| bacterial outer membrane proteins | Proteins isolated from the outer membrane of bacteria. (12 Dec 1998) |
|---|---|
| cell membrane | <cell biology> The structure enveloping a cell, enclosing the cytoplasm and forming a selective permeability barrier. It consists of lipids, proteins and some carbohydrates, the lipids thought to form a bilayer in which integral proteins are embedded to varying degrees. Synonym: plasma membrane. (26 Mar 1998) |
| cell membrane permeability | A quality of cell membranes which permits the passage of solvents and solutes into and out of cells. (12 Dec 1998) |
| coated pits, cell-membrane | Specialised regions of the cell membrane composed of pits coated with a bristle covering made of the protein clathrin. These pits are the entry route for macromolecules bound by cell surface receptors. The pits are then internalised into the cytoplasm to form the coated vesicles. (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) |
| bacterial antagonism | The inhibition of one bacterium by products of another. (05 Mar 2000) |
| bacterial capsule | A layer of slime of variable composition which covers the surface of some bacteria; capsulated cells of pathogenic bacteria are usually more virulent than cells without capsules because the former are more resistant to phagocytic action. (05 Mar 2000) |
