nuclei

Description:

Giardia (gee-arr-dee-a), a diplomonad flagellate that is a common inhabitant of the human intestine. These are diplomonads, they have two nuclei (anterior), and two sets with four flagella each arising from the front end of the cell but extending to the side or posteriorly. Normally they clamp onto cells of the intestine, and heavy infections can lead to cells being ripped from the gut wall leading to bloody diarrhoea. Phase contrast.
