Resumen:
The city of Bahía Blanca (ArgenVna) presents a high prevalence of asthma and seasonal and perennial allergies. Pollen grains had been cited as the main allergenic components, but no detailed studies of the fungal components transported in the city?s atmosphere existed. The aim of this work is to studythe composition and dynamics of dispersion of particles of fungal origin in the city?s air. The atmosphere was monitored from July 1st to December 31st, 2016 (winter-spring). The aerobiological samples were taken using a Hirst type sampler (Lanzoni) and a cyclonic methodology (μCoriolis sampler). The isolations were made in MEA (malt extract agar). Statistical correlations were donewith the main meteorological parameters. Twenty-four spore types were detected in the atmosphere of the city. The most common were Alternaria and Cladosporium, which were detected regularly throughout the study period, while the remaining spore types recognized presented some kind of seasonality. The µCoriolis sampler enabled the recovery of spores of genera Aspergillus, Penicillium and Rhizopus. Significant correlations were obtained between Pleospora, Leptosphaeria, Torula,Alternaria, Ascospores (Pleospora and Leptosphaeria types) and the meteorological parameters. This study provides an important tool from the health point of view, in order to develop allergy control strategies.
