PENICILLIUM IN CULTURE
A genus of molds belonging to the Ascomycetes (sac fungi). They form the blue molds that grow on fruits, bread, and cheese. A number of species (P. chrysogenum, P. notatum) are the source of penicillin. Occasionally in humans they produce infections of the external ear, skin, or respiratory passageways. They are common allergens. See: illustration

Penicillium marneffei

A species that may cause systemic infections, esp. in immunocompromised patients. It is found most often in Southeast Asia, where it frequently infects patients with acquired immunodeficiency syndrome.
