Aspergillus penicillioides is a species of fungus in the genus Aspergillus, and is among the most xerophilic fungi. [ 1 ] Aspergillus penicillioides is typically found in indoor air, house dust , and on substrates with low water activity , such as dried food, papers affected by foxing , and inorganic objects such as binocular lenses.

In hematologic patients with invasive aspergillosis, the galactomannan test can make the diagnosis in a noninvasive way. Galactomannan is a component of the fungal wall. [ 13 ] False-positive Aspergillus galactomannan tests have been found in patients on intravenous treatment with some antibiotics or fluids containing gluconate or citric acid ...
There are high-quality at-home urine tests available that can be sent to a lab for analysis, LaMandre says. But you should be aware that they are not FDA-approved and can be costly.
Chronic pulmonary aspergillosis is a long-term fungal infection caused by members of the genus Aspergillus—most commonly Aspergillus fumigatus. [8] The term describes several disease presentations with considerable overlap, ranging from an aspergilloma [12] —a clump of Aspergillus mold in the lungs—through to a subacute, invasive form known as chronic necrotizing pulmonary aspergillosis ...
Aspergillus species are highly aerobic and are found in almost all oxygen-rich environments, where they commonly grow as molds on the surface of a substrate, as a result of the high oxygen tension. Commonly, fungi grow on carbon-rich substrates like monosaccharides (such as glucose ) and polysaccharides (such as amylose ).
Infections by other fungi, including Saccharomyces, Aspergillus (as in aspergillemia, also called invasive aspergillosiis) and Cryptococcus, are also called fungemia. It is most commonly seen in immunosuppressed or immunocompromised patients with severe neutropenia, cancer patients, or in patients with intravenous catheters.
Allergic bronchopulmonary aspergillosis; Other names: ABPA, Hinson-Pepys disease. The chest radiograph of an allergic bronchopulmonary aspergillosis patient shown with left-sided perihilar opacity (blue arrow) along with non-homogeneous infiltrates (transient pulmonary infiltrates indicated by red arrows) in all zones of both lung fields.
Gliotoxin is hypothesized to be an important virulence factor in Aspergillus fumigatus. [17] Experiments have demonstrated that gliotoxin is isolated in the highest concentrations from Aspergillus fumigatus in comparison to other Aspergillus species. This species of fungi is the most common cause of aspergillosis in humans.
