The first case of
Entamoeba of the 1-nucleate mature cyst group in birds is described. Trophozoites and cysts of
Entamoeba have been found in ostriches (
Struthio camelus) from farms located all over Spain. The cysts are large (13.47
μm mean diameter); they possess one nucleus when mature, with a large endosome and peripheral chromatine arranged in small granules; chromatoid bodies, when present, are large and elongated. Trophozoites are large (19.88
μm mean diameter), with a clear differentiation between ecto- and endoplasm, this containing numerous vacuoles; the nucleus is large and diffuse. The characteristics of this amoeba resembles but do not completely fulfill those of
E. suis and
E. chattoni; also, these species are from mammals.
