Volume 12, Number 3—March 2006
Genus of filamentous, ubiquitous fungi, commonly isolated from soil, plant debris, and indoor air. Aspergillus was first described in 1729 by Pier Antonio Micheli, an Italian priest and biologist who was the first person to attempt the scientific study of fungi. Micheli opposed the idea of "spontaneous generation" by showing that fungal spores grown on a medium would produce the same kind of fungus. The shape of Aspergillus (Figure 1) reminded him of an aspergillum (from the Latin aspergere, "to scatter"), a device used for sprinkling holy water during a liturgical service (Figure 2).
