Abundance and relative proportion of antimicrobial resistance gene (ARG) and metal and biocide resistant gene (MBRG) classes in different sample types. Abundance (a) is a measure of read counts aligning to ARG-MBRG database and normalized across samples whereas proportion (b) indicates percentage of each class in a sample type. The category ‘Other’ includes the rest of the low abundance ARG/MBRG classes for each sample type
