Summary: | Ovine anaplasmosis is an emerging vector-borne disease in Europe caused by
Anaplasma ovis
. 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. |
