Strain-Specificity of Complement-Fixation with Sera of Mice Immune to the Virus of Influenza A and Swine Influenza

[摘要] The sera of mice immunized with human and porcine strains of influenzal virus exhibit strain-specificity by complement-fixation in that the titer is almost always higher with the homologous antigen.The antigen-antibody curves for human and porcine influenzal antigens prepared from infected mouse-lungs and tested against immune mouse serum differ in form.The strain-specificity observed with complement-fixation is less definite than that found by neutralization tests with the same samples of mouse serum.The serum of human beings convalescent from influenza does not show strain-specificity by complement-fixation.
