Antibiotic resistance determinants identified by whole-metagenome shotgun sequencing of metagenomic libraries. (A) Classes of antimicrobials to which resistance determinants were identified, normalized as copies per million paired-end reads per sample source. (B) Phylum-level classification of AR determinants normalized as copies per million paired-end reads per class. Reads which could not be classified by Kraken2 are labeled unclassified, while reads which could not be classified to a phylum are labeled unassigned. (C) Species-level classification of AR determinants normalized as copies per million paired-end reads per class. Reads which could not be classified by Kraken2 are labeled unclassified, while reads which could not be classified to a species are labeled unassigned.
