Positive samples from dogs 7, 12, 17, 19, 23, and 25 are indicated by a bp band. Some inclusions were surrounded by a visible membrane, whereas others seemed to be in the cytoplasm of the platelet precursors without a membrane Fig. Thrombocytopenia in both animals was classified as regenerative on the basis of an appropriate bone marrow response, as observed by cytology. This variability in clinical symptoms of infection has not been clearly associated with strain variations 11 — Clin Diagn Lab Immunol ; 9: First evidence of Anaplasma platys in Rhipicephalus sanguineus Acari: After infection, there is an incubation period of several weeks followed by a period during which parasitemia increases rapidly and is quickly followed by precipitous drop in hematocrit.
