[Study of antibodies to heterologous connective tissue, isolated from sera of patients with rheumatism].

Antibodies against connective tissue elements of various bovine organs were isolated from the sera of rheumatic fever patients with the aid of immunosorbents (bovine connective tissue extract and erythrocyte stroma). The antibody preparations obtained were not identical and contained antibodies against different antigens of bovine connective tissue. The antibody preparations failed to react with human connective tissue components.
