ARG quantification relative to 16S rRNA gene copies as detected. Left qPCR: a Total counts of ARGs normalized to 16S rRNA gene copies; b Proportional abundance of each ARG relative to 16S rRNA gene copies. Right MGS: c Total counts of ARGs normalized to 16S rRNA gene copies; d Proportional abundance of each ARG relative to 16S rRNA gene copies
