Effects of two types of prebiotics on the intestinal environment and the antibody titers in patients receiving enteral tube feeding: an open-label, randomised controlled trial - Effects of two types of prebiotics on the intestinal environment and acquired immunity

Although there was little difference in the Bifidobacterium count in C group during study period, the Bifidobacterium count in F group increased (about 10-fold). The enhanced HI antibody titers against A/H1N1 and A/H3N2 were maintained in F group for a longer period compared with C group. The seroprotective rates against A/H3N2 in F group at week 6 after influenza vaccination were significantly higher than those in C group.
