Aspergillus fumigatus is a species of fungus in the genus Aspergillus, and is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. Aspergillus fumigatus , a saprotroph widespread in nature, is typically found in soil and decaying organic matter, such as compost heaps, where it plays an essential ...
Aspergillosis occurs in humans, birds and other animals. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in people with severely compromised immune systems such as those undergoing bone marrow transplantation . [ 7 ]
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.

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 ustus is a microfungus and member of the division Ascomycota. It is commonly found in indoor environments and soil. [ 1 ] Isolated cases of human infection resulting from A. ustus have been described; however the majority of these are nail infections .
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. Gliotoxin is also the only toxin that has been isolated from the sera of patients with invasive aspergillosis.
Aspergillus niger is used in the chemical industry for a variety of applications, while also being a known food contaminant and a possible pathogen to humans. Aspergillus oryzae and A. sojae are used in East Asian cuisine in the production of sake , soy sauce and other fermented food products.
In humans, A. terreus is less commonly encountered as a pathogen than other Aspergillus species, most notably A. fumigatus, A. flavus and A. niger. [ 24 ] [ 26 ] Although less frequently seen in clinical samples, A. terreus displays evidence of amphotericin B resistance which correlates to a high rate of dissemination and an overall poor prognosis.
