Figure 2. Phylogenetic tree showing the relationship of a 4,834-bp fragment of the outer membrane protein B gene of Candidatus Rickettsia tasmanensis (in boldface) among all validated rickettsia species. The tree was prepared by using the neighbor-joining algorithm within the MEGA 4 software (10). Bootstrap values are indicated at each node. Scale bar indicates 2% nucleotide divergence.
