title: Monitoring and survival of Lactobacillus gasseri SBT2055 in the human intestinal tract.
abstract: The monitoring and survival of Lactobacillus gasseri SBT2055 in the human intestinal tract was investigated with seven healthy subjects having a low number of fecal lactobacilli. An increase of fecal lactobacilli (10(3.2-5.2) CFU/g feces) was recognized after ingestion of yogurt with SBT2055 by the subjects. A high positive rate of L. gasseri in fecal lactobacilli detected from the subjects (over 70% at 2nd weeks of feeding) was also observed during the ingestion period using the species-specific PCR system. These findings indicate that the SBT2055 strain in yogurt survived in the human intestinal tract and was recovered from human feces.
