The authors obtained and studied immunologically flagellae of S. typhi and flagellins (monomeric and polymeric) obtained from them. Immunological activity of flagellin was the greater the higher the molecular weight of the preparation (the polymer molecules were the largest and the most immunogenic). There were revealed differences between the preparations according to the dependence of the immunizing effect on the dose and the capacity to induce synthesis of 19S- and 7S-antibodies. A sharp change of the immunogenicity of flagellin preparation following gel-filtration through sepharose 2B was demonstrated.
