M. G.  aIdentification of new genes in cattle of different genetic groups activated in response to tick Rhipicephalus (Boophilus) microplus.h[electronic resource]  aArchivos Latinoamericano de Producion Animal, v. 19, (supl. 1), p. 221c2011  aOne of the main constraints in Brazilian cattle production and many tropical countries are caused by parasitism of Rhipicephalus microplus tick. In order to understand the host - parasite relationship, this study evaluated CHI3L2, CXCL5, IGHG1, ISG15 and PGLYRP1 gene expression in three genetic groups of cattle infested with R. microplus tick. For this, skin samples from 45 Nellore and crossbreed females, Senepol x Nellore and Angus x Nellore were collected before the 1 st infestation and 24 hours after the 4th infestation with 20,000 R. microplus larvae.  aGene expression  aBoophilus Microplus  aGene  aCarrapato Rhipicephalus microplus  aExpressão gênica  aIdentification  aRhipicephalus (boophilus microplus)  aTick1 aGIACHETTO, P.
