title: [Immunosuppression induced by respiratory viruses (influenza virus, adenovirus) in mice].
abstract: The influence of respiratory viruses (adenovirus, influenza virus) on humoral immune response to heterologous T-dependent and T-independent antigens was studied. It was shown that inoculation of mice by the influenza virus (A/PR8/34-A/PR/8) 3 days before sheep red blood cells administration led to the inhibition of antibody forming cell (AFC) and immunoglobulin, forming cell (IFC) increase on 69% and 59% respectively. Adenovirus type 6 induced the similar suppression of AFC and IFC formation. Thus, viruses induced immuno-suppression, which was polyclonal. It was also shown that virus of one strain (type) could inhibit immune response to another strain (type) of virus. The immune response to T-independent antigen was not suppressed. The virus-induced immunosuppression was dependent on: 1) the infectivity of respiratory viruses, 2) the route of virus and heterologous antigen injection, and 3) the interval between the viruses and antigen inoculation.
