[Post-stress disorders of resistance of mice to recurrent infection by homologous influenza virus].

A decrease in the mouse resistance to reinfection by influenza virus under the effect of immobilization stress was depicted. Violation in the formation of a long-term resistance to a repeated disease ran in the presence of the high levels of circulating anti-influenza antibodies and not ++always correlated with a post-stress impairment of the formation of antigen-reactive clones of cells in the spleen of primarily infected mice. Prophylactic administration of ionol which prevented a post-stress aggravation of the primary influenza infection failed to produce a favourable effect on the immunity in case of reinfection.
