Difference between cyst of e histolytica and giardia?

Cysts of Entamoeba histolytica and Giardia lamblia are both infectious forms of these protozoan parasites but differ in structure and disease association. E. histolytica cysts are typically smaller, have a thicker wall, and contain 1 to 4 nuclei, leading to amoebic dysentery and intestinal issues. In contrast, Giardia cysts are larger, oval-shaped, and contain 2 nuclei, primarily causing giardiasis, which results in gastrointestinal symptoms like diarrhea and abdominal discomfort. Both cysts are transmitted through contaminated water or food, but they target different host responses and tissues.
