Aureobasidium pullulans

The Aureobasidium pullulans species is ubiquitous. Isolations are most common from plant leaves but have been successful from such diverse environments as humidifiers, house dust, mattress dust, forest soils, sand dunes, peat bogs, estuarine sediments, marine sediments and seawater. In British homes, airborne spores of this species increase sharply in winter months. Interestingly, A. pullulans does not appear to require high levels of nutrients commonly needed by other environmental microbes. This species is also extremely sensitive to heat, and can be found in high humidity areas (e.g. window frames and bathrooms). This fungus is implicated rarely in human infections of the eyes and skin, and A. pullulans infections can be found in blood.
