AA, amino acid; C/T, ceftolozane/tazobactam.
Amino acid changes are greater relative to reference sequences.
Threshold for β-lactamase gene inclusion was 72% and 80% for minimum nucleotide sequence identity and minimum sequence length, respectively.
Novel MLSTs were given sequential designations for clarity.
