“…It is interesting to note that the patterns of the size distributions of airborne fungi are generally very similar to bacterial size distributions but have the peaks, typically, in the size range between 2.1-3.3 and 3.3-4.7 lm. This is typical size distribution pattern for airborne fungi, and similar results have been obtained in highly moldy homes in Poland (Pastuszka et al 2000(Pastuszka et al , 2005. As it can be seen the contribution of fine fungal particles (less than 2.1 lm) is significant in the section of the mechanical treatment and aeration tanks.…”

The aim of this study was to characterize both the viable airborne bacteria and fungi collected in different types of wastewater treatment plants in Poland. Bacterial and fungal aerosols in five different wastewater treatment plants in Poland were studied, including the pioneering antibiotic resistance testing of airborne bacteria. Concentration level was measured using the six-stage Andersen impactor. After incubation, bioaerosol particles captured on nutrient media on Petri dishes were quantitatively evaluated and qualitatively identified. It was found that the concentration levels of both airborne bacteria and fungi ranged from 10 2 to 10 3 colony-forming units/m 3 , in all stages of the wastewater treatment plants. The patterns of size distributions of airborne bacteria and fungi were very similar, showing dominant peaks typically in the size range between 3.3 and 4.7 lm. The majority fraction of small bacterial and fungal particles (less than 4.7 lm) in the studied areas indicates that the bioaerosol is relatively fresh, and mostly of local origin. The Gram-positive cocci and nonsporing Gram-positive rods were the dominating forms in the studied wastewater treatment plants environment. The existing differences in the concentration levels between sampling sites enabled identification of the main bioaerosol sources. The highest concentration of bacterial aerosol appeared in sections, where activated sludge postprocessing and mechanical purifying are conducted. The most frequently occurring species in the sampled bacterial aerosol were Gram-positive cocci and nonsporing Grampositive rods. Multi-antibiotic resistance testing showed that among the isolated airborne bacteria, the most antibiotic-resistant features were present among Bacillus species (especially Bacillus mycoides).

“…Determination of airborne fungal-propagules respirable fraction is important because this parameter assists on estimating the impact of bioaerosols on human health (Pastuszka et al, 2000). Moreover, the amount of outdoor fungal propagules is moderately related with their quantity indoors and vice versa.…”

“…However, infectious diseases caused by inhalation of different fungi depend not only on the number of spores inhaled, but also on the site of deposition in the respiratory system, which is directly related to the aerodynamic diameter of the particle (fungal spore). Particles smaller than 5 μm (the socalled respirable fraction) are able to penetrate into the alveoli and can lead to allergic alveolitis and other serious illnesses (Pastuszka et al, 2000).…”

El objetivo de este estudio fue establecer la variación estacional de propágulos fúngicos en ambientes interiores y exteriores de casas habitación en Mérida, México. Asimismo, este estudio examina la relación entre el número de propágulos fúngicos en ambientes interiores y exteriores con parámetros ambientales como temperatura, humedad y velocidad del viento. El muestreo se realizó durante los periodos de secas (mayo), lluvias (octubre) y frentes fríos (febrero) en el interior y exterior de viviendas. Las medias geométricas de la concentración de propágulos fúngicos interiores y exteriores fueron de 1653 y 1432 UFC/m 3 durante los frentes fríos, de 125 y 92 UFC/m 3 durante el periodo de secas y de 1326 y 1145 UFC/m 3 durante el periodo de lluvias, respectivamente. La fracción respirable se incrementó de 50 a 100%. La composición de géneros fúngicos exhibió una variación estacional: se identificaron 19 géneros durante los tres periodos, entre los que se encuentran principalmente Cladosporium spp., Penicillium spp., Aspergillus spp., Fusarium spp. y Acremonium spp. La concentración de propágulos fúngicos y la heterogeneidad encontrada en Mérida fueron análogas a las detectadas en estudios similares en otras ciudades con clima tropical húmedo. Este estudio concluye que la concentración de propágulos fúngicos y su fracción respirable pueden vincularse con varios factores del medio ambiente, principalmente con la humedad relativa. ABSTRACTThe aim of this study was to establish the seasonal variation of fungal propagules in homes of Mérida, Mexico, and to examine the relation between their concentrations in enclosed and open locations taking into account environmental parameters such as temperature, humidity and wind speed. Samples were taken inside and outside domestic environments during the most characteristic weather seasons in the region: dry season (sampled in May), rainy season (sampled in October), and cold fronts season (sampled in February). The geometric mean of the indoors and outdoors concentration of airborne fungal propagules was 1653 and 1432 CFU/m 3 during the cold fronts period, 125 and 92 CFU/m 3 during the dry period, and 1326 and 1145 CFU/m 3 during the rainy period. The respirable fraction during the three periods sampled was always within a range of 50 to 100%. The composition of fungal genera exhibited a seasonal change, and 19 of these were identified. The main genera found during the three periods were Cladosporium spp., Penicillium spp., Aspergillus spp., Fusarium spp., and Acremonium spp. The fungal aerosol concentrations and diversity found in Mérida, Mexico, were similar to those from other reports of cities with comparable tropical humid climate. This study concludes that the concentration of airborne fungal propagules and its respirable fraction can be related to several meteorological factors, mainly to relative humidity.

“…S. aureus is Gram-positive and has various negative effects on human health. It is one of the most common species in indoor air (Pastuszka et al, 2000;Wan et al, 2011;Cabo Verde et al, 2015). In this work, we applied a range of different filters to capture airborne S. aureus particles: a polypropylene (PP) filter, an activated carbon fiber (ACF) filter, and a metal foam (MF) filter.…”

The application of grapefruit seed extract (GSE) and air ions to filters was investigated with the goal of collecting indoor bioaerosols. GSE exhibits antimicrobial activity because it contains flavonoids such as naringin. Air ions are usually generated by electric ionizers and can inactivate bacteria, viruses, and fungi. In this study, GSE particles were coated onto three different filters: polypropylene (PP), activated carbon fiber (ACF), and metal foam (MF). Ions were supplied to the filter surface using an ionizer. The rate of surface inactivation of Staphylococcus aureus was measured. When only GSE was applied to the filters, the inactivation rate was about 60%; when air ions were applied, the rate was about 70-80%. When both GSE and ions were applied simultaneously, the inactivation rate increased to 80-90%. The physical collection efficiencies of the as-purchased filters were in the following order: PP > ACF > MF. However, when ions were supplied to the filters, the collection efficiencies increased to over 98% for each filter. The inactivation rate of the ACF filter was the highest (92.5%). Therefore, we conclude that the ACF filter is the most efficient of these three filters for inactivating S. aureus.
