Fig. 3: The risk ranks of 37 known high risk ARG families identified by World Health Organization (WHO) and literature review (highlighted in dark purple) (referred to as “listed” ARGs), 73 Rank I ARG families of the initial set, and 19 Rank II ARG families of the initial set.
From: An omics-based framework for assessing the health risk of antimicrobial resistance genes

“Listed” (WHO-listed) represented Rank I ARGs that were reported to cause problems in hospitals and/or have been widespread on mobile genetic elements by previous literatures (highlighted in dark purple). “Unlisted” represented Rank I ARG families that were not reported in previous studies as high risk ARGs. “Homologs in Rank I” represented Rank II ARGs with homologous Rank I ARGs of the same gene family (highlighted in light purple). ARGs antibiotic resistance genes.
