What antibiotics treat Giardia?

These include the Chlamydiaceae, Legionella and the Mycoplasmataceae (including mycoplasma and ureaplasma); the Rickettsiaceae are also often considered atypical.

Which is Gram-negative bacteria?

What type of parasite is Giardia lamblia?

Giardia lamblia (syn. Giardia intestinalis, Giardia duodenalis) is a flagellated unicellular eukaryotic microorganism that commonly causes diarrheal disease throughout the world.

Is Giardia a fungi?

Giardia intestinalis is a flagellate protozoan that has a simple life cycle that is composed of two stages: the trophozoite stage and the cyst stage (infective form).

What supergroup does Giardia lamblia belong to?

supergroup ExcavataGiardia lamblia is an intestinal parasitic protist that causes significant acute and chronic diarrheal disease worldwide. Giardia belongs to the diplomonads, a group of protists in the supergroup Excavata. Diplomonads are characterized by eight motile flagella organized into four bilaterally symmetric pairs.
