title: [Laboratory procedures in adenoviruses. IV. The influence of antiglobulin and complement on neutralization and hemagglutination-inhibition (author's transl)].
abstract: The neutralization of adenovirus 3,7, and 19 by rabbit antisera is enhanced by additional application of antirabbit globulin. All sera investigated, obtained early or late after the start of immunization, showed two- to sixfold titer rises. Complement also enhances the neutralization; the titer is raised to a greater extent in early than in late sera. To achieve maximal effects, antiglobulin and complement had to be used in fairly high concentration (ca. 10%). In hemagglutination-inhibition the same set of sera showed a titer increase mediated by anti-rabbit globulin (mostly by the factor 2 to 4), while complement was without influence. The neutralization titer of human sera from patients with adenovirus infections, as opposed to the rabbit antisera, was only slightly increased by addition of anti-human globulin or complement. These reagents had likewise negligible influence on the hemagglutination-inhibition of adenovirus 8 by human sera.
