Sappinia diploidea

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

Background[edit]

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[edit]

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

Symptoms of Sappinia Infection[edit]

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[edit]

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]
