“…Alternaria and Cladosporium have been identified as the most abundant and frequent airborne allergens in several cities in the Iberian Peninsula (Infante et al 1988;González Minero et al 1993;Fernández González et al 1993;Munuera Giner and Carrión García 1995;Herrero et al 1996) and their allergenic capacity has been reported by numerous authors (Budd 1986;Vijay et al 1991;Srivastava and Wadhwani 1992;Caretta 1992;Martínez et al 1994). Since the sporulation process and spore dispersion of fungi are greatly dependent on the climatic conditions in each area, many authors have correlated meteorological parameters with the presence and prevalence of airborne spores in the atmospheres of climatically different locations.…”

A study was made of the link between climatic factors and the daily content of certain fungal spores in the atmosphere of the city of Granada in 1994. Sampling was carried out with a Burkard 7-day-recording spore trap. The spores analysed corresponded to the taxa Alternaria, Ustilago and Cladosporium, with two morphologically different spore types in the latter genus, cladosporioides and herbarum. These spores were selected both for their allergenic capacity and for the high level of their presence in the atmosphere, particularly during the spring and autumn. The spores of Cladosporium were the most abundant (93.82% of the total spores identified). The Spearman correlation coefficients between the spore concentrations studied and the meteorological parameters show different indices depending on the taxon being analysed. Alternaria and Cladosporium are significantly correlated with temperature and hours of sunlight, while Ustilago shows positive correlation indices with relative humidity and negative indices with wind speed.

“…Together with Cladosporium, they are also considered one of the most important aeroallergens (Budd 1986). They require certain meteorological conditions for their development, and in different studies temperature and humidity have been shown to be factors conditioning their presence in the air.…”

In this study, we have analyzed the presence of conidia belonging to different species of the genus Alternaria in the atmosphere of the city of Cordoba, using a Hirst sampler. The results show that spores of this genus are present all year, with a clear seasonal pattern which shows two peaks, one in spring and the other in fall. A total of 26,822 conidia/m3 have been sampled, which implies a daily mean of 74.3 conidia/m3. Statistical analyses comparing the data with meteorological parameters show a positive correlation with maximum, minimum and mean temperatures, and a negative correlation with rain. Nevertheless, meteorological parameters seem to affect the number of conidia differently according to the season of the year. Regression analyses carried out in order to obtain a predictive pattern show that the best fit is between the 7-day running mean of the number of conidia and a week's accumulated mean temperature.
