Table 3

Influence of Mutaflor (Escherichia coli Nissle 1917), rifaximin, and colitis applied alone or in their combination on the number of Enterococcus spp. identified by qPCR in feces samples.

Experimental groups	The number of bacteria (CFU/g)
Control	3.54 × 10^7 ± 5.90 × 10^4
Mutaflor	3.23 × 10^5 ± 5.73 ×
Rifaximin	6.88 × 10^1 ± 3.78 ×
Rifaximin + Mutaflor	3.59 × 10^2 ± 7.69 ×
Colitis + NaCl	4.34 × 10^8 ± 5.68 ×
Colitis + Mutaflor	2.45 × 10^7 ± 3.22 ×
Colitis + rifaximin	1.45 × 10^2 ± 7.26 ×
Colitis + rifaximin + Mutaflor	6.34 × 10^4 ± 7.05 ×

Mean value ± SEM. observations in each experimental group. compared to control; compared to colitis + NaCl; and compared to colitis + Mutaflor.
