FIG. 3.

Phylogenetic dendogram based on a neighbor-joining comparison of 1,330-nucleotide sequences of 16S rRNA genes. The scale bar at the bottom of the dendrogram represents a 1% difference. The strain designations and accession numbers for the sequences retrieved from GenBank are as follows: B. clarridgeiae CIP 104772, accession no. X97822; B. bacilliformis, accession no. M65249; B. henselae, accession no. M73229; B. quintana, accession no. U28268; B. grahamii V2, accession no. Z31349; B. elizabethae ATCC 49927, accession no. L01260; B. vinsonii subsp. berkhoffii G7464, accession no. U26258; B. taylorii M6, accession no. Z31350; B. doshiae R18, accession no. Z31351; B. vinsonii ATCC VR-152, accession no. L01259; and B. abortus 11-19, accession no. X13695.
