Purine salvage by Acanthamoeba castellanii
International Journal for Parasitology, 1987Abstract Trophozoites of Acanthamoeba castellanii were found to incorporate a range of purine bases and nucleosides into parasite nucleic acids. Results from competition studies suggest that A. castellanii is capable of interconverting purine nucleotides.

Carbohydrate analysis of Acanthamoeba castellanii
Experimental Parasitology, 2009We analyzed biochemically Acanthamoeba castellanii trophozoites, intact cysts and cyst walls belonging to the T4 genotype using gas chromatography combined with mass spectrometry. Cyst walls were prepared by removing intracellular material from cysts by pre-treating them with sodium dodecyl sulphate (SDS) containing dithiothreitol, and then subjecting ...

Elucidation of iron homeostasis in Acanthamoeba castellanii
International Journal for Parasitology, 2022Acanthamoeba castellanii is a ubiquitously distributed amoeba that can be found in soil, dust, natural and tap water, air conditioners, hospitals, contact lenses and other environments. It is an amphizoic organism that can cause granulomatous amoebic encephalitis, an infrequent fatal disease of the central nervous system, and amoebic keratitis, a ...

Acanthamoeba castellanii cysts: new ultrastructural findings
Parasitology Research, 2013During Acanthamoeba castellanii trophozoite-cysts differentiation, four morphological stages were identified by scanning electron microscopy: trophozoite, precyst, immature cysts, and mature cysts. Fluorescence microscopy reveals the presence of small cumulus of actin in the cytoplasm of precysts after treatment with rhodamine phalloidin.

Glucolipid Synthesis in Acanthamoeba castellanii*
The Journal of Protozoology, 1976SYNOPSIS. Cell‐free preparations of Acanthamoeba castellanii trophozoites transfer glucose from UDP‐[U‐14C]glucose to a chloroform‐soluble form. This radioactive material has been isolated by thin‐layer chromatography; it contains an alkali‐labile and an alkali‐stable (unsaponifiable) component.

Protease activities of Acanthamoeba polyphaga and Acanthamoeba castellanii
Canadian Journal of Microbiology, 2006Acanthamoeba spp. are free-living amoebae that cause amoebic granulomatous encephalitis, skin lesions, and ocular amoebic keratitis in humans. Several authors have suggested that proteases could play a role in the pathogenesis of these diseases. In the present work, we performed a partial biochemical characterization of proteases in crude extracts of ...

Acanthamoeba castellanii: Cellular changes induced by chlorination
Experimental Parasitology, 2010Chlorination is a well-known disinfection method, used in water treatment to inactivate various microorganisms, it induces numerous cellular changes. Even though Acanthamoebae are frequently found in water, the cellular changes induced in Acanthamoebae have not been described in the literature.

Legionella pneumophila decreases velocity of Acanthamoeba castellanii
Experimental Parasitology, 2017Acanthamoeba castellanii is a free-living amoeba commonly found in aquatic environment. It feeds on bacteria even if some bacteria resist amoebal digestion. Thus, A. castellanii is described as a Trojan horse able to harbor pathogenic bacteria. L. pneumophila is one of the amoeba-resisting bacteria able to avoid host degradation by phagocytosis and to ...
