TLDR
By DNA analysis, pronounced differences in the relative abundance and seasonal cycles of various groups of fungi in coarse and fine particulate matter are found, with more plant pathogens in the coarse fraction and more human pathogens and allergens in the respirable fine particle fraction.Abstract:
Fungal spores can account for large proportions of air particulate matter, and they may potentially influence the hydrological cycle and climate as nuclei for water droplets and ice crystals in clouds, fog, and precipitation. Moreover, some fungi are major pathogens and allergens. The diversity of airborne fungi is, however, not well-known. By DNA analysis we found pronounced differences in the relative abundance and seasonal cycles of various groups of fungi in coarse and fine particulate matter, with more plant pathogens in the coarse fraction and more human pathogens and allergens in the respirable fine particle fraction (<3 μm). Moreover, the ratio of Basidiomycota to Ascomycota was found to be much higher than previously assumed, which might also apply to the biosphere.read more

TL;DR: A critical analysis of the main ex vivo models of fungal infections is proposed for the evaluation of new antifungal candidates for both topical and systemic use, as opposed to the advantages and disadvantages of the traditional in vivo models employed in preclinical research.

TL;DR: Back-trajectory analyses indicate that the air masses containing ragweed DNA during winter had originated in regions with milder climate and large ragweed populations (Southern France, Carpathian Basin), which can be explained by atmospheric long-range transport.

TL;DR: The spontaneous decay of DNA is likely to be a major factor in mutagenesis, carcinogenesis and ageing, and also sets limits for the recovery of DNA fragments from fossils.
