Resumen:
The aim of this study was to investigate if there is a phylogenetic divergence of Rickettsia amblyommatis strainsfrom different phytogeographic provinces of Argentina and South America. Therefore, ompA and ompB genesequences of R. amblyommatis DNA detected in Amblyomma hadanii and Amblyomma neumanni ticks from theYungas and Chaco phytogeographic provinces, respectively, were obtained. These sequences were comparedwith GenBank sequences from R. amblyommatis from different countries of the American continent. The analysesshown that ompA haplotypes of R. amblyommatis form two clusters which differ phylogenetically. Regarding toompB sequences, three groups of R. amblyommatis strains were detected. It could be shown that strains of R.amblyommatis detected in A. hadanii from the phytogeographic province Yungas are phylogenetic different tothem detected in A. neumanni from the phytogeographic province Chaco. Furthermore, it could be observed thatstrains detected in different tick species associated with different phytogeographic provinces of the Americancontinent differ phylogenetically.
