  1. The OTU assignments were made using the Ribosomal Database Project classifier in QIIME. The mean and standard error (S.E.) of the percentage of reads that map to the respective genus is provided. If the OTU was not assigned to a known genus its nearest available taxonomic rank is provided. F = Family, O = Order, P = Phylum. *Significant differences between groups (P = 0.03 and 0.01, respectively).
