Immature cysts like these can be easily confused with E. coli cysts which maybe the same size. Immature cysts may contain one or two nuclei as seen in these three cysts. A binucleate cyst containing a chromatoidal body is seen in this field. The small eccentric karyosome is not very evident. Note the characteristic nuclear structure of this amoeba.
Small vacuoles are present in the cytoplasm.
