a particular kind of antibody produced in the body in response to the presence of a toxin; see also immunity. adj., adj an´titoxic.
botulism antitoxin an equine antitoxin against the toxins produced by the types A and B and/ or E strains of Clostridium botulinum; administered intravenously in the postexposure prophylaxis and treatment of botulism, other than infant botulism. Generally trivalent (ABE) antitoxin is used.
diphtheria antitoxin equine antitoxin from horses immunized against diphtheria toxin or the toxoid; administered intramuscularly or intravenously in the treatment of suspected cases of diphtheria.
equine antitoxin an antitoxin derived from the blood of healthy horses immunized against a specific bacterial toxin.
tetanus antitoxin equine antitoxin from horses that have been immunized against tetanus toxin or toxoid; used for the passive prevention and treatment of tetanus. It is rarely used, tetanus immune globulin being preferred.

diph·the·ri·a an·ti·tox·in

antitoxin specific for the toxin of Corynebacterium diphtheriae.

diphtheria antitoxin

A preparation of horse antibodies to diphtheria used exclusively to treat suspected cases of diphtheria in which the risk of the disease exceeds the risk of the injection. The drug is not used as a diphtheria preventive because of the severe risk of hypersensitivity. The drug is on the WHO official list.

Age-Specific Immunity Levels to Diphtheria Antitoxin
The toxin inhibition test used to measure diphtheria antitoxin concentrations shows good correlation with the in vitro neutralization test in Vero cells, but is faster, simpler, and combines the measurement of diphtheria and tetanus antitoxin antibodies (8,9).
The sharp increase in the percentage of persons older than 44 years with no protective diphtheria antitoxin levels is consistent with findings of other studies (4,11,12,14-19).
However, relatively few 30- to 34-year-old persons (4.3%) who received their last vaccination approximately 25 years ago had a diphtheria antitoxin level of less than 0.01 IU/ml.
The patient was treated with parenteral penicillin and diphtheria antitoxin. His condition improved after 6 days of therapy.
As director of this laboratory, Smith undertook many practical and theoretical studies on the production of tetanus and diphtheria antitoxins. He was one of the first to demonstrate the production of immunity by killed cultures of disease organisms and to show that a mixture of diphtheria toxin and antitoxin confers immunity.
