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

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.

The relationship between environmental sources and the susceptibility of Acanthamoeba keratitis in the United Kingdom

PLoS ONE, 2020
Purpose To determine whether Acanthamoeba keratitis (AK) patients have higher rates of Acanthamoeba and free-living amoeba (FLA) colonising domestic sinks than control contact lens (CL) wearers, and whether these isolates are genetically similar to the ...

Midterm results after allogeneic simple limbal epithelial transplantation from deceased‐donor eyes in patients with persistent corneal epithelial defects due to limbal stem cell deficiency

Acta Ophthalmologica, Volume 103, Issue 2, Page e125-e135, March 2025.
Abstract Background This study aims to characterize the clinical outcomes after allogeneic simple limbal epithelial transplantation (alloSLET) utilizing tissue from cadaveric donor eyes to address persistent corneal epithelial defects caused by limbal stem cell deficiency.

Non-Contact-Lens-Related Acanthamoeba Keratitis Caused by Acanthamoeba sp. Group T4D/T4e

Parasitologia
Acanthamoeba keratitis (AK) is a rare but serious infection of the cornea, typically associated with contact lens wear. Here, we present a case of AK caused by the Acanthamoeba genotype T4D/T4e in a patient without identifiable risk factors: a 34-year ...

Isolation of Acanthamoeba Species and Bacterial Symbiont Variability in Puna Salt Plains, Argentina

Environmental Microbiology Reports, Volume 17, Issue 1, February 2025.
Acanthamoeba isolated from the extreme environments of the Puna salt plains in Argentina contain unique intracellular microbial communities that are distinct from those found in the surrounding environments. The number of shared taxa amongst intracellular amoebae across all sites was greater than the number of shared taxa between the amoebae and their ...

Acanthamoeba keratitis: confirmation of the UK outbreak and a prospective case-control study identifying contributing risk factors

British Journal of Ophthalmology, 2018
Background/aims Acanthamoeba keratitis (AK) is a chronic debilitating corneal infection principally affecting contact lens (CL) users. Studies were designed to test claims that the UK incidence may have increased in 2012–2014 and to evaluate potential ...

[Acanthamoeba keratitis].

Nederlands tijdschrift voor geneeskunde, 1996
Three patients, women aged 69, 25 and 30 years, with refractory keratitis were found to have a rare infection with Acanthamoeba. All wore soft contact lenses. The frequency of Acanthamoeba keratitis increased in recent years. At present, an efficacious antiprotozoal therapy is available, for instance in the form of polyhexamethylene biguanide and ...
