Profile of gut microbiota of the tested mice. Denaturing gradient gel electrophoresis (DGGE) banding patterns obtained with universal ( A ) and Lactobacillus -specific ( B ) primers. The comparison based on profile similarities calculated using the Pearson’s correlation coefficient, dendrogram constructed using unweighted pair group method with arithmetic mean (UPGMA). Mice groups: S-PBS—sensitized with a mixture of α-casein and β-lactoglobulin (α-CN + β-LG −200 μg of protein/100 μL of mixture) with aluminum adjuvant (1:1 vol / vol ) and treated with phosphate-buffered saline (PBS), S-M—sensitized and treated with milk, S-YM—sensitized and treated with YM yogurt drink fermented with S. thermophilus 2K + L. bulgaricus BK starter set, S-YM-LB—sensitized and treated with YM-LB yogurt drink fermented B. lactis Bi30 + L. plantarum W42 + S. thermophilus 2K + L. bulgaricus BK bacterial set. Results of identification of the sequenced bands of lactobacilli: (band 1, 3)— Lactobacillus reuteri (98–100% sequence similarity), (band 2, 5, 6)— Lactobacillus gasseri (98%), (band 4)— lactobacillus murinus (98%), (band 7)— Lactobacillus bulgaricus (98).
