FIG. 1.

Phylogenetic analysis of the translated Rep sequences amplified by pan-Rep PCR. Sequences derived from human stool samples (red), chimpanzee stool samples (purple), and farm animal meat samples (green) are indicated. Cycloviruses in the same species are defined as having >85% identity in Rep region and are labeled by vertical bars 1 to 25. The scale bar labeled 0.05 at the bottom of the figure represents 5% estimated phylogenetic divergence. The countries of origin are Pakistan (PK), Nigeria (NG), Tunisia (TN), and the United States (US).
