Construction of ARG-sharing networks based on metagenomes. a Contigs and their functional genes were annotated as bacterial genus and ARGs, respectively. b BLASTn Sequence identity was computed for each pair of functional genes annotated as ARGs. A pair of genes was assumed to represent the same ARG if its BLASTn sequence identity was 100%. c In the global network, genera were connected if their contigs shared ā„1 ARG of any type in ā„1 sample among those collected from a given animal species, whereas only the ARG of interest was considered in the ARG-specific network
