title: [Delayed hypersensitivity and nonspecific cellular immunity. The conditions determining the maximally expressed immunity activity].
abstract: In vivo experiments on the infection of mice with influenza A virus and Francisella tularensis and in vitro experiments on the bactericidal activity of macrophages have demonstrated the conditions leading to the maximally pronounced activation of immunity by means of preparations inducing delayed hypersensitivity (DH). The following conditions have been determined: the presence of pronounced DH previously to the injection of old tuberculin (OT) and staphylococcal phagolysate (SP) used as challenge antigens, the specificity and peculiar features of the antigenic structure of the challenge agent, the time of its administration after the course of multiple sensitizing injections of BCG and staphylococci, the dosage of OT and SP and the scheme of their administration, the desirability of their local use. The time of the maximum activation of cell-mediated immunity after the injection of OT and SP to sensitized animals with a high level of DH and the duration of such activation have been established.
