| smear culture | A culture obtained by spreading material presumed to be infected on the surface of a solidified medium. (05 Mar 2000) |
| sputum culture | The incubation of expectorated material for the purpose of identifying a bacterial contaminant. Sputum cultures can assist the physician in appropriate antibiotic choice for the treatment of pneumonia or bronchitis. (27 Sep 1997) |
| stab culture | A culture produced by inserting an inoculating needle with inoculum down the centre of a solid medium contained in a test tube. Synonym: needle culture. (05 Mar 2000) |
| nasopharyngeal culture | <microbiology> A sample of nasopharyngeal secretions are obtained via a swab stick (Q-tip-like) and sent to the lab for bacterial or viral culture. This test is used to identify an organism or virus which is responsible for respiratory disease and can also guide the selection of an effective antibiotic agent. (27 Sep 1997) |
| nasopharyngeal viral culture | <microbiology> A collection of nasopharyngeal secretions for the purpose of incubating a virus for identification. (27 Sep 1997) |
| needle culture | A culture produced by inserting an inoculating needle with inoculum down the centre of a solid medium contained in a test tube. Synonym: needle culture. (05 Mar 2000) |
| neotype culture | A strain accepted by international agreement to replace a type strain which is no longer in existence or to serve as the type strain if a type strain was not designated and if no strain exists which can be designated as the type. Synonym: neotype culture. (05 Mar 2000) |
| stock culture | A culture of a microorganism maintained solely for the purpose of keeping the microorganism in a viable condition by subculture, as necessary, into fresh medium. (05 Mar 2000) |
| stool culture | A test used to identify pathogenic organisms in the stools that may be responsible for gastroenteritis. Often performed in cases of unexplained diarrhoea. May indicate bacterial, viral or parasitic disease. Cultures are also helpful in assisting the selection an appropriate antibiotic agent. See: Traveler's Diarrhoea. (27 Sep 1997) |
| streak culture | A culture produced by lightly stroking an inoculating needle or loop with inoculum over the surface of a solid medium. (05 Mar 2000) |
| diffusion chambers, culture | Devices used in a technique by which cells or tissues are grown in vitro or, by implantation, in vivo within chambers permeable to diffusion of solutes across the chamber walls. The chambers are used for studies of drug effects, osmotic responses, cytogenic and immunologic phenomena, metabolism, etc., and include tissue cages. (12 Dec 1998) |
| discontinuous culture | A technique for production of microbes or microbial products in which the organisms are grown in a closed system until one nutrient factor becomes rate-limiting. (05 Mar 2000) |
| Dorset's culture egg medium | A medium for cultivating Mycobacterium tuberculosis; it consists of the whites and yolks of four fresh eggs and a solution of sodium chloride. (05 Mar 2000) |
