This week's case is generously donated by Dr. Rasool Jafari from the Department of Parasitology and Mycology, School of Medicine, Urmia University of Medical Sciences, Urmia, Iran. These objects were isolated from a patient and cultured in Modified TYI-S-33 medium. What parasite is this, and what are we seeing here?

Giardia lamblia trophozoites
Yes, G lamblia. Typical “falling leaf” motion.
My first thought of a culture is Trichomonas vaginalis, but the shape is pyriform with a convex upper side and a concave underside tells me otherwise. The flipping as well as lateral sliding motion like a leaf leads me to Giardia lamblia. It’s not my first encounter with live Giardia lamblia trophozoites but it’s the first time I learned that the organism can be cultured.
It’s so exciting, check the timing of the answers. They only differ by minutes, how passionate parasitologists can be. Idzi must be in bed by now otherwise we would have his response as well.
Haha… you’re right Florida Fan!
Just woke up! 🤣
Beautiful video material of Giardia trophozoites! Note that it’s official name now is “Giardia duodenalis”.
We used to cultivate these critters on Keisters medium for educational purposes. Not easy though, so the more impressing this video by Dr. Rasool Jafari is! Kudos!
It's wonderful. Thank you very much for uploading
Wonderful this motion ! I've never seen before. Thank You very much!
Had exactly the same thought!
Giardia... Beautifully captured
Giardia trophozoites. I usually don't get to see them alive and in motion.
