| 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) |
| 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) |
| 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 bacterial endocarditis | A type of bacterial endocarditis caused by pyogenic organisms such as haemolytic streptococci or staphylococci. (05 Mar 2000) |
| adhesins, bacterial | Cell-surface components or appendages of bacteria that facilitate adhesion (bacterial adhesion) to other cells or to inanimate surfaces. most fimbriae (fimbriae, bacterial) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. (12 Dec 1998) |
| antibodies, bacterial | Immunoglobulins induced by substances elaborated by bacteria that have an antigenic activity. (12 Dec 1998) |
| antigens, bacterial | Substances elaborated by bacteria that have antigenic activity. (12 Dec 1998) |
| atypical bacterial forms | Microorganisms that have undergone greater changes than normal in morphology, physiology, or cultural characteristics. (12 Dec 1998) |
| bacteria-free stage of bacterial endocarditis | Endocarditis described prior to the antibiotic era and presumably due to spontaneous healing of the bacterial vegetations. (05 Mar 2000) |
| bacterial | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
| bacterial adhesion | Physicochemical property of fimbriated (fimbriae, bacterial) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity. (12 Dec 1998) |
| bacterial allergy | The concept that the atopic kind of type I allergic reactions may be caused by bacterial allergens, the delayed type of skin test, so-called because of its early association with bacterial antigens (e.g., the tuberculin test). (05 Mar 2000) |
