Phylogenetic tree of two types of Coxiella -like bacteria based on 16S rRNA gene sequence similarity. The tree was rooted with Bacillus subtilis (GenBank: X60646) and constructed using neighbour-joining method and clustering nodes were also recovered in maximum likelihood method. Numbers at nodes represent the levels of bootstrap support (%) based on neighbour-joining analysis of 1000 replicated data sets. GenBank accession numbers are given in parentheses. Bar represents 2% sequence divergence.
