| Human science employs somewhat similar procedures to produce what are called antitoxins, protein antibodies, to certain microorganisms. |
| Antivenoms and antitoxins can also be administered in this fashion. |
| For example, antitoxins, like tetanus antitoxin, are made by injecting horses with a small amount of the toxin so that the animal produces the antibodies. |
| In Berlin, Koch's assistants had discovered the principle of passive immunity and antitoxins. |
| Some antibodies are antitoxins, which directly neutralize any toxins secreted by the antigens. |
| Perhaps the military who wanted the antitoxins for germ warfare were waiting quietly for him either to talk or die. |
