| streptococcal toxins | Group of haemolytic exotoxins released by Streptococci. _ haemolysin: 26-39 Kd (four types), forms ring like structures in membranes (see Streptolysin O). Lipid target unclear. _ haemolysin: a hot cold haemolysin with sphingomyelinase C activity. _ haemolysin: complex of two proteins (29 and 26 kD) that act synergistically, rabbit erythrocytes particularly sensitive. _ toxin: heat stable peptide (5 kD) with high proportion of hydrophobic amino acids. Seems to act in a detergent like manner (c.f. Subtilysin), but may form hydrophilic transmembrane pores by cooperative interaction with other _ toxin molecules. Leucocidin (Panton Valentine leucocidin): two components f (fast migration on CM cellulose column: 32 kD) and s (slow: 38 kD). Mode of action contentious. See: Streptococcus, streptolysins O and S, erythrogenic toxin. (18 Nov 1997) |

| bacterial toxins | Toxic substances formed in or elaborated by bacteria; they are usually proteins with high molecular weight and antigenicity; some are used as antibiotics and some to skin test for the presence of or susceptibility to certain diseases. (12 Dec 1998) |
|---|---|
| botulinum toxins | <chemical> Toxins produced by clostridium botulinum. There are at least seven different substances, most being proteins. They have neuro-, entero-, and haemotoxic properties, are immunogenic, and include the most potent poisons known. The most commonly used apparently blocks release of acetylcholine at cholinergic synapses. Pharmacological action: anti-dyskinesia agents. (12 Dec 1998) |
| marine toxins | Toxic or poisonous substances elaborated by marine flora or fauna. They include also specific, characterised poisons or toxins for which there is no more specific heading, like those from poisonous fishes. Clupeotoxin, pahutoxin, prymnesin, scombrotoxin go here. (12 Dec 1998) |
| pertussis toxins | <chemical> Any of various biologically active proteins or toxins elaborated by bordetella pertussis that cause the symptoms of whooping cough. Some activate pancreatic islets, others inhibit the adenylate cyclase cascade and some cause lymphocytosis. Chemical name: Toxins, pertussis (12 Dec 1998) |
| toxins | Poisons produced by certain animals, plants, or bacteria. (12 Dec 1998) |
| lyngbya toxins | Toxins isolated from any species of the seaweed lyngbya or similar chemicals from other sources, including mollusks and micro-organisms. These have been found to be potent tumour promoters. (12 Dec 1998) |
| acute post-streptococcal glomerulonephritis | <nephrology> A disease of the kidneys that results in inflammation of the glomerulus (the portion of the kidney that filters the blood). Conditions which may cause glomerulonephritis include post-streptococcal disease (strep throat), lupus, syphilis, bacterial endocarditis, membranoproliferative glomerulonephritis, sepsis, vasculitis, Goodpasture's syndrome, typhoid fever, Henoch-Schonlein purpura, hepatitis or a viral infection (for example mumps, measles, mononucleosis). (27 Sep 1997) |
| group A streptococcal necrotizing fasciitis | A complication of infection with GAS (group A streptococci) in which the bacteria attacks and destroys muscle tissue. According to the CDC, 5-10% of people with severe GAS infection develop necrotizing fasciitis. Though the infection can be treated with antibiotics, the fatality rate is close to 30%. This complication often develops as a wound infection after surgery or injury. (05 Mar 2000) |
| streptococcal | Relating to or caused by any organism of the genus Streptococcus. (05 Mar 2000) |
| streptococcal fibrinolysin | <enzyme> Plasminogen activator released by Streptococcus pyogenes. Occurs in two forms, A and B. (18 Nov 1997) |
| streptococcal infections | Infections with bacteria of the genus streptococcus. (12 Dec 1998) |
| streptococcal lymphadenitis | A contagious bacterial disease of pigs caused by a group E streptococcus and characterised by the formation of abscesses in the cervical and/or cephalic lymph nodes. (05 Mar 2000) |
| streptococcal nuclease | <enzyme> From streptococcus haemolyticus; degrades RNA and DNA producing oligonucleotides terminating in 5'-phosphate Registry number: EC 3.1.30.- (26 Jun 1999) |
| streptococcal pneumonia | Pneumonia due to Streptococcus pyogenes. (05 Mar 2000) |
