The immunogenicity of proteins Sap and EA1, contained in B.anthracis S-layer, was evaluated in experiments on laboratory animals. These proteins were found to produce protective effect and could be regarded as additional immunogenic factors. The use of the newly constructed isogenic pair Sap+ and Sap- of B.anthracis strains made it possible to study the influence of Sap- mutation on the immunological properties of the causative agent of anthrax.
