Commensals Serve as Natural Barriers to Mammalian Cells during Acanthamoeba castellanii Invasion

Microbiology Spectrum, 2021
Acanthamoeba castellanii is a free-living, pathogenic ameba found in the soil and water. It invades the body through ulcerated skin, the nasal passages, and eyes and can cause blinding keratitis and granulomatous encephalitis.

Pathogenic strains of Acanthamoeba are recognized by TLR4 and initiated inflammatory responses in the cornea. [PDF]

PLoS ONE, 2014
Free-living amoebae of the Acanthamoeba species are the causative agent of Acanthamoeba keratitis (AK), a sight-threatening corneal infection that causes severe pain and a characteristic ring-shaped corneal infiltrate.

Acanthamoeba castellanii Can Facilitate Plasmid Transfer Between Environmental Pseudomonas spp. [PDF]

J Basic Microbiol
ABSTRACT The conditions in which antimicrobial resistance (AMR) genes are transferred in natural environments are poorly understood. Acanthamoeba castellanii (a cosmopolitan environmental amoeba) feeds on bacteria by phagocytosis, which places the consumed bacteria closely together in a food vacuole (phagosome) of the amoeba.

Metronidazole conjugated magnetic nanoparticles loaded with amphotericin B exhibited potent effects against pathogenic Acanthamoeba castellanii belonging to the T4 genotype

AMB Express, 2020
Acanthamoeba castellanii can cause granulomatous amoebic encephalitis and Acanthamoeba keratitis. Currently, no single drug has been developed to effectively treat infections caused by Acanthamoeba.

The Anti-Amoebic Activity of a Peptidomimetic against Acanthamoeba castellanii

Microorganisms, 2022
Acanthamoeba is a free-living protozoan known to cause keratitis most commonly, especially among contact lens wearers. Treatment of Acanthamoeba keratitis is challenging as Acanthamoeba can encyst from the active form, a trophozoite, into a hibernating ...

Transcriptional changes of proteins of the thioredoxin and glutathione systems in Acanthamoeba spp. under oxidative stress – an RNA approach

Parasite, 2022
The thioredoxin (Trx) and the glutathione (GSH) systems represent important antioxidant systems in cells and in particular thioredoxin reductase (TrxR) has been shown to constitute a promising drug target in parasites.

Chemiluminescence of Acanthamoeba castellanii [PDF]

Biochemical Journal, 1979
1. Chemiluminescence of Acanthomoeba castellanii in the presence of O2 was of similar intensity in organisms harvested early or late during exponential growth [when cyanide (1 mM) stimulates or inhibits respiration respectively]. 2. Cyanide (up to 1.5 mM) stimulated photoemission in both types of organism by 250–300 photons/s per 10(7) cells above the ...
