Abstract

Abstract:

In order to explore the restoration capability of Bifidobacteria on imbalanced flora in intestine, live bacteria (LB), cell-free extract (CE) and fermentation supernatant (FS) of Bifidobacteria were used to treat the vancomycin-induced mice model with imbalanced flora by gastric gavage. The effects of three different treatments of Bifidobacteria on major species of intestinal flora were evaluated. Results showed that three different treatments could significantly increase the proliferation of Bifidobacteria and Lactobacillia (P ＜ 0.01) and decrease the amounts of Clostridium perfringens and Enterococcus (P ＜ 0.05 and P ＜0.01). Bacteroide and Enterobacteriaceae were increased to the normal level. Therefore, LB, CE and FS of Bifidobacterium RH could restore and modulate the intestinal microecological balance of mice.

Key words: Bifidobacterium, ntestinal flora, imbalance, restoration
