aspergillin |
A black pigment obtained from various species of Aspergillus; improperly used to designate various antibiotics obtained from Aspergillus. (05 Mar 2000) |
aspergilloma |
1. An infectious granuloma caused by Aspergillus. 2. A variety of bronchopulmonary aspergillosis; a ball-like mass of Aspergillis fumigatus colonizing an existing cavity in the lung. Origin: aspergillus + -oma, tumour (05 Mar 2000) |
aspergillomycosis |
Synonym: aspergillosis. Origin: aspergillus + G. Mykes, fungus, + -osis, condition (05 Mar 2000) |
aspergillosis |
<disease> A fungal (Aspergillus) infection in the tissues marked by inflammatory granulomatous lesions. This infection may affect the lungs, ear canal, skin or the mucous membranes of the eye, nose or urethra. May cause pulmonary aspergillosis in individuals with asthma. More common in the immunocompromised individual (AIDS). Symptoms of disseminated disease include cough, haemoptysis, weight loss, wheezing, fever, chills, haematuria and decreased urine output. Treatment is with amphotericin B. Not transmissible from human to animals or animals to human. (27 Sep 1997) |
aspergillosis precipitin |
<investigation> A test which is used to detect the presence of aspergillus antibodies in the blood. The normal result is read as negative or no antibodies. A strong reaction can indicate pulmonary aspergillosis. Some forms of hypersensitivity pneumonia may also yield a weakly positive test result. (27 Sep 1997) |
aspergillosis, allergic bronchopulmonary |
Aspergillosis of the lung occurring in an individual with long-standing bronchial asthma. It is characterised by pulmonary infiltrates, eosinophilia, elevated serum IgE and immediate type skin reactivity to aspergillus antigen. (12 Dec 1998) |
aspergillum |
1. The brush used in the Roman Catholic church for sprinkling holy water on the people. [Also written aspergillus. 2. <zoology> See Wateringpot shell. Origin: LL. Aspergillum, fr. L. Aspergere. See Asperse, v. T. Source: Websters Dictionary (01 Mar 1998) |
Aspergillus |
<fungus> A genus of common ascomycete fungi found in soil. Industrially important in production of organic acids and a popular fungus for genetic study (especially. A. Niger). (18 Nov 1997) |
Aspergillus acid proteinase |
<enzyme> Included in the group of microbial carboxyl proteinases EC 3.4.23.6; has been sequenced; genbank d87681 Registry number: EC 3.4.23.- Synonym: apfap, aspergillus fumigatus acid proteinase, aspergillus niger acid proteinase, aspergillus awamori acid proteinase (26 Jun 1999) |
aspergillus antigen skin test |
<investigation> An antigen, prepared from aspergillus, is injected into the skin. In 48 to 72 hours the site is read as positive or negative. A positive skin test (inflammation at the test site) indicates prior exposure to aspergillus and therefore a risk for developing aspergillosis. (27 Sep 1997) |
Aspergillus clavatus |
A species isolated from soil and faeces; it yields a carcinogenic mycotoxin known as patulin. (05 Mar 2000) |
aspergillus flavus |
A species of imperfect fungus which grows on peanuts and other plants and produces the carcinogenic substance aflatoxin. It is also used in the production of the antibiotic flavicin. (12 Dec 1998) |
aspergillus fumigatus |
A species of imperfect fungi from which the antibiotic fumigatin is obtained. Its spores may cause respiratory infection in birds and mammals. (12 Dec 1998) |
