Retrieved from ” https: Ticks and associated pathogens collected from dogs and cats in Belgium. Most of the signs and symptoms of ehrlichiosis can likely be ascribed to the immune dysregulation that it causes.

This strain, despite its tropism for platelets, is closely related to others identified in ruminants Zobba et al.
