Changes in the gene copy numbers of lactobacilli in feces of probiotic and control groups. The gene copy numbers of total lactobacilli per gram of feces were determined usingreal-time PCR assay with specific primers. The counts of total lactobacilli decreased in the control group (n = 15, P = 0.056), not in the probiotic group (n = 25, P = 0.497). Dot plots indicate max-min, median, and 1st and 3rd quartiles.
