RESUMO

The immunofluorescent and immunoperoxidase cell-counting techniques were comparable in precision and reproducibility for the quantitative assessment of influenza virus infectivity. The dose-response function was linear with each procedure, and comparable results were obtained for estimating neutralizing antibodies in antiviral serum.
