Lactobacilli in fecal samples from the intervention study.
The levels of the different Lactobacillus species in fecal samples
of breast-fed infants and infants receiving a standard formula
or a standard formula supplemented with GOS/FOS
were determined with the duplex 5 nuclease assays. The number
of lactobacilli as a percentage of the total bacteria is shown
in Fig. 2. At the start of the study the percentages of lactobacilli
in the OSF and SF group were not statistically different (0.8%
0.3% and 0.5% 0.3%, respectively)
