To Avner: >Do the follwing desises occur in ferrets ? > >Ehrlichiosis >Henobartonella Haven't even seen nor heard of these problems in ferrets, or other mustelids. Both of these conditions are parasites of the cells of the blood in dogs, cats, ad several other species. Ehrlichia parasitizes white blood cells and platelets, and Hemobartonella parasitizes red blood cells. But not in ferrets.
