Anaplasma ovis infects goats and sheep and is usually non-pathogenic unless the animals are splenectomized. This rickettsial pathogen has a wide geographic distribution, including in the Americas, Africa, Asia, the Middle East, southern Europe, and Australia 678and is believed to be transmitted by ticks, as A.

In the present report, cellular inclusions were documented in bone marrow thrombocyte precursors of two young naturally infected dogs, indicating that A. National Center for Biotechnology InformationU. Archivos de Medicina Veterinaria. Abstract Anaplasma platys is an obligate intracellular rickettsial pathogen that infects platelets of dogs, forming basophilic intracellular morulae.

The organisms are anaplzsma by ticks, particularly Ixodes species, with rodents and deer serving as reservoir hosts in the northeastern United States, white-footed mice are the implicated main reservoir of not only Anaplasma but also Borrelia burgdorferi.

Megakaryocytic emperipolesis, the movement of blood cells erythrocytes, neutrophils, and lymphocytes within megakaryocytes 23was observed in the bone marrow of both dogs.

Articles with ‘species’ microformats All stub articles. Anaplasma marginale is an i ntracellular erythroparasite of cattle that produces severe hemolytic anemia and is of major economic importance. Ehrlichioses are recognized as important emerging tickborne diseases in humans and wild and domestic animals. Blood samples were obtained from 30 pet dogs seen in a private veterinary clinic in Santiago, Chile, with tick infestation and clinical signs compatible with ehrlichiosis hemorrhagic manifestations and thrombocytopenia.
