          We are a diagnostic Veterinary Laboratory. We are receiving
          increased numbers of Emu and Ostrich specimens. Recently we
          received feces from a 11 month old Ostrich. This bird has lost
          weight in the two months the owner has had it. Out of 20 in a
          group, three are losing weight and are less than a year old. We
          performed a ZnSO4 flotation and found many round amoeba
          cysts.(Two sizes: one was approx. 15x15u and the other approx.
          8.5x8.5u). Also we saw a few ova that were oval, no pigment, and
          measure approx. 42ux68u.  Is there an amoeba (Entamoeba?) that
          may cause intestional disease? Does anyone have an idea what the
          other ova be?
