[Reactivity and immunogenicity of the Sonne dysentery detergent monovaccine].

The authors elaborated a method of isolation under industrial conditions of Shigella sonnei surface antigens by the treatment of the culture with a detergent (sodium laurylsulfate). The antigens obtained possessed a much lesser toxicity in comparison with the tryptic ones. A method of preparation of a detergent Sonne monovaccine with an increased antigen content (1.3 mg/ml) was described. Experimental series of the preparation were tested on 38 volunteers. A lower reactogenicity of the detergent vaccine (in comparison with the tryptic) and its marked immunological efficacy was demonstrated.
