TABLE 3.
Distribution of bifidobacterial species by different enumeration methods
| Species | % of total bifidobacteriaa
|
|||
|---|---|---|---|---|
| BFM | BS medium | TE medium | GC-16S | |
| B. longum | 100 | 83 | 42 | 15 |
| B. adolescentis | 0 | 17 | 58 | 85 |
a
At the 95% confidence level, the abundance of B. adolescentis on BFM and BS medium did not differ significantly, while the abundance on TE medium was higher than that on BFM or BS medium (P < 0.05). The GC-16S method allowed for a higher abundance of B. adolescentis than any of the culture-based methods (P < 0.05).
