| 설명 | 세균의 대사에 의해 생산되며 균체 밖으로 내보내는 단백질성 독소이며, 생체에 해롭게 작용한다. 대개는 열민감성이지만 열안정성인 것도 있다. 독소의 합성에 관한 유전자는 염색체성인 것, 파지, 또는 플라스미드에 의한 것이 있다. 독소는 그 작용메커니즘에 따라 신경독소, 창자독소, 세포독소로 분류되며 또한 마비독소, 구토독소, 설사독소, 용혈독소, 백혈구독소 등으로 불린다. 변형독소화에 의해 독성의 상실과 항원성의 유지가 가능하며 백신으로서 이용된다. 외독소의 주된 것은 콜레라독소, 독소원성 대장균의 열민감성 엔테로톡신, 열안정성 엔테로톡신, 장염 비브리오 용혈독, 포도알균 장관독소, 보툴리누스독소, 사슬알균 발적독소, 디프테리아독소, 백일해독소, 파상풍독소, 표피박탈 독소, TSS-1, 대장균 O-157의 배로독소(VT1, VT2)등이 있다. 내독소에 비해 독성이 높다. 외독소를 포르말린 처리로 무독화한 것을 톡소이드라고 하며, 이것은 주사를 해도 안전하며 독소에 대한 능동면역을 부여하는데 이용된다. |

| exotoxin | <protein> Toxin released from gram-positive and gram-negative bacteria as opposed to endotoxins that form part of the cell wall. Examples are cholera, pertussis and diphtheria toxins. Usually specific and highly toxic. (18 Nov 1997) |
|---|---|
| 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) |
| bacterial capsules | An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides. (12 Dec 1998) |
| bacterial cast | A cast in the urine composed of bacteria. (05 Mar 2000) |
| bacterial chemotaxis | <microbiology> The response of bacteria to gradients of attractants or repellents. In a gradient of attractant the probability of deviating from a smooth forward path is reduced if the bacterium is moving up gradient. Since the opposite is true if moving down gradient, the effect is to bias displacement towards the source of attractant. Strictly should perhaps be considered a klinokinesis with adaptation.
