Primary Prevention of Allergic Disease in Early Child by Lactobacillus Reuteri

The mothers started taking Lactobacillus reuteri ATCC 55730 (BioGaia AB, Stockholm, Sweden) or placebo four weeks before term and continued to do so daily until delivery. After birth, the baby commenced with the same study product as the mother at 1-3 days of age and continued daily for one year. The daily intake, five oil droplets, corresponded to 1 x 100 000 000 colony forming units (CFU)

The placebo consists of the same oil that the active study product but without any bacteria and is not possible to differentiate from the active product by smell, taste or visual appearance
