Nucleotide sequence alignment of a portion of the 16S-23S rRNA intergenic region of B. bacilliformis (GenBank accession no. L26364), B. clarridgeiae (GenBank accession no. AF167989), B. elizabethae (GenBank accession no. L35103), B. henselae (GenBank accession no. L35101), B. quintana (GenBank accession no. L35100), B. vinsonii (Baker strain) (GenBank accession no. L35102), B. vinsonii subsp. berkhoffii (GenBank accession no. AF167988), and B. abortus (GenBank accession no. X95889). The corresponding GenBank nt numbers are indicated at the beginnings and ends of the sequences. The thin-line arrows designate the original PCR primer positions. The thick-line arrow designates the position of the revised reverse primer.
