摘要：
The present invention is an improved vaccine against Brucella abortus which permits differentiation between vaccinated and field strain infected cattle. The vaccine can be administered in two different forms: (1) cell envelopes isolated from an O polysaccharide antigen deficient, stable transposon mutant of B. abortus or (2) an O polysaccharide antigen deficient, stable transposon mutant of B. abortus.
