Phylogenetic relationships among partial 16S rDNA sequences (558 positions) of human (HF) and cow (CF) host-specific genetic markers identified from fecal clone libraries. The tree was inferred by using the neighbor-joining method. The numbers above the branch points are the percentages of bootstrap replicates that support the branching order. Bootstrap values less than 50% are not shown. Cytophaga fermentans was used to root the tree.
