The use of polyazolidineammonium and dimethyl-sulfoxide antigen Yersinia pseudotuberculosis to obtain hyperimmune serum

Abstract

The use of polyazolidinammonium modified with iodine hydrate ions (PAAG) as an adjuvant made it possible to obtain rabbit hyperimmune blood serums for dimethyl-sulfoxide antigen (DA) of a pseudotuberculosis microbe with generic specificity. Antibody titers in ELISA with Y. pseudotuberculosis and Y. enterocolitica cells amounted to 1:25600-1:12800, and with cells of other genera of intestinal microflora 1:100-1:400. The optimal immunizing dose for obtaining hyperimmune yersiniosis serum was a dose of 2 mg DA of Y. pseudotuberculosis per rabbit. Such a dose made it possible to obtain hyperimmune sera with a high titer of specific antibodies with a small consumption of antigen. The optimal concentration of PAAG solution for hyperimmunization of Y. pseudotuberculosis DA rabbits was 1%.
