NIH Rare Diseases : ⁵⁴ Granulomatous amebic encephalitis is a life-threatening infection of the brain caused by the free-living amoebae Acanthamoeba spp., Balamuthia mandrillaris and Sappinia pedata. Acanthamoeba species, are commonly found in lakes, swimming pools, tap water, and heating and air conditioning units. The disease affects immunocompromised peple and is very serious. Symptoms include mental status changes, loss of coordination, fever, muscular weakness or partial paralysis affecting one side of the body, double vision, sensitivity to light and other neurologic problems. The diagnosis is difficult and is often made at advanced stages. Tests useful in the diagnosis include brain scans, biopsies, or spinal taps and in disseminated disease, biopsy of the involved sites and testing by the laboratory experts. Early diagnosis is important for the prognosis. No single drug is effective; hence multiple antibiotics are needed for successful treatment. A combination of surgical and medical interventions involving multiple specialty experts is required to prevent death and morbidity in survivors.

MalaCards based summary : Granulomatous Amebic Encephalitis, also known as granulomatous amebic encephalitis due to acanthamoeba, is related to amoebiasis due to free-living amoebae and encephalitis. An important gene associated with Granulomatous Amebic Encephalitis is GMPPB (GDP-Mannose Pyrophosphorylase B), and among its related pathways/superpathways are One carbon pool by folate and Renin secretion. Affiliated tissues include brain, skin and lung.

Disease Ontology : ¹² A parasitic protozoa infectious disease that results in infection of the brain caused by Acanthamoeba or Balamuthia mandrillaris. The symptoms include headaches, altered mental status, and focal neurologic deficit, which progresses over several weeks to death.

CDC : ³ Acanthamoeba is a microscopic, free-living ameba, or amoeba* (single-celled living organism), that can cause rare**, but severe infections of the eye, skin, and central nervous system. The ameba is found worldwide in the environment in water and soil. The ameba can be spread to the eyes through contact lens use, cuts, or skin wounds or by being inhaled into the lungs. Most people will be exposed to Acanthamoeba during their lifetime, but very few will become sick from this exposure. The three diseases caused by Acanthamoeba are:
