Escherichia coli, or E. Coli, is a species of bacteria. Entamoeba histolytica, or E. Histolytica, is a single-celled amoeba. What do E. Coli and E. Histolytica have in common?

They are single cell organisms.

They are both thophozites and intestinal amoebas.

Explanation:

Entamoeba histolytica

- A trophozoite of 20 to 40 µm and can reach 60 µm in invasive form;

- Has endo and ectocytoplasm;

- Usually a single core;

- Fresh: pleomorphic, active, elongated, with continued rapid emission of pseudopods;

- Pre-cyst, oval and slightly rounded and smaller than the trophozoite;

- Cyst from 8 to 20 µm in diameter;

- Metacyst, multinucleated where after divisions of origin to the trophozoite;

- Small cariosome and in the center of the nucleus.

Entamoeba coli

- Trophozoite from 20 to 50 µm;

- Undifferentiated cytoplasm in endo and ectocytoplasm;

- irregular and coarse chromatin core;

- Large and eccentric cariosome;

- Thin chromatoid bodies.
