Sappinia is a genus of Amoebozoa.[1][2][3]Sappinia is a free-living amoeba (a single-celled organism), found in the environment. There are two known species of Sappinia: Sappinia diploidea and Sappinia pedata. This amoeba causes amoebic encephalitis, an infection of the brain. This infection is similar to those caused by other free-living amoebas, such as Naegleria fowleri, Balamuthia mandrillaris, and Acanthamoeba.

Only one case of amoebic encephalitis due to Sappinia infection has been reported worldwide. In 1998, a healthy 38-year-old man from Texas was diagnosed with an infection caused by Sappinia diploidea. Recently, however, this infection was recognized as being caused by Sappinia pedata. Although the patient was hospitalized, he survived without any long-term consequences.[4]
