Survival of<i>Lactobacillus casei</i>in the Human Digestive Tract after Consumption of Fermented Milk

Abstract

A human trial was carried out to assess the ileal and fecal survival of Lactobacillus casei DN-114 001 ingested in fermented milk. Survival rates were up to 51.2% in the ileum and 28.4% in the feces. The probiotic bacterium has the capacity to survive during its transit through the human gut.
