Abstract
Lines of virus derived from a single throat washing by isolation and transfers in different hosts were compared in cross tests with antisera from several species. Variations in antigenic potency and avidity for antibody were noted especially with viruses after passages in mice or in chorioallantoic membrane tissue culture.
