“…Recently, LOSAPPIO et al [22] observed 20 patients with allergic sensitisation to Olea pollen who presented to an emergency department in Barletta, Italy, for sudden and severe asthmatic symptoms in May 2010 following a thunderstorm. A similar phenomenon has been suggested for moulds [25] after the observation of a possible key role of sensitisation to Alternaria species in thunderstormrelated asthma [21]. To date, among pollens, only grass, Parietaria and olive pollen have been suggested as possible key factors in thunderstorm-related asthma [26].…”

“…It is likely that there is no role for cold or thunderbolts as only patients with allergic sensitisation to pollen and not patients suffering from intrinsic asthma have been involved. In the case of fungal spores, such as Alternaria, the prerequisites for asthma epidemics associated with thunderstorms have been described as follows [20,25]: 1) a sensitised, atopic, asthmatic individual; 2) a sudden, large allergen exposure; 3) a large-scale thunderstorm with cold outflow occurring at a time and location during an allergen season in which large numbers of asthmatics are outdoors; and 4) sudden release of large amounts of respirable allergenic fragments, particularly fungal spores such as Alternaria.…”

“…Although mitosporic fungi and pollen seem to predominate in temperate regions, some aerobiological and epidemiological studies performed in these areas have correlated asthma symptoms with concentrations of basidiospores (Jenkins et al 1980;Delfino et al 1996Delfino et al , 1997Epton et al 1997;Dales et al 2000;Newhouse and Levetin 2004). In addition, some of these studies have also found association of respiratory allergies with meteorological conditions that are suitable for the release of basidiospores, such as high humidity and dew point (Morrow-Brown and Jackson 1985; Davidson et al 1996;Lewis et al 2000;Levetin and Van de Water 2001;Taylor and Jonsson 2004;Nasser and Pulimood 2009).…”

Many known fungal species are grouped among basidiomycetes and ascomycetes. Active mechanisms of spore release into air currents are among the main features of these fungi. Aerobiological studies have described their presence in many regions worldwide. In some areas, fungi have been described as the predominant outdoor airborne biological particulate with much higher concentrations than pollen. Other studies have determined that among the fungal aerospora, the highest concentrations belong to basidiospores and ascospores. Nevertheless, the allergenic potential of spores from basidiomycetes and meiotic forms of ascomycetes has not been studied to the extent of mitosporic fungi and allergens from other sources. The need to further evaluate the role of basidiomycetes and meiotic ascomycetes in allergies is evidenced by the few genera with characterized allergens and limited studies that had demonstrated levels of sensitization similar or higher to that of mitosporic fungi and other allergens. In this review, based on the existing aerobiological, epidemiological, immunological, and molecular biology studies, we provide evidence that the role of basidiomycetes and ascomycetes deserves more attention with respect to their roles as potential aeroallergens.

“…A further genus, Didymella, has been monitored in certain places due to its high abundance in the air and harmful properties. Such spores have been shown to induce allergenic response in sensitised individuals (Harries et al 1985;Nasser and Pulimood 2009). These genera therefore form an important part of the overall bioaerosol load with the implications for ecosystems, crops and human health.…”

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.
