Ehrlichia minasensis sp. nov., isolated from the tick Rhipicephalus microplus

International Journal of Systematic and Evolutionary Microbiology, 2016
Recently, we obtained a rickettsial isolate (Ehrlichia sp. UFMG-EVT) from the haemolymph of engorged Rhipicephalus microplus tick females. On the basis of maximum-likelihood phylogenetic analysis using 16S rRNA gene, groEL, dsb, gltA and trp36 sequences we showed that Ehrlichia sp. UFMG-EVT belongs to the α-Proteobacteria, family Anaplasmataceae, genus
