[Effect of gamma irradiation on the immunological properties of the brucellar protective antigen]. / Vliianie gamma-oblucheniia na immunologicheskie svoistva brutselleznogo protektivnogo antigena.

ABSTRACT

It was shown that the splenocytic response to mitogens in guinea pigs was activated 7 days following immunization thereof with a gamma-irradiated brucellar protective agent (gamma-BPA), while nonirradiated BPA inhibited lymphocyte proliferation under the effect of mitogens. gamma-BPA, as compared with BPA, circulated in blood for a longer time, induced a more rapid and prolonged synthesis of antibodies, and provided the development of a more intensive immunity.
