| streptococcus sanguis | A gram-positive organism found in dental plaque, in blood, on heart valves in subacute endocarditis, and infrequently in saliva and throat specimens. L-forms are associated with recurrent aphthous stomatitis. (12 Dec 1998) |
|---|---|
| streptococcus sobrinus | A species of gram-positive, coccoid bacteria isolated from the human tooth surface. Strains have been shown to be cariogenic in experimental animals and may be associated with human dental caries. (12 Dec 1998) |
| streptococcus suis | A species of streptococcus isolated from pigs. It is a pathogen of swine but rarely occurs in humans. (12 Dec 1998) |
| Streptococcus uberis | A species causing mastitis in cattle. (05 Mar 2000) |
| Streptococcus viridans | A name applied not to a distinct species but rather to the group of alpha-haemolytic streptococci as a whole; viridans streptococci have been isolated from the mouth and intestines of humans, the intestines of horses, the milk and faeces of cows, milk and milk products, and the sputum and lungs in cases of primary atypical pneumonia. (05 Mar 2000) |
| Streptococcus zooepidemicus | Former name for Streptococcus equi zooepidemicus. (05 Mar 2000) |
| streptoderma | Pyoderma due to streptococci. (05 Mar 2000) |
| streptodermatitis | Inflammation of the skin caused by the action of streptococci. (05 Mar 2000) |
| streptodornase | <enzyme> Mixture of four DNAases released by streptococci. By digesting DNA released from dead cells the enzyme reduces the viscosity of pus and allows the organism greater motility. (18 Nov 1997) |
| streptodornase and streptokinase | <enzyme> A mixture of the enzymes (streptokinase and streptodornase) produced by haemolytic streptococci. It is used topically on surface lesions and by instillation in closed body cavities to remove clotted blood or fibrinous or purulent accumulations. It is also used as a skin test antigen in evaluating generalised cell-mediated immunodeficiency. Registry number: EC 3.- (12 Dec 1998) |
| streptofuranose | 5-deoxy-3-C-formyl-l-lyxose;an unusual l-pentose that is a component of streptobiosamine, hence of streptomycin. Synonym: streptofuranose. (05 Mar 2000) |
| streptogramin B lyase | <enzyme> An intramolecular lyase similar to EC 5.5.1.1; involved in resistance to etamycin and vernamycin b(alpha) in streptomyces lividans; reaction given in first source Registry number: EC 5.5.1.- (26 Jun 1999) |
| streptokinase | <enzyme> Plasminogen activator released by Streptococcus pyogenes. Occurs in two forms, A and B. (18 Nov 1997) |
| streptokinase-streptodornase | A purified mixture containing streptokinase, streptodornase, and other proteolytic enzymes; used by topical application or by injection into body cavities to remove clotted blood and fibrinous and purulent accumulations of exudate; thus, used in the removal of clots. (05 Mar 2000) |
| streptolydigin | Antibiotic that blocks peptide chain elongation by binding to the polymerase. (18 Nov 1997) |
