| pneumococcal 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) |
|---|---|
| polysaccharide | <biochemistry> Polymers of (arbitrarily) more than about ten monosaccharide residues linked glycosidically in branched or unbranched chains. (18 Nov 1997) |
| polysaccharide deacetylase | <enzyme> Involved in bacteriophage penetration of bacteria Registry number: EC 3.5.1.- (26 Jun 1999) |
| polysaccharide-lyases | <enzyme> A group of carbon-oxygen lyases. These enzymes catalyze the breakage of a carbon-oxygen bond in polysaccharides leading to an unsaturated product and the elimination of an alcohol. Registry number: EC 4.2.2. (12 Dec 1998) |
| polysaccharide pyruvyltransferase | <enzyme> Catalyses the pyruvylation of capsular polysaccharides; phosphoenolpyruvate is donor at the lipid-bound saccharide stage of various bacterial polysaccharides Registry number: EC 2.2.1.- Synonym: capsular polysaccharide pyruvyltransferase (26 Jun 1999) |
| polysaccharide sulfate esters | Sulfate esters of polysaccharides often found in cell walls. (05 Mar 2000) |
| C polysaccharide | <microbiology> Polysaccharide released by pneumococci which contains galactosamine 6 phosphate and phosphoryl choline. C-reactive protein is so called because it will precipitate this polysaccharide through an interaction with the phosphoryl choline. (18 Nov 1997) |
| 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) |
| 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) |
