Fig. 3From: Phylogenetic relationship between the endosymbiont “Candidatus Riesia pediculicola” and its human louse hostProcrustean superimposition plot of Candidatus Riesia pediculicola and P. humanus. The extended principal coordinate matrices (X and Y) are centred by mean column vectors and subjected to Procrustes analysis. The configuration of the endosymbiont (dots) has been rotated and scaled to fit the lice configuration (arrowheads). Asterisk indicates lice samples, underlining indicates body lice.
