Quizplus · Accepted Answer

Antibodies against diphtheria toxin can be produced in response to vaccination or previous infection with the bacterium that causes diphtheria. However, the presence of antibodies alone does not necessarily indicate current or past infection. It is possible that the patient was in close contact with someone who had the disease, leading to the production of antibodies.
