The infection has spread quickly in recent years, causing moderate to severe outbreaks in sheep flocks, leading to relevant economic losses in sheep farming. This wider spread has been associated with global warming and climate change, favouring the maintenance and life cycle of their main vector, the ticks. However, another epidemiological aspect could favour this quick spread. Long persistence infection of Anaplasma ovis has been proposed as a hypothesis in several articles but never scientifically proven. The results of the present study demonstrate that eight adult sheep, both naturally or experimentally infected, maintain Anaplasma ovis load in blood during their whole productive life (4 to 6 years), being permanently infected. In addition, the results suggest that A. ovis bacterial load can be constant or suffer fluctuations, as has been demonstrated in other Anaplasma species. Both aspects can be determinants in the epidemiology and the transmission of the infection. 000128188 536__ $$9info:eu-repo/grantAgreement/ES/DGA/A15-20R 000128188 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000128188 590__ $$a1.8$$b2023 000128188 592__ $$a0.483$$b2023 000128188 591__ $$aVETERINARY SCIENCES$$b53 / 167 = 0.317$$c2023$$dQ2$$eT1 000128188 593__ $$aVeterinary (miscellaneous)$$c2023$$dQ2 000128188 593__ $$aMedicine (miscellaneous)$$c2023$$dQ3 000128188 594__ $$a2.5$$b2023 000128188 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000128188 700__ $$0(orcid)0000-0002-7655-2472$$aRuiz de Arcaute, Marta$$uUniversidad de Zaragoza 000128188 700__ $$aBenito, Alfredo Ángel 000128188 700__ $$0(orcid)0000-0001-6209-4282$$aVillanueva-Saz, Sergio$$uUniversidad de Zaragoza 000128188 700__ $$aCalasanz Jiménez, José 000128188 700__ $$0(orcid)0000-0002-7822-6646$$aLacasta, Delia$$uUniversidad de Zaragoza 000128188 7102_ $$11009$$2617$$aUniversidad de Zaragoza$$bDpto.
