Fig 4. Distribution of NadA variants and peptides in the 300 isolates panel.

Frameshift¹: The nadA nucleotide allele presents a frameshift mutation resulting in a premature stop codon (variant 1 allele 44; variant 4/5 alleles 12, 34, 38, 39, 40 and 46; variant 6 alleles 37, 43 and 94). IS1301²: The nadA gene (allele 50) is disrupted by an insertion sequence IS1301. NA³: Clonal complex non assigned.
