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 ...

Inhibition by Theophylline of Phagocytosis in Acanthamoeba castellanii*
The Journal of Protozoology, 1976SYNOPSIS. Theophylline inhibited the phagocytosis of latex beads by Acanthamoeba castellanii (Neff). The cells recovered the ability to engulf beads after 1–2 hr of exposure to theophylline. Cells which have been exposed to 25 mM theophylline for a period of inhibition and recovery were not inhibited further by incubation with a fresh medium ...

Ribosomal Phosphoproteins in Acanthamoeba castellanii
European Journal of Biochemistry, 1981Ribosomes and subunits from Acanthamoeba castellanii were purified. The pattern of ribosomal proteins was analysed by two‐dimensional get electrophoresis. The small subunit of cytoplasmic ribosomes contains 25 and the large 40 proteins. After incubation of exponentially growing cells with ortho[33P]phosphate for 1 j, one basic protein of the small ...

Migration of Acanthamoeba castellanii Through Legionella Biofilms
2019The amoeba-resistant bacterium Legionella pneumophila infects humans through aerosols and thereby can cause a life-threatening pneumonia termed Legionnaires' disease. In the environment L. pneumophila forms and colonizes biofilms, which usually comprise complex multispecies communities. In these biofilms L.

Effect of Bacteria on Survival and Growth of Acanthamoeba castellanii
Current Microbiology, 1997The growth and survival of Acanthamoeba castellanii in the presence of Gram-negative bacteria such as Pseudomonas aeruginosa, Escherichia coli, Serratia marcescens, and Stenotrophomonas maltophilia varied with the densities and species of bacteria. All species of bacteria suspended in a buffered saline at densities of 10(5) to 10(6)/ml supported the ...

In vitro Characterization of Acanthamoeba castellanii Cytopathic Effect
The Journal of Parasitology, 1995This study examined the mechanism of the cytopathic effect (CPE) of Acanthamoeba castellanii on human target cells. Pathogenic Acanthamoeba trophozoites were incubated with human ocular melanoma (OCM1) cells for 30 min, 1 hr, and 3 hr. The amoebae were treated with a calcium ionophore (A23187), phorbol myristate ester (PMA), calcium channel blocker ...
