[The role of immunization against bacterial enteric infections (author's transl)]

The author reviews critically the available vaccines against salmonellosis and shigellosis, the more sophisticated vaccines against these two infections and cholera presently under experimentation and using parenteral or oral dispensing. To contribute to public health planning, with particular reference to developping countries, the authors points on the necessity to evaluate carefully the merits of the different techniques aiming at controling bacterial enteric infections. Sanitation seems to be the most effective and the less expensive technique.
