Identification of Rickettsia and Wolbachia bacterium at the species level. Phylogenetic trees based on the groEl gene showing the position of newly identified bacteria within the diversity of genera Rickettsia (left) and Wolbachia (right). We use different shapes to indicate location information and different colours to indicate habitat information. Specific groups such as the spotted fever group and mostly reproductive parasites are highlighted with a shaded box on the Rickettsia and Wolbachia trees, respectively.
