Table 1 Prebiotic-associated changes in gut microbiota

Bacterial content	Ob-CT	Ob-Cell	Ob-Pre
Total bacteria	5.74^a (2.05)	4.30^b (0.38)	8.07^c (1.05)
Bifidobacterium spp	4.65^a (1.58)	3.38^b (0.37)	6.35^c (1.10)
Lactobacillus spp	4.93^a (1.76)	3.79^a (0.38)	7.16^b (1.40)
Clostridium coccoides–Eubacterium rectale cluster	3.65^a (1.37)	2.72^a (0.20)	6.41^b (1.27)

Results are given as the log DNA copies/caecal content (SD).
Data are mean with the SD.
Data with different superscript letters are significantly different p<0.05, according to the post hoc ANOVA statistical analysis.
CT, Cell and Pre, respectively, refer to the selected ob/ob mice fed a normal-diet, non-prebiotic control diet or prebiotic diet.
