[Effect of trypsin on the immune response in localized staphylococcal infection]

The influence of trypsin on the formation of immune response induced by a thymus-dependent antigen at different periods of localized staphylococcal infection has been studied. A single intramuscular injection of bovine trypsin has been found to enhance immune response to sheep red blood cells (SRBC) in healthy mice and, to a still greater degree, in mice with localized staphylococcal infection. the development of localized staphylococcal infection has been shown to have no influence on the manifestation of the immuno-suppressive effect of splenocytes in SRBC-immunized mice or to enhance this effect. The injection of trypsin decreases the immunosuppressive effect of splenocytes in healthy or staphylococcus-infected hyperimmune mice.
