Biological characteristics and pathogenicity of Acanthamoeba

Frontiers in Microbiology, 2023
Acanthamoeba is an opportunistic protozoa, which exists widely in nature and is mainly distributed in soil and water. Acanthamoeba usually exists in two forms, trophozoites and cysts. The trophozoite stage is one of growth and reproduction while the cyst

Calcium ions in tap water may increase the adhesion ability of Acanthamoeba, potentially enhancing its cytopathic effects on corneal cells. [PDF]

Parasite
Acanthamoeba spp. are free-living amoebae found in various water sources, including domestic tap water. These amoebae are known to cause Acanthamoeba keratitis, a severe corneal infection that can lead to vision loss.

Detection of Acanthamoeba from Acanthamoeba Keratitis Mouse Model Using Acanthamoeba-Specific Antibodies

Microorganisms, 2022
Although the prevalence of Acanthamoeba keratitis (AK) is rare, its incidence in contact lens wearers has increased. Acanthamoeba infections can lead to the loss of vision if the diagnosis and treatment are delayed.

Contact lenses contamination by Acanthamoeba spp. in Upper Egypt.

PLoS ONE, 2021
BackgroundAcanthamoeba spp. are one of the free-living amoeba that spread worldwide causing keratitis. Owing to the increase in the use of lenses, whether for medical or cosmetic purposes, the incidence of disease increases every year.

Survey and first report of Acanthamoeba T4 genotype in natural spring water resources in the Black Sea, Turkey

Journal of Water and Health, 2022
Infection with Acanthamoeba spp. may result in granulomatous amoebic encephalitis and Acanthamoeba keratitis. Water is an important habitat where Acanthamoeba species thrive.

Acanthamoeba keratitis [PDF]

British Journal of Ophthalmology, 1994
We read with interest the report by Radford et al on the incidence of acanthamoeba keratitis and the suggested relation with hardness of water.1 However, we disagree with their findings and believe their study is flawed for two reasons. This paper discusses the flaws.

Acanthamoeba species isolated from marine water in Malaysia exhibit distinct genotypes and variable physiological properties

Journal of Water and Health, 2022
The present study identifies the Acanthamoeba genotypes and their pathogenic potential in five marine waters in Malaysia. Fifty water samples were collected between January and May 2019. Physical parameters of water quality were measured in situ, whereas

Pathogenic Acanthamoeba castellanii Secretes the Extracellular Aminopeptidase M20/M25/M40 Family Protein to Target Cells for Phagocytosis by Disruption

Molecules, 2017
Acanthamoeba is free-living protist pathogen capable of causing a blinding keratitis and granulomatous encephalitis. However, the mechanisms of Acanthamoeba pathogenesis are still not clear.

Acanthamoeba genotype T4 from the UK and Iran and isolation of the T2 genotype from clinical isolates [PDF]

, 2005
The majority of the keratitis-causing Acanthamoeba isolates are genotype T4. In an attempt to determine whether predominance of T4 isolates in Acanthamoeba keratitis is due to greater virulence or greater prevalence of this genotype, Acanthamoeba ...
