- Abstract
Lactobacillus casei strain Shirota (LcS) and Bifidobacterium breve strain Yakult (BbrY) are probiotics that have been provided to consumers for many years and are reported to have beneficial effects on human health. Especially, "Yakult", a fermented milk beverage containing 6.5 billion live LcS, is drunk in more than 32 countries and regions worldwide, including in Japan, with more than 30 million products being provided to the market each day. This widespread mass consumption o f this probiotic product has been achieved with the help of product delivery and sales staff. They provide the fresh probiotic drink to customers each day, and naturally they personally consume this probiotic beverage at high rates. Assuming that the effect of probiotics in improving intestinal microbiota would be observable in the staff routinely consuming the products, we compared the intestinal microbiota of 91 staff with that of 98 women from the general population who were not in the habit of drinking probiotic products. We found that 1) the frequencies of detection o f LcS and BbrY in the feces were higher in the staff than in the general group of women; 2) counts of bacteria, including Bifidobacterium, the Clostridium coccoides group, the Bacteroides fragilis group, Enterococcus, and Lactobacillus, were significantly higher in the staff group than in the general group, whereas the frequencies of detection and counts of Prevotella, Staphylococcus, and C. perfringens were significantly lower in the staff group than in the general group; 3) the stools of the staff group were significantly softer than those of the general group . These results suggested that regular drinking of probiotic products improved the intestinal microbiota and bowel habit in these staff.
