Figure 1. Alignment of DNA sequences for sec genes of three investigated isolates of S. pseudintermedius and reference sequences of S. intermedius canine subtype, and S. aureus sec 1–3 subtype. The EMBL accession numbers of the sec nucleotide sequences used for the alignment are as follows: sec_canine, U91526; sec_1, X05815; sec₂, DQ192646; sec₃, X51661. The sequences of the three S. aureus subtypes were merged, since there were not differences in the aligned region as showed here. Dots indicate identity.
