title: [The cell wall fractions of Brucella are specific mitogens. Implications in the genesis of the primary immune response].
abstract: Phenol-water extracts from smooth B. melitensis or B. abortus induce specific proliferation of lymphocytes from Brucella-sensitized men or animals. These extracts have no effect on lymphocytes of uninfected subjects. Above findings imply that an antigen will not trigger the so-called primary response when administered to a immune virgin animal.
