Abstract : Insect intracellular symbiotic bacteria (intracellular endosymbionts, or endocytobionts) were positioned within the gamma 3-Proteobacteria using a non-homogeneous model of DNA evolution, allowing for rate variability among sites, for GC content heterogeneity among sequences, and applied to a maximum likelihood framework. Most of them were found to be closely related within the Enterobacteriaceae family, located between Proteus and Yersinia. These results suggest that such a bacterial group might possess several traits allowing for insect infection and the stable establishment of symbiotic relationships and that this could represent a stem clade for numerous insect endocytobionts. Based on the estimations of the equilibrium GC content and branch lengths in the phylogenetic tree, we have made comparisons of the relative ages of these different symbioses.
