*UAE, United Arab Emirates; –,no known insertion sequences were identified. Blank cells indicate that the information is not available.
†Carries mcr-1.3 variant (AA111–2GG) encoding MCR-1.3 with a single (Ile38Val) change from MCR-1 (10).
‡This information is assumed from a GenBank entry rather than from a published report.
§This plasmid has many missing or extra nucleotides in homopolymeric regions compared with all other related plasmids.
