FIG. 1.

DNA sequence alignment of FHBP from prototype strains. FHBP from strains MC58 (variant 1; GenBank accession no. AE002098), 961-5945 (variant 2; DQ523568), and M1239 (DQ523569) were aligned using ClustalW (3). The variant 1- and 2-specific (v.1,2) primers are shown above the alignment, and the variant 2- and 3-specific (v.2,3) primers are shown below the alignment. Where the primer sequences differ from one of the FHBP sequences, an asterisk is shown adjacent to the divergent sequence. Only the regions used for primer design are shown; the numbering with respect to the full-length open reading frames is shown at the right.
