Revista Brasileira de Parasitologia Veterinária, 2012 Acaricide resistance has become widespread in countries where cattle ticks, Rhipicephalus (Boophilus) microplus, are a problem. Resistance arises through genetic changes in a cattle tick population that causes modifications to the target site, increased metabolism or sequestration of the acaricide, or reduced ability of the acaricide to penetrate ...

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
