This study identified the reactogenicity and immunogenicity of the antigen in the bacterial antigen and secrete antigen in emphysematous gangrene Clostridium, to provide experimental basis for the later emphysematous gangrene serological diagnostic methods to establish and vaccine development. 本研究确定了气肿疽梭菌的菌体抗原和分泌抗原中具有较好的反应原性和免疫原性的抗原,为以后气肿疽血清学诊断方法的建立和疫苗的研制提供实验依据。
