Answer

Development of cell-mediated immunity is the principal mechanism of recovery. The host response to infection with B abortus is characterized by the development of tissue granulomas indistinguishable from those of sarcoidosis. In contrast, infection with the more virulent species (B melitensis and B suis) more commonly results in visceral microabscesses.
