Sappinia diploidea

Sappinia diploidea is a free-living[1] amoeba species.[2]

Background

Sappinia can be found around the world. It's usually found in elk and buffalo feces, places where farm animals are known to eat, soil containing rotting plants, fresh water sources.,[3]

Clinical significance

It is capable of causing infectious disease in humans[4][5][6]

Symptoms of Sappinia Infection

Symptoms of a Sappinia infection include: Headache, Sensitivity to light, Nausea or upset stomach, Vomiting, Blurry vision, Loss of consciousness. A scan of the one, infected patient’s brain also revealed a 2-centimeter tumor-like mass on the back left section of his brain.[3]

Treatment

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 lead to the patient’s full recovery.[7]

Specifically, it can cause amebic encephalitis.[8][9]
