The cytological findings in the bone marrow of both dogs were consistent with the hematological abnormalities concurrently found in the blood. National Center for Biotechnology InformationU. Serologic and clinical evidence of canine ehrlichiosis and serologic evidence of human ehrlichiosis have been reported in Chile 34. Anaplasma ovis infects goats and sheep and is usually non-pathogenic unless the animals are splenectomized.

Rev Med Chil ; Further studies are required to establish if the young age of the animals could represent a predisposing factor for platelet precursor infection.
Evidence of the zoonotic potential of A. In the present report, cellular inclusions were documented in bone marrow thrombocyte precursors of two young naturally infected dogs, indicating that A. Tetracyclines are the treatment of choice for all Anaplasma infections. Blood samples were obtained from 30 pet dogs seen in a private veterinary plafys in Santiago, Chile, with tick infestation and clinical signs compatible with ehrlichiosis hemorrhagic manifestations and thrombocytopenia.
