| specific pathogen-free organisms | Animals or humans raised in the absence of a particular disease-causing virus or other microorganism. Less frequently plants are cultivated pathogen-free. (12 Dec 1998) |
|---|---|
| specific reaction | The phenomena produced by an agent that is identical with or immunologically related to the one that has already caused an alteration in capacity of the tissue to react. (05 Mar 2000) |
| specific serum | A monovalent antiserum, i.e., one obtained by inoculating an animal with one antigen or species or strain of bacteria. (05 Mar 2000) |
| specific soluble polysaccharide | A soluble type-specific polysaccharide produced during active growth of virulent pneumococci composing a large part of the capsule. Synonym: pneumococcal polysaccharide, soluble specific substance, specific soluble polysaccharide, specific soluble sugar. (05 Mar 2000) |
| specific soluble sugar | A soluble type-specific polysaccharide produced during active growth of virulent pneumococci composing a large part of the capsule. Synonym: pneumococcal polysaccharide, soluble specific substance, specific soluble polysaccharide, specific soluble sugar. (05 Mar 2000) |
| specific therapy | Therapy aimed at the cause(s) of a disease process, as opposed to symptomatic therapy. (05 Mar 2000) |
| specific transduction | Transduction in which the bacteriophage strain is able to transfer only some, or only one, of the donor bacterium genes. Synonym: specific transduction. (05 Mar 2000) |
| specific urethritis | An obsolete term for gonorrhoea. (05 Mar 2000) |
| N(2),N(2)-dimethylguanosine-specific tRNA methyltransferase | <enzyme> Responsible for the modification of both mitochondrial and cytoplasmic trnas Registry number: EC 2.1.1.- Synonym: dmg trna methyltransferase (26 Jun 1999) |
| sporulation-specific cell wall hydrolase | <enzyme> From bacillus subtilis; 255-amino acid protein mw 27.146 kD; hydrolyzes both vegetative cell walls and spore peptidoglycan genbank d14666 Registry number: EC 3.- Synonym: cwlc gene product (26 Jun 1999) |
| non-specific | 1. Not due to any single known cause, as to a particular pathogen. 2. Not directed against a particular agent, but rather having a general effect, as non-specific therapy. (18 Nov 1997) |
| non-specific anergy | A reduction of the normal or usual immunologic responses because of unrelated intervening disease. Synonym: non-specific anergy. (05 Mar 2000) |
| non-specific cholinesterase | <enzyme> An enzyme that breaks down acetylcholine tostop its action. (22 May 1997) |
| non-specific protein | A protein substance that elicits a response not mediated by specific antigen-antibody reaction. (05 Mar 2000) |
| non-specific system | <physiology> A physiological term denoting that part of the brainstem reticular formation that plays a central role in the organism's bodily and behavorial alertness. It extends as a diffusely organised neural apparatus through the central region of the brainstem into the subthalamus and the intralaminar nuclei of the thalamus; by its ascending connections it affects the function of the cerebral cortex in the sense of behavioural responsiveness; its descending (reticulospinal) connections transmit its activating influence upon bodily posture and reflex mechanisms (e.g., muscle tonus), in part by way of the gamma motor neurons. See: reticular formation. Synonym: non-specific system. (05 Mar 2000) |
