| primary cell culture | <cell culture> Of animal cells, the cells taken from a tissue source and their progeny grown in culture before subdivision and transfer to a sub culture. (18 Nov 1997) |
| pure culture | <cell culture, microbiology> A culture containing a single kind of microorganism. (15 Dec 1997) |
| sensitised culture | A live culture of an organism to which a specific antiserum is added; after the mixture is incubated for several minutes (during which the antibody in the serum combines with the organisms), the excess serum is removed by means of centrifugation, washing in physiologic saline solution, and recentrifugation; the sensitised organisms may then be resuspended in physiologic saline solution. (05 Mar 2000) |
| shake culture | A culture made by inoculating a liquefied gelatin or agar medium, distributing the inoculum thoroughly by agitation, and then allowing the medium to solidify in the tube in an upright position. (05 Mar 2000) |
| short rotation intensive culture | Intensive management and harvesting at 2 to 10 year intervals of cycles of specially selected fast- growing hardwood species for the purpose of producing wood as an energy feedstock. (05 Dec 1998) |
| slant culture | A culture made on the slanting surface of a medium which has been solidified in a test tube inclined from the perpendicular so as to give a greater area than that of the lumen of the tube. Synonym: slope 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) |

| 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) |
