tox•oid

(ˈtɒk sɔɪd)

Thesaurus
Noun1.toxoid - a bacterial toxin that has been weakened until it is no longer toxic but is strong enough to induce the formation of antibodies and immunity to the specific disease caused by the toxin; "diphtheria toxoid"anatoxinbacterial toxin - any endotoxin or exotoxin formed in or elaborated by bacterial cellsantigen - any substance (as a toxin or enzyme) that stimulates an immune response in the body (especially the production of antibodies)
Translations

toxoid


toxoid,

protein toxintoxin,
poison produced by living organisms. Toxins are classified as either exotoxins or endotoxins. Exotoxins are a diverse group of soluble proteins released into the surrounding tissue by living bacterial cells. Exotoxins have specific reaction sites in the host; e.g.

protein produced by the immune system (see immunity) in response to the presence in the body of antigens: foreign proteins or polysaccharides such as bacteria, bacterial toxins, viruses, or other cells or proteins.

any of a group of antibodies formed in the body as a response to the introduction of poisonous products, or toxins. By introducing small amounts of a specific toxin into the healthy body, it is possible to stimulate the production of antitoxin so that the body's

Toxoid

 

(also anatoxin), a harmless derivative of a toxin that retains its antigenic and immunogenic properties. It is obtained by rendering the toxin harmless with formalin at 37–40°C. A toxoid suitable for immunizing human beings was first obtained in 1923 by the French immunologist G. Ramon. Tetanus and diphtheria toxoids are used as prophylactic measures against these infections. Staphylococcal, botulin, and dysentery toxoids, toxoids produced by the causative agents of gas gangrene and made from the poisons of some poisonous snakes, and other toxoids have been produced and are used for specific prophylaxis and treatment. Toxoids are also used for immunizing horses in order to obtain medicinal antitoxic serums (antitetanus and antidiphtheria).

toxoid

[′täk‚sȯid] (immunology) Detoxified toxin, but with antigenic properties intact; toxoids of tetanus and diphtheria are used for immunization.

toxoid


toxoid

 [tok´soid] a toxin treated by heat or chemical agent to destroy its deleterious properties without destroying its ability to combine with or stimulate the formation of antitoxin.diphtheria toxoid a sterile preparation of formaldehyde-treated products of the growth of Corynebacterium diphtheriae, used as an active immunizing agent, generally in mixtures with tetanus toxoid and pertussis vaccine (DTP) or with tetanus toxoid alone (DT for pediatric use and Td, which contains less diphtheria toxoid, for adult use).tetanus toxoid a sterile preparation of formaldehyde-treated products of the growth of Clostridium tetani, used as an active immunizing agent, either in mixtures with diphtheria toxoid and pertussis vaccine (DTP, DT, Td) or by itself (T).

tox·oid

(tok'soyd), A toxin that has been treated (commonly with formaldehyde) so as to destroy its toxic property but retain its antigenicity, that is, its capability of stimulating the production of antitoxin antibodies and thus of producing an active immunity. For specific toxoids, see entries under vaccine Synonym(s): anatoxin [toxin + G. eidos, resemblance]

toxoid

(tŏk′soid′)n. A substance that has been treated to destroy its toxic properties but retains the capacity to stimulate production of antitoxins, used in immunization.

toxoid

Immunology A bacterial toxin or other antigen treated with formaldehyde to ↓ toxicity while preserving antigenicity; toxoids are used to prepare diphtheria and tetanus vaccines. Cf Freund's adjuvant.

tox·oid

(tok'soyd) A toxin that has been treated (commonly with formaldehyde) so as to destroy its toxic property but retain its antigenicity, i.e., its capability of stimulating the production of antitoxin antibodies and thus of producing an active immunity. [toxin + G. eidos, resemblance]

toxoid

A bacterial toxin that has been chemically changed so as to lose its poisonous properties but retain its ability to stimulate antibody production. Toxoids make excellent vaccines against infections characterized by exotoxin production, such as DIPHTHERIA and TETANUS.

toxoid

a substance produced from a toxin but in which the toxicity is destroyed while the property of inducing immunity to the toxin is retained. Used to immunize against toxigenic infections, for example DIPHTHERIA and TETANUS.

Toxoid

A preparation made from inactivated exotoxin, used in immunization.Mentioned in: Diphtheria

tox·oid

(tok'soyd) Toxin that has been treated (commonly with formaldehyde) to destroy its toxic property but retain its antigenicity, i.e., its capability of stimulating the production of antitoxin antibodies and thus of producing an active immunity. [toxin + G. eidos, resemblance]
