TABLE 1.

The microbiota colonization in indicated gnotobiotic animals.

Microbiota	Inoculation	Fecal (1st)	Fecal (2nd)	Fecal (3rd)
Germ Free	saline	0	0	0
E. rectale	1 (10^10)	6.8 ± 0.1a(10^5)	8.2 ± 0.2b(10^5)	1.2 ± 0.2c(10^6)
L. plantarum	1 (10^10)	7.8 ± 0.3 (10^8)	7.6 ± 0.2 (10^8)	7.8 ± 0.2 (10^8)
C. coccoides	1 (10^10)	6.4 ± 0.1 (10^6)	6.5 ± 0.3 (10^6)	6.8 ± 0.6 (10^6)

The indicated microbiota was inoculated 0.5 mL by oral gavage and simultaneously analyzed the fecal for specific microbiota content every 2 weeks. The unit of table was represented as CFU/g (fecal). Values in the same row with different superscript letters (a,b,c) differ significantly, p < 0.05, by repeated ANOVA.
