	Total # of taxa	# of common taxa (%)	# of subject-specific taxa (%)

Class	15	4 (26.7)	1 (6.7)
Order	32	6 (18.8)	1 (3.1)
Family	57	9 (15.8)	2 (3.5)
Genus	81	8 (9.9)	1 (1.2)

Distinct sequences (100%-ID phylotypes)	3011	9 (0.3)	69 (2.3)

Taxa found in the three time-point samples of all subjects are designated as common. Subject-specific taxa correspond to those found in the three time-point samples from some subjects and absent in the three time-point samples from the others. Taxa (phylum to genus) were identified using MG-RAST with a minimum alignment length of 105, the RDP dataset option and a maximum e-value of 10^-30 [12]. OTUs₀₀₃ were defined using CD-HIT [33], and include the hypervariable regions.
