Figure 3. Principal component analysis of 26 metagenomes based on RATC genes.

Figure 3

Information regarding resistance to antibiotic and toxic compounds (RATC) was used to perform a principal component analysis of 26 publicly available metagenomes. Both animal agriculture and human associated metagenomes group in quadrant three. Eigenvectors for quadrant three included tetracycline, aminoglycoside adenyltransferase, and multi-drug resistance efflux pump genes.
