| streptothrichosis | An infectious exudative dermatitis of cattle, sheep, goats, horses, and other animals (occasionally man) caused by Dermatophilus congolensis; severe (sometimes fatal) dermatophilosis is seen in cattle in the Caribbean, invariable in association with Amblyomma variegatum infestations.

| streptothricin acetyltransferase | <enzyme> Confers resistance to streptothricin in gram-negative bacteria; site of acetylation not specified 4/85 Registry number: EC 2.3.1.- Synonym: acetyl CoA-streptothricin acetyltransferase (26 Jun 1999) |
| streptothricins | <chemical> A group of antibiotic substances produced by streptomyces variants. They are composed of an aminosugar and different polypeptide chains and may have broad spectrum antimicrobial and some antiviral properties. Chemical name: Streptothricin (12 Dec 1998) |
| streptothrix | <biology> A genus of bacilli occurring of the form of long, smooth and apparently branched threads, either straight or twisted. Origin: NL, fr. Gr. Pliant, bent + a hair. Source: Websters Dictionary (01 Mar 1998) |
| streptotrichiasis | An infectious exudative dermatitis of cattle, sheep, goats, horses, and other animals (occasionally man) caused by Dermatophilus congolensis; severe (sometimes fatal) dermatophilosis is seen in cattle in the Caribbean, invariable in association with Amblyomma variegatum infestations.

| streptovaricin | <chemical> A complex of ansamycin antibiotics consisting of streptovaricins a, b, c, d, e, f, g, j, and k of which streptovaricin c is the major component. Pharmacological action: antibiotics, antibiotics, antineoplastic, antiviral agents. (12 Dec 1998) |
| streptovaricins | Antibiotics that block initiation of transcription in prokaryotes. ( Compare:. Rifamycins and rifampicin). (18 Nov 1997) |
| streptozocin | <chemical> An antibiotic that is produced by stretomyces achromogenes. It is used as an antineoplastic agent and to induce diabetes in experimental animals. Pharmacological action: antibiotics, aminoglycoside, antibiotics, antineoplastic. Chemical name: D-Glucose, 2-deoxy-2-(((methylnitrosoamino)carbonyl)amino)- (12 Dec 1998) |
| streptozotocin | Methyl nitroso urea with a 2 substituted glucose, used as an antibiotic (effective against growing gram-positive and gram-negative organisms) and also to induce a form of diabetes in experimental animals (rapidly induces pancreatic B-cell necrosis if given in high-dose). By using multiple low doses in a particular strain of mice, it is possible to produce insulitis followed later by diabetes, a model for juvenile onset diabetes in humans. (18 Nov 1997) |
