Table 2 Number of bacteria and B/E value in two groups (mean ± SD, LgN/g stool)

Bacteria (%)	IBS patients (n = 25)	Controls(n = 25)
Lactobacillus	6.79 ± 1.73 (92)	6.79 ± 1.94 (84)
Bifidobacteriaa	8.14 ± 2.14 (96)	9.32 ± 1.22 (100)

B/E valueb	0.91 ± 0.27 (96)	1.12 ± 0.23 (100)

The data in the bracket mean positive rate (This is applicable for the following tables including flora.).

^aP < 0.05 flora vs control,

^bP < 0.01 B/E value vs control,

^dP < 0.01 detection frequency vs control.
