FIG. 2.

Complete FCT region of strain D471 and comparison to SF370. The percent nucleotide identity (nt id) between D471 and SF370 was established by pairwise BlastN 2 and is depicted for regions having ≥70% identity. The vertical dotted lines mark the FCT region boundaries for high nucleotide sequence identity. The distance scale (in kilobases) is shown for strain SF370; distances for D471 are presented for easy visual alignment but are not drawn precisely to scale. The sources for strain D471 sequences are GenBank (Table 1) and this study. The nomenclature for the protein F gene (prtF1) indicates its source as being an M type 6 strain (prtF1.6).
