title: Thymus-independent antibody production to the antigen of Rickettsia prowazekii.
abstract: Antibody production has been studied in cotton B-rats and in CBA B-mice during immunization with chemical typhus vaccine (CTV) and during infection with Rickettsia prowazekii. Studies of the immune response to rickettsial antigen in T-deficient animals have shown a high immunogenicity of CTV and independence of antibody production on T-lymphocytes. Active antibody synthesis was also observed in B-rats and B-mice during Rickettsia prowazekii infection. The absence of T-lymphocyte dependence in experimental animals was tested by administration of sheep red blood cells (SRBC).
