Penicillium

Penicillium species are common contaminants on various substances. This organism causes food spoilage, colonizes leather objects and is an indicator organism for dampness indoors. Some species are known to produce mycotoxins. The health of occupants may be adversely affected in an environment that has an amplification of Penicillium.

Penicilliumis characterized by rapidly growing colonies having conidial structures resembling brushes. It commonly produces a strong musty odor. Penicillium marneffei is the only species of the genus that has a yeast-like phase induced by temperature. This can make it more difficult in irradiating it when an infection incurs, but not always impossible.


Commonly found in soil, food, cellulose and grains. It is also found in paint and compost piles. It is also commonly found in carpet, wall paper, and in organic substances inside interior fiberglass duct insulation (NC). Some species can produce mycotoxins.common cause of extrinsic asthma (immediate-type hypersensitivity: type I). Acute symptoms include edema and bronchi spasms, chronic cases may develop pulmonary emphysema. Many patients complain of a suffocating or gasping sensation when suffering from the effects of penicillium toxicity. But unfortunately, these are also the after effects of many other toxigenic molds.

Penicillium is one of the first fungi to grow on water-damaged materials and has been implicated in causing allergic reactions, hypersensitivity pneumonitis, and a variety of severe lung complications. It may cause sarcoidosis, fibrosis, or allergic alveolitis in susceptible individuals, or patients who have been exposed over long periods of time, depending on the strain.
