Giardia lamblia Will Give You FATTY DIARRHEA

The Giardia trophozoite form kind of reminds me of the Sentinels in the Matrix. Kind of. Barely.

Protozoans! They're not bacteria, they're not viruses, and they're not fungi either. They're weird little organisms in Kingdom Protista, and they also cause a bunch of diseases.

Giardia lamblia is one of the coolest looking protozoans out there. These protozoans cause Giardiasis, which is characterized by greasy, foul-smelling stool and other GI disturbances. You get Giardiasis from drinking the cyst form in water. Mmm.

This is the trophozoite form of the organism that you can find in your stool if you happen to have Giardiasis. Treatment: Metronidazole, whose mechanism of action ultimately leads to the build-up of toxic metabolites.

Wikipedia also calls Giardiasis BEAVER FEVER?!
