Acaricide potencial of andiroba (Carapa guianensis Aubl.) oil on engorged adult females of Anocentor nitens (Neumann, 1897) and Rhipicephalus sanguineus (Latreille, 1806) [PDF]
In vitro acaricide potential of the oil from andiroba seed (Carapa guianensis) was evaluated on engorged females of Anocentor nitens (n=210) and Rhipicephalus sanguineus (n=140) manually collected, from horses and dogs naturally infested, respectively ...

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