Sappinia diploidea is a free-living[1] amoeba species.
It usually occurs in elk and buffalo feces, places where farm animals are known to eat, soil containing rotting plants, and fresh water sources.
[3][4][5] Symptoms of a Sappinia infection include headache, photophobia, nausea or upset stomach, vomiting, blurred vision, and loss of consciousness.
[2] Treatment for the one identified case of Sappinia infection included the removal of a tumor in the brain and a series of drugs given to the patient after surgery.
This treatment led to the patient’s full recovery.
