Answer

After ingestion by phagocytes, about 15-30% of brucellae survive. Susceptibility to intracellular killing differs among species, with B abortus readily killed and B melitensis rarely affected; these differences might explain the differences in pathogenicity and clinical manifestations in human cases of brucellosis.
