Changes in the ecologic diversity of the cecal microbiota in vancomycin treated mice

		Observed richness	Chao1 richness estimator (95% c.i.)	Shannon diversity index (95% c.i.)
Cecal mucosa	Control	107	151 (128–198)	3.90 (3.75–4.05)
	Vancomycin	12	15 (12–35)	1.87 (1.74–1.99)*
	Recovered	83	96 (88–117)	4.04 (3.92–4.15)
Cecal contents	Control	117	168 (142–220)	4.26 (4.14–4.38)
	Vancomycin	6	7 (6–20)	0.74 (0.59–0.88)*
	Recovered	61	86 (70–129)	3.48 (3.34–3.62)

^*significantly different when compared to control and recovered groups, p < 0.01; unpaired t-test.
