Genetic structures of the genomic regions franking oacC gene in serotype 6 strains. Sequences of contig NZ_AERO01000013 (strain CDC796-83), NZ_AKMW01000058 (CCH060), and SfII (NC_021857.1) were obtained from NCBI database. The orfs were annotated as submitted sequences in NCBI, and shown as thick arrows. The conserved genes of NZ_AERO01000013 and NZ_AKMW01000058 were shown in different colors: phage original genes, blue; IS629 and IS630, green; oacC, yellow; pseudo, gray; others, black. Genes sharing >95% identity at amino acid level between CDC796-83 and serotype-converting bacteriophage SfII are marked by red shadow. Functional domains of SfII are indicated below. Key primers used for PCR screening are indicated by thin arrows. The locus_tag numbers are showed in the arrows, and the encoded proteins are indicated above.
