Infections Caused by Free-Living Amoebae

Journal of Clinical Microbiology, 2022
Infections caused by Naegleria fowleri , Acanthamoeba spp., and Balamuthia mandrillaris result in a variety of clinical manifestations in humans. These amoebae are found in water and soil worldwide. Acanthamoeba spp.

Sensitivity of free-living amoeba trophozoites and cysts to water disinfectants

International Journal of Hygiene and Environmental Health, 2014
International audienceFree-living amoebae are naturally present in water. These protozoa could be pathogenic and could also shelter pathogenic bacteria. Thus, they are described as a potential hazard for health.

Free-living amoebae as vectors of cryptosporidia

Parasitology Research, 2011
In the present article, the study to examine the ability of free-living amoebae (FLA) to serve as vectors of cryptosporidia is presented. Ten strains of different free-living amoebae of the FLA collection of the Parasitology Lab at Koblenz were cultivated in the presence of Cryptosporidium parvum oocysts.

Ecology of Free-Living Amoebae

Critical Reviews in Microbiology, 1994
Small free-living amoebae (FLA) are the main predators controlling bacterial populations in soils. They are distributed in the rhizospheric zone and the surrounding bulk soil; however, they may spread deeper, reaching the vadose zone of groundwater systems, especially where bacterial populations get to high densities.

Chemotaxis in large, free-living amoebae

Experimental Cell Research, 1965
Abstract Free-living large amoebae have been shown to exhibit directed chemotactic movement towards hydra tissue and a water-soluble fraction extracted from commercial crude papain. The chemotactic responses are produced by the local formation of pseudopods and their subsequent extension.

Bacterial infections of free-living amoebae

Research in Microbiology, 2001
Free-living amoebae are a diverse group of ubiquitous unicellular organisms, some of which cause severe central nervous system infections and keratitis. However, the focus of research has shifted from the direct pathogenic effects of free-living amoebae towards their role as carriers of pathogenic bacteria.

Epidemiology of Pathogenic Free-living Amoeba

International Journal of TROPICAL DISEASE & Health, 2022
Free-living amoeba (FLA) is a free living parasitic organism which have the capability to infect human and attack various vital organs e.q., the central nervous system, eyes, skin, nose, lungs and kidneys; depending on which organ is reached. When it comes to the central nervous system, this disease is very fatal and potentially lethal because the ...

Bacterial endosymbionts of free-living amoebae.

The Journal of eukaryotic microbiology, 2004
The occurrence of bacterial endosymbionts in free-living amoebae has been known for decades, but their obligate intracellular lifestyle hampered their identification. Application of the full cycle rRNA approach, including 16S rRNA gene sequencing and fluorescence in-situ hybridization with 16S rRNA-targeted oligonucleotide probes, assigned the ...
