Free‐living, Amphizoic and Opportunistic Amebas
TL;DR: Amebas belonging to the genera Naegleria, Acanthamoeba and Balamuthia are free‐living, amphizoic and opportunistic protozoa that are ubiquitous in nature.

Pearl Ma,Govinda S. Visvesvara,A J Martinez,Frederick H. Theodore,Pierre-Marc Daggett,Thomas K. Sawyer +5 more
TL;DR: The recent increase in acanthamoeba keratitis (more than 200 cases), especially in contact lens wearers, has generated new interest in this group of amebas and risk factors, clinical manifestations, and laboratory parameters helpful in the recognition of infections of the central nervous system are reviewed.
Journal ArticleDOI
Balamuthia Mandrillaris, N. G., N. Sp., Agent of Amebic Meningoencephalitis In Humans and Other Animals
TL;DR: A new genus, Balamuthia, is created to accommodate the isolation of a leptomyxid ameba from the brain of a mandrill baboon that died of meningo‐encephalitis, and it is concluded that this isolate differs fundamentally from the other two amebas included in the Order Leptonomyxida.

Granulomatous amebic encephalitis: a review and report of a spontaneous case from Venezuela
A J Martinez,A J Martinez,Ana Elia Guerra,Jorge García-Tamayo,Ghislaine Céspedes,Jusús E. González-Alfonzo,Govinda S. Visvesvara +6 more
TL;DR: A case of GAE caused by Balamuthia mandrillaris previously designated as a leptomyxid ameba, in an apparently healthy 14-year-old Venezuelan boy is described, and it remains possible that an undiagnosed abnormality in cell-mediated immunity or a deficient humoral immune response may explain the susceptibility of this patient to this opportunistic infection.
