Phylogenetic relationships of groEL (a), gyrB (b), recA (c), and rpoB (d) genes between the L. hongkongensis HKU24T and other Leptotrichia species. The trees were constructed by the neighbor-joining method and bootstrap values were calculated from 1000 trees. The corresponding nucleotide sequences of Escherichia coli (NC_013364) were used as outgroups. The scale bar indicates the estimated number of substitutions per 50 bases. All names and accession numbers are given as cited in the GenBank database
