Sappinia

Sappinia is a genus of amoebae, belonging to the family Thecamoebidae. It is known for its rare ability to cause disease in humans, specifically a brain infection known as amoebic encephalitis.

Overview

The genus Sappinia was first described in 1899 by F. Doflein, a German zoologist. The name Sappinia is derived from the Greek word "sappinus", meaning soap, due to the soap-like appearance of the amoebae. The genus currently includes two recognized species: Sappinia diploidea and Sappinia pedata.

Characteristics

Sappinia amoebae are typically found in soil and fresh water environments. They are characterized by their unique shell-like structure, known as a test, which is composed of organic material and mineral particles. The test is typically oval in shape and has a single opening, or pseudostome, through which the amoeba extends its pseudopodia for movement and feeding.

Pathogenicity

While Sappinia is generally considered a free-living amoeba, there have been rare cases of Sappinia causing disease in humans. The most notable case involved a patient who developed amoebic encephalitis after exposure to Sappinia diploidea. This is the only known case of Sappinia causing disease in humans.

Treatment

Treatment for Sappinia infections typically involves a combination of antifungal and antiprotozoal medications. However, due to the rarity of Sappinia infections, there is limited data on the effectiveness of these treatments.
