Acremonium

Acremonium is a fungal genus formerly known as Cephalosporium. It is a widespread mold currently believed to contain about 100 species. Species of this mold exist as saprophytes in a wide variety of habitats or as plant and animal pathogens.

Health Significance

Some species of Acremonium have been reported to be allergenic while some are known to produce mycotoxins. In medical literature, Acremonium has been reported as the cause of pulmonary infections and infections of the cornea and nails in individuals with weak immune systems. There are three main species of Acremonium associated with human infections: Acremonium falciforme, Acremonium kiliense, and Acremonium recifei. The 3 species are biosafety level 2 fungi.

Occurrence of Acremonium in indoor environment

In indoor environment, Acremonium species are primarily isolated from acoustic and thermal fibreglass insulation used in heating ventilation and air conditioning systems, cooling coils, drain pans, windowsills, and water from humidifiers. Also found on carpet and mattress dust, damp or wet walls (especially in basements), gypsum board and wallpaper. The most common species in indoor environment are Acremonium strictum and Acremonium charticola.
