  • a SNP positions in the ORF of the TA system sgiAT are given according to ENA accession no. LT630458.

  • b The SGI1-PmMAT variant harbored the deletion created by ISVch4 and extending from within ORF S005 to within ORF S009 but without the presence of ISVch4 (18).

  • c The original SGI1 sequence (AF261825) showed 6 other specific SNP positions.

  • d The SGI1-F variant showed 5 other specific SNP positions.

  • e The SGI2 variant harbored 93 additional SNP positions and the transpositional insertion of the complex class 1 integron structure at a position different that in from all other variants (7, 8, 11, 14).
