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. info:eu-repo/grantAgreement/ES/DGA/A15-20R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.8 2023 VETERINARY SCIENCES 53 / 167 = 0.317 2023 Q2 T1 0.483 2023 Veterinary (miscellaneous) 2023 Q2 Medicine (miscellaneous) 2023 Q3 2.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ruiz de Arcaute, Marta Universidad de Zaragoza (orcid)0000-0002-7655-2472 Benito, Alfredo Ángel Villanueva-Saz, Sergio Universidad de Zaragoza (orcid)0000-0001-6209-4282 Calasanz Jiménez, José Lacasta, Delia Universidad de Zaragoza (orcid)0000-0002-7822-6646 1009 617 Universidad de Zaragoza Dpto.
