| smooth strain | <microbiology> Bacterial strains that have altered outer cell wall carbohydrate chains causing colonies on agar to change their appearance from smooth to dull. In Streptococci the smooth strains are virulent whereas the rough strains are not. This is partly because the rough strains are much more readily phagocytosed. (17 Dec 1997) |
| neotype strain | 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 strain | A bacterial or other microbial strain that has been maintained under laboratory conditions as representative of its type. (05 Mar 2000) |
| strain | A tearing injury to muscle. Usually causes some degree of bleeding within the muscle tissue (haematoma). (27 Sep 1997) |
| strain birefringence | <chemistry> Optical property of a material in which the refractive index is different for light polarized in one plane compared to the orthogonal plane. May arise from molecular organisation of the material (form birefringence.), alignment of molecules due to tension (stress birefringence.) or alignment of rod like particles in flow (flow birefringence). With crossed Nicoll prisms a birefringent material appears bright against a dark background. (19 Jan 1998) |
| strain development | Improving the genetics of an organism so that it carries out a biotechnological process more effectively. (14 Nov 1997) |
| strain fracture | The tearing off, by a sudden force, of a piece of bone attached to a tendon, ligament, or capsule; the force may be exogenous or endogenous. (05 Mar 2000) |
| strain gauge | A device, employing the Wheatstone bridge principle, used for accurate measurement of forces such as strain, stress, or pressure. (05 Mar 2000) |
| stress-strain curve | A curve showing the ratio of deformation to load during the testing of a material in tension. (05 Mar 2000) |
| inbred strain | Any strain of animal or plant obtained by a breeding strategy that tends to lead to homozygosity. Such breeding strategies include brother sister mating and back crossing of offspring with parents. See: congenic. (18 Nov 1997) |
| quiet hip disease | perthes disease |
| isogenic strain | A strain of animals inbred for many generations and with high probability homozygous for certain specified genes. (05 Mar 2000) |
| osteoarthritis, hip | Noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. It is characterised by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. A dominant symptom is pain on weight-bearing or motion. (12 Dec 1998) |
| triceps muscle of hip | <anatomy> The obturator internus and superior and inferior gemellus muscles considered as one muscle, inserting via a single tendon into the greater trochanter of the femur. Synonym: musculus triceps coxae, triceps muscle of hip. (05 Mar 2000) |
