(UNDER CONSTRUCTION : )
We plan to provide detailed information concerning the phylogenetic relationships of different isolates as determined by the genes that we have introduced in our pages on molecular genetics.
As a first introduction, we present below a figure taken from our review paper, that shows the inter-strain relationships between a large number of isolates examined for variation at the 56kDa TSA gene.
The root of the tree represents the branch leading to more distant organisms. First to be found as the tree would be traced backwards would be the lineage now defined by Candidatus O. chuto. Presumably other scrub-typhus-like organisms, such as the organism identified in Chile, would also branch from common ancestors of all taxa within Orientia. Further down the branch would be the common ancestor between Orientia and the members of the genus Rickettsia.
FUTURE ADDITIONS:
information concerning individual genes (up to 20 or more).
specific information on attempts to provide a MLST analysis of inter-strain relationships and the relationships between isolates based on whole genome data.
