingement and sedimentation methods, respectively) for Gram-positive bacteria, Gram-negative bacteria, and fungi, respectively. The lowest concentration of Gram-positive bacteria, Gram-negative bacteria, and fungi was found only at the outdoor area at 1.53 9 10 4 CFU m -3 , 0.93 9 10 4 CFU m -3 and 0.80 9 10 3 CFU m -3 by means of impingement method and 136.67 CFU/plate/h, 69.25 CFU/plate/h, and 62.00 CFU/plate/h by means of sedimentation methods for Gram-positive bacteria, Gram-negative bacteria, and fungi, respectively. The most frequently present airborne bacteria were identified as Bacillus, Corynebacteria, Diplococcus, Micrococcus, Acinetobacter, Alcaligenes, Enterobacter, and spore former rods. Acremonium, Aspergillus, Cladosporium, Penicillium, and Sporotrichum were the most frequently found aerosol fungi genera. The distribution of airborne microorganisms correlated with relative

“…1 Seasonal variations in CFU numbers of Cladosporium, Penicillium, Alternaria and Aspergillus spores constituents of fungal aerosols in both indoor air and outdoor air. Some or all of these genera have been reported as the most common airborne fungi in different indoor and outdoor environments in other studies (Pyrri and Kapsanaki-Gotsi 2007;Abdel-Hameed 2007a, b;Basilico et al 2007;Kim and Kim 2007;El-Morsy 2006;Fang et al 2005;Adhikari et al 2004;Hargreaves et al 2003;Medrela Kuder 2003;Norbäck et al 2000;Katz et al 1999;Li et al 1995). In addition to this, the predominant indoor microfungi reported in this study were consistent with previous indoor air studies carried out by Aydogdu et al 2005;Sarica et al 2002 andYazicioglu et al 2004 from Edirne, Turkey.…”

The purpose of this study was to determine the concentration, in terms of monthly and seasonal distribution and in relation to meteorological factors, of indoor and outdoor microfungi at selected sites in several child day care centers in the city of Edirne, Turkey. Samples were collected at one month intervals over a period of 12 months between January-December 2004, by exposing petri plates containing Peptone Dextrose Agar with Rose-Bengal and Streptomycin medium to the air for 10-15 min. A total of 2,071 microfungal colonies were counted on 192 petri plates. Thirty microfungal genera (Acremonium, Alternaria, Arthrinium, Aspergillus, Bahusakala, Beauveria, Ceuthospora, Chaetomium, Cladosporium, Curvularia, Drechslera, Epicoccum, Eurotium, Fusarium, Mycotypha, Myrotechium, Paecilomyces, Penicillium, Pestalotiopsis, Phoma, Ramichloridium, Rhizopus, Scopulariopsis, Stachybotrys, Stemphylium, Torula, Trichoderma, Trichothecium, Ulocladium, Verticillium) and 75 microfungal species were isolated from the air indoor and outdoor of the day care centers. The dominant microfungal genera were Cladosporium, Penicillium and Alternaria (44.11%, 18.94%, 14.67% of the total respectively), while the genus with the most species richness was Penicillium (26 species). Alternaria, Cladosporium, Penicillium and non-sporulating microfungi were found every month. Cladosporium was the dominant genus in both indoor and outdoor air. Although the predominant genus was the same in both indoor and outdoor air, Cladosporium was followed by Penicillium, Alternaria and Aspergillus genera in indoor air and by Alternaria, Penicillium and Aspergillus genera in outdoor air. While a positive correlation was found between the concentration of monthly outdoor microfungi and monthly average temperature, a negative correlation was found between the concentration of monthly outdoor microfungi and monthly average wind velocity. Also, some relationships were found between the monthly concentrations of the most predominant microfungal genera (Cladosporium, Penicillium and Alternaria) and various meteorological factors.

“…Cladosporium, Alternaria and Penicillium were common across spatial and temporal samples. The genera encountered in this study not only resemble the composition of fungi found in other major city centres in Australia (Garrett et al 1997;Mitakakis & Guest 2001;Rutherford et al 1997) but also other regions that have comparable climates: Santa Fe City, Argentina (Basilico et al 2007), Porto, Portugal (Sousa et al 2008) and Granada, Spain (Sabariego et al 2000). Similarly, previous work has identified increases in spore density and diversity during summer months.…”

A comprehensive survey of airborne fungal spores has been lacking for the Sydney region. This study determined the diversity and abundance of outdoor airborne fungal concentrations in urban Sydney. Monthly air samples were taken from 11 sites in central Sydney, and culturable fungi identified and quantified. The genus Cladosporium was the most frequently isolated spore type, with a frequency of 78% and a mean density of 335 CFU/m 3. The next most frequently encountered genus was Alternaria, occurring in 53% of samples with a mean of 124 CFU/m 3. Other frequently identified fungi, in decreasing occurrence, were: Penicillium, Fusarium, Epicoccum, Phoma, Acremonium and Aureobasidium. Additionally, seasonal and spatial trends of airborne fungi were assessed, with increases in total fungal concentrations experienced in the summer months. The correspondence between a range of key environmental variables and the phenology of airborne fungal propagules was also examined, with temperature, wind speed and proximal greenspace having the largest influence on the aeromycota. If the greenspace comprised of grass, stronger associations with fungal behaviour were observed.
