title: [Identification of heterologous antitoxin in sera of patients with diphtheria].
abstract: Using immobilized diphtheria toxin and peroxidase conjugate of monoclonal antibodies to light chains of equine immunoglobulin a method of quantification of equine antibodies against diphtheria in sera of patients after serotherapy was developed. The sensitivity of indirect enzyme-linked immunosorbent assay was 0.0005 IU/ml, and coefficient of variation did not exceed 10%. It was shown that in patients with toxic diphtheria heterologous antitoxin is eliminated within 4-6 weeks. Level of anti-diphtheria immunoglobulin under the similar severity of disease and dosage of antitoxin can vary in wide ranges and depends from individual's characteristics.
