AB Phylogenetic trees based on the 16S rRNA (A) and groEL (B) genes sequences from members of the family Anaplasmataceae. The tree shows that E. mineirensis (UFMG-EV) falls in a clade separated from all the previous reported sequences. Bootstrap values are shown as % in the internal branch. Only bootstrap values equal or higher than 50% are shown. Rickettsia prowazekii 16S rRNA sequence was used to root the 16S rRNA tree and E.coli groEL gene was used to root the groEL tree. The GenBank accession numbers of the sequences used to build the 16S rRNA tree are: E. muris, AB013008; E. chaffeensis, AF147752; E. ruminantium, AF069758; E. ewingii, U96436; A. marginale, M60313; A. phagocytophilum, M73224; A. platys, M82801; N. helminthoeca, U12457; N. sennetsu, M73225; N. risticii, AF036649; E. canis, GU810149; R. prowazekii, NR044656. The GenBank accession numbers of the sequences used to build the groEL tree are: E. muris, AF210459; E. chaffeensis, L10917; E. ruminantium, U13638 ; E. ewingii, AF195273; A. marginale, AF165812; A. phagocytophilum, U96729; A. platys, AY008300; N. sennetsu, U88092; N. risticii, U96732; E. canis, U96731; E. coli, X07850.
