Aspergillus and Malassezia spp: The fungal
spores are between 2-20 μm in diameter and
particles less than 5 μm in diameter; these descend
into the lower respiratory airways and lead to
allergic asthma symptoms. Therefore, fungal
spores are the main allergen in asthmatic patients.
Storm asthma was correlated to a two-fold increase
in the number of fungal spores in the air (Fairs et al.,2010; Agarwal et al., 2009).
