| bacterial typing techniques | Procedures for identifying types and strains of bacteria. The most frequently employed typing systems are bacteriophage typing and serotyping as well as bacteriocin typing and biotyping. (12 Dec 1998) |
|---|---|
| bacteriophage typing | A technique of bacterial typing which differentiates between bacteria or strains of bacteria by their susceptibility to one or more bacteriophages. (12 Dec 1998) |
| phage typing | <microbiology> Bacteria may be typed by their susceptibility to a range of bacteriophages though confusion may arise if the bacteria carry plasmids encoding restriction endonucleases. (18 Nov 1997) |
| mycological typing techniques | Procedures for identifying types and strains of fungi. (12 Dec 1998) |
| HLA typing | <immunology> Tests done in order to determine if a patient has antibodies against a potential donor's HLA antigens. The presence of antibodies means that a particular graft will be rapidly rejected. (05 Mar 2000) |
| DNA typing | <molecular biology> See restriction fragment length polymorphism. (18 Nov 1997) |
| tissue typing | <procedure> The process of determining the allelic types of the antigens of the major histocompatibility complex (MHC) that determine whether a tissue graft will be accepted or rejected. at present carried out either by use of polyclonal or monoclonal antibodies against MHC antigens or less usually by tests of MHC restricted cell function or skin grafting (the latter not in humans). (18 Nov 1997) |
| typing | Classification according to type. Origin: see type Bacteriophage typing, a microbiological procedure, of epidemiological importance, for distinguishing types within a seemingly homogeneous bacterial species or strain by the use of type-specific bacteriophage. HLA typing, tests done in order to determine if a patient has antibodies against a potential donor's HLA antigens. The presence of antibodies means that a particular graft will be rapidly rejected. Also used to establish paternity and in forensic medicine. (05 Mar 2000) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
| absorption cell | A small glass chamber with parallel sides, in which absorption spectra of solutions can be obtained. (05 Mar 2000) |
| acid cell | One of the cell's of the gastric glands; it lies upon the basement membrane, covered by the chief cell's, and secretes hydrochloric acid that reaches the lumen of the gland through fine intracellular and intercellular canals (canaliculi). Synonym: acid cell, oxyntic cell. (05 Mar 2000) |
| acidophil cell | A cell whose cytoplasm or its granules stain with acid dyes. (05 Mar 2000) |
| acinar cell | Any secreting cell lining an acinus, especially applied to the cell's of the pancreas that furnish pancreatic juice and enzymes to distinguish them from the cell's of ducts and the islets of Langerhans. Synonym: acinous cell. (05 Mar 2000) |
| acinar cell tumour | A solid and cystic tumour of the pancreas, occurring in young women; tumour cells contain zymogen granules. (05 Mar 2000) |
| acinic cell adenocarcinoma | <tumour> An adenocarcinoma arising from secreting cells of a racemose gland, particularly the salivary glands. Synonym: acinar carcinoma, acinic cell carcinoma, acinose carcinoma, acinous carcinoma. (05 Mar 2000) |
