An impact of the gut flora, the microbiota, on the modulation of allergies has been suspected for many years. Among non-pathogenic, colonizing organisms of the gut, probiotics play a special role in this regard and many experimental and clinical studies have focused on these micro-organisms. The presentation will first address immunologic concepts which are the basis of a potential action of probiotics, by presenting mostly experimental studies in animals. In the second part, clinical studies will be presented and will address mostly the timing of administration of probiotics, as well as specific effect on atopic disease prevention that have been studied. Finally, a critical review and interpretation based on the clinical studies available will be provided. The presentation should allow the attendance to understand which effect might be obtained by probiotics for prevention of atopic diseases.
