    Recently, we obtained a rickettsial isolate (Ehrlichia sp. UFMG-EV) from the hemolymph of Rhipicephalus microplus engorged tick females. On the basis of maximum likelihood phylogenetic analysis using 16S rRNA, groEL, dsb, gltA and trp36 nucleotide sequences we showed that Ehrlichia sp. UFMG-EV belongs to the α-Proteobacteria, family Anaplasmataceae, genus Ehrlichia. Ehrlichia sp. UFMG-EV is a sister taxa of E. canis with 16S rRNA, groEL, dsb, gltA and trp36 nucleotide sequence similarity of 98.3%, 97.2%, 94.7%, 94.3% and 49.1%, respectively. Ehrlichia sp. UFMG-EV has been maintained in the laboratory by continuous passage in the IDE8 tick cell line where the ultrastructure was characterized using electron microscopy and it resembles that of E. canis, E. muris and E. chaffensis, but not E. ruminantium and E. ewingii. We propose the name Ehrlichia minasensis sp. nov. for this bacterium to acknowledge the place from where it was isolate for first time, Minas Gerais, Brazil. The type strain of Ehrlichia minasensis sp. nov. is strain Ehrlichia sp. UFMG-EV (= DSM 100393, = TCB-TBB-0018).
