An altered form of a toxin, possessing little or no toxic power.
A denatured toxin. It retains the ability to stimulate the formation of antitoxin in an animal's body.
A toxin modified so that it is no longer toxic but is still able to induce antibody formation.
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"
a bacterial toxin that is treated to make it harmless but still can induce immunity to the disease
a denatured (nonpathogenic) toxin which stimulates an immune response against the toxin but not necessarily the organism as a whole
an inactivated toxin, the harmful substance produced by a microbe
a toxin which has been rendered non-toxic (usually by treatment with formalin) but which remains antigenic
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 antibody (antitoxin) e.g. Clostridial vaccines.
Inactivated or killed toxin (such as diphtheria or tetanus) used in vaccine production. A toxoid vaccine is made from a toxin (poison) which has been made harmless. A diphtheria toxoid vaccine immunizes against diphtheria while a tetanus toxoid vaccine immunizes against tetanus.
A toxin treated so that it is no longer harmful but will induce antibodies to form. An example is tetanus toxoid.
A vaccine prepared from an inactivated bacterial toxin. (Botulinum toxoid vaccine and tetanus-diphtheria toxoid vaccines are examples.)
a toxin which has been modified so that it is no longer toxic, but which retains its antigenic functions. Can be used as a vaccine either alone, or in combination with anti-toxin molecules.
A modified bacterial toxin that has been rendered nontoxic (commonly with formaldehyde) but retains the ability to stimulate the formation of antitoxins (antibodies) and thus producing an active immunity. Examples include Botulinum, tetanus, and diphtheria toxoids.
A toxin which as been treated so as to destroy its toxicity but still leave it capable of stimulating the formation of antibodies when injected into the body.
A nontoxic derivative of a toxin used as an immunogen for the induction of antibodies capable of cross-reacting with the toxin.
A toxin that has been structurally altered to destroy its harmful properties without destroying its ability to induce formation of antibodies upon injection (i.e. tetanus toxoid)
A treated toxin that it is no longer poisonous, but is still able to cause the formation of antibodies that will neutralize it (e.g., tetanus toxoid). It is often used as a vaccine.
A toxoid is a bacterial toxin whose toxicity has been weakened or suppressed while other properties, typically immunogenicity, are maintained. Toxoids are used in vaccines as they induce an immune response to the original toxin or increase the response to another antigen. For example, the tetanus toxoid is derived from the tetanospasmin produced by Clostridium tetani and causing tetanus.
