Granulomatous Amoebic Encephalitis Caused by Acanthamoeba Amoebae of Genotype T2 in a Human Immunodeficiency Virus-Negative Patient [PDF]

Journal of Clinical Microbiology, 2008
ABSTRACT Acanthamoeba amoebae of genotype T2 were identified as the causative agent of Acanthamoeba skin lesions and granulomatous amoebic encephalitis (GAE) in a human immunodeficiency virus-negative patient with underlying tuberculosis.

Acanthamoeba castellanii induces host cell death via a phosphatidylinositol 3-kinase-dependent mechanism

, 2005
Granulomatous amoebic encephalitis due to Acanthamoeba castellanii is a serious human infection with fatal consequences, but it is not clear how the circulating amoebae interact with the blood-brain barrier and transmigrate into the central nervous ...

Non-granulomatous cerebellar infection by Acanthamoeba spp. in an immunocompetent host [PDF]

, 2018
Acanthamoeba spp. is a free-living amoeba, frequently involved in keratitis by contact lens in immunocompetent hosts. Anecdotal reports associate Acanthamoeba spp. as a cause of severe granulomatous encephalitis in immunocompromised and, less frequently,

Amebicidal and Antiadhesion Activities of Knema retusa Extract Against Acanthamoeba triangularis T4 Genotype on Contact Lenses and Modeling Simulation of Its Main Compound, E2N, Against Acanthamoeba Beta‐Tubulin

Scientifica, Volume 2025, Issue 1, 2025.
Medicinal plants have been used as alternative agents for the treatment of infections. This study aimed to investigate bioactivities of medicinal plant extracts including Knema retusa extract (Kre) against Acanthamoeba triangularis T4 in vitro and in silico. Anti‐Acanthamoeba activities of 44 extracts from 5 plant species were determined.

Amoebicidal activity of cationic carbosilane dendrons derived with 4-phenylbutyric acid against Acanthamoeba griffini and Acanthamoeba polyphaga trophozoites and cysts

Scientific Reports, 2022
Amoebae from the genus Acanthamoeba are important pathogens responsible for severe illnesses in humans such as Acanthamoeba keratitis and granulomatous amoebic encephalitis. In the last few decades, AK diagnoses have steadily increased.

Modelling dynamics between free‐living amoebae and bacteria

Environmental Microbiology, Volume 26, Issue 5, May 2024.
This review scrutinizes mathematical models designed to simulate the interactions between free‐living amoebae and bacteria. Identified gaps encompass (1) the necessity to tackle complexities such as spatial heterogeneity and population diversity; and (2) the essential understanding of the system.

Granulomatous amoebic encephalitis caused by Balamuthia mandrillaris.

Neurologia medico-chirurgica, 2013
A 51-year-old immunocompetent Japanese woman presented with a rare case of granulomatous amoebic encephalitis (GAE) caused by Balamuthia mandrillaris. She was brought to our hospital with epilepsy. Magnetic resonance imaging of the brain revealed a homogeneously enhanced solitary mass in the left frontal lobe.

Occurrence of small free-living amoebae from natural water resources

Environment Conservation Journal, 2009
Small  free-living amoebae are also  called  as amphizoic amoebae,  because of their capability to exist both  as free-living  as well  as opportunistically  pathogenic.

Glucose metabolism in the pathogenic free‐living amoebae: Tempting targets for treatment development

Chemical Biology &Drug Design, Volume 103, Issue 1, January 2024.
Enzymes involved in glucose metabolism may be promising therapeutic targets for drug development against the pathogenic free‐living amoebae. Details about the enzyme sequence and structural properties make a compelling case for designing small molecule inhibitors that are specific to the amoebae and would not affect the host enzyme.AbstractPathogenic ...

Human infections caused by free-living amoebae

Annals of Agricultural and Environmental Medicine, 2017
Introduction Among free-living amoebae that are widely distributed in nature only four genera/species are known as agents of human infections: Acanthamoeba spp., Naegleriafowleri, Balamuthia mandrillaris and Sappiniapedata.
