Giardia trophozoites stained with Giemsa; 100x magnification. G. duodenalis trophozoites are pear-shaped cells, 10 to 20 μm long, 7 to 10 μm across, and 2 to 4 μm thick. [14] [15] They are motile by way of four pairs of flagella, which propel the trophozoites through the intestine. [15]
Trophozoites are often found in the host's body fluids and tissues and in many cases, they are the form of the protozoan that causes disease in the host. [ 2 ] In the protozoan, Entamoeba histolytica it invades the intestinal mucosa of its host, causing dysentery, which aid in the trophozoites traveling to the liver and leading to the ...
