Coloured scanning electron micrograph (SEM) of the common indoor allergenic mould Aureobasidium pullulans. Seen here is fungal hyphae stage producing yeast buds. This species also grows as a yeast form under certain environmental conditions. Aureobasidium pullulans is also known as Pullularia pullalans . Aureobasidium is a common indoor mould that grows in damp places. It occurs indoors in very damp areas and in free standing water, such as condensate pans, or following a flood. Spores only become airborne through mechanical disruption of contaminated materials or aspiration of contaminated water. It is not a primary human pathogen nor is it recognized as a producer of significant mycotoxins. High airborne levels of this fungus have been associated with allergic complaints probably due to respiratory irritation mediated by cell-wall components (e.g. beta glucans, glycoproteins)Magnification: x800 when shortest axis printed at 25 | |
