| 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) |

| allergic bronchopulmonary aspergillosis | <radiology> ABPA: Aspergillus fumigatus hypersensitivity, mucoid impaction of bronchi distal to lobar bronchus, mucus plugs contain fungi, eosinophils, XR: Y-shaped density (mucus plug wedged in bronchi) (12 Dec 1998) |

| 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, 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) |
| bronchopneumonic aspergillosis | An inflammatory and destructive disease of the bronchi and lungs due to the presence and growth of Aspergillus fumigatus. There are four varieties: 1) a bronchial infection with allergic manifestations, in which the fungus grows in the mucus (evoked by the inflammation), which may be expectorated as yellow bronchial casts and may cause intermittent bronchial obstruction, with transient pulmonary shadows seen radiographically; asthma is often present, and bronchial wall destruction may eventually result in a proximal form of bronchiectasis; 2) aspergilloma; 3) an infection with pulmonary necrosis as a pneumonic involvement of the lung in debilitated subjects; 4) disseminated aspergillosis. Synonym: bronchopneumonic aspergillosis, pulmonary aspergillosis. Disseminated aspergillosis, a variety of bronchopulmonary aspergillosis, characterised by a generalised infection of the lung with Aspergillus occurring usually in subjects with defective immune response. Invasive aspergillosis, so-called because of the peculiar predilection of Aspergillus fumigatus to invade blood vessels and cause tissue infarction; it is second only to candidiasis as a cause of opportunistic fungal infection in patients whose immune mechanisms have been suppressed by chemotherapy.

| gel diffusion precipitin tests | Precipitin test's in which the immune precipitate forms in a gel medium (usually agar) into which one or both reactants have diffused; generally classified in two types, in one dimension, and in two dimensions. Synonym: gel diffusion reactions. (05 Mar 2000) |
| gel diffusion precipitin tests in one dimension | Precipitin test's in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single (gel) diffusion in one dimension). (05 Mar 2000) |
| gel diffusion precipitin tests in two dimensions | Precipitin test's made in a layer of agar that permits radial diffusion, in both of the horizontal dimensions, of one or both reactants. Double (gel) diffusion in two dimensions (Ouchterlony test, technique, or method) incorporates antigen and antibody solutions placed in separate wells in a sheet of plain agar, permitting radial diffusion of both reactants; this method is widely used to determine antigenic relationships; the bands of precipitate that form where the reactants meet in optimal concentration are of three patterns, referred to as reaction of identity, reaction of partial identity (cross-reaction), and reaction of nonidentity. (05 Mar 2000) |
| ring precipitin test | A precipitin test in which antigen solution is carefully layered over antibody solution in a tube; as diffusion proceeds, a disk of precipitate forms where the antibody ratio is optimal. Synonym: ring test. (05 Mar 2000) |
| precipitin | <protein> Any antibody that forms a precipitating complex (a precipitin line) with an appropriate multivalent antigen. The term is now outmoded. (18 Nov 1997) |
| precipitin reaction | See: precipitin, precipitin test. (05 Mar 2000) |
| precipitin test | An in vitro test in which antigen is in soluble form and precipitates when it combines with added specific antibody in the presence of an electrolyte. See: gel diffusion precipitin tests, ring precipitin test. Synonym: precipitation test. (05 Mar 2000) |
| precipitin tests | Serologic tests in which a positive reaction manifested by visible precipitation occurs when a soluble antigen reacts with its antibody. (12 Dec 1998) |
