Transmission occurs through ingestion of cysts in contaminated food or water.

The large intestine is the primary location for Entamoeba histolytica.

Parasites attach, secrete enzymes, invade tissues, damaging blood cells, and possibly spread to other organs.

Amoebic ulcers have a flask shape.

Entamoeba histolytica consumption of red blood cells results in tissue death.

Mobile, feeding forms that attach to the intestinal lining, releasing enzymes to break down tissue and invade underlying layers of the intestine.

Trophozoites attach using lectins and cause tissue destruction within the intestinal lining.

Trophozoites release protein-digesting enzymes and invade the underlying layers of the intestinal tissue.

Amoebas can be carried through the blood to other organs.

Amoebas in the bloodstream move to organs like the liver, brain, or heart, which can involve the presence of abscess or ulcers.

The trophozoite stage of a parasite has a size ranging from 15 to 50 µm.

The trophozoite stage is larger than the Leishmania stage.

No red blood cells (RBCs) are present inside trophozoites.

The trophozoite and cyst stages are present in this parasite, and are larger than those found in leishmania.

A unit of measurement for length, equal to one millionth of a meter for example, the size of microbes.

A parasitic amoeba causing amebiasis, a disease of human intestine.

Active, feeding stage of Entamoeba histolytica, found in feces.

Dormant, protective stage of Entamoeba histolytica, transmitted via ingest.

Trophozoites and cysts are the identifiable stages in stool specimens.

Trophozoite, precyst, cyst, and metacyst are the four stages in the Entamoeba life cycle.

Entamoeba histolytica cysts range from 10-33 µm in size.

A mature cyst contains 8 nuclei, similar to trophozoite nuclei.

Trophozoite nuclei have specific characteristics.

Mature cyst nuclei: have same properties as trophozoite nuclei

No red blood cells are present in the trophozoite stage.

The stage where the parasite is capable of causing infection, characterized by a cyst with four nuclei.

The stages of the parasite that are used to identify an infection in a sample.

The parasite is transmitted through the ingestion of cysts in contaminated food and water.

These stages are found inside the host's body, and they are part of the parasite's life cycle.

These are the stages of the parasite that can be observed in lab testing.
