Bacterial infections of free-living amoebae
Research in Microbiology, 2001Free-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, 2022Free-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 ...

Chemotaxis in large, free-living amoebae
Experimental Cell Research, 1965Abstract 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.

Ecology of Free-Living Amoebae
Critical Reviews in Microbiology, 1994Small 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.

Bacterial endosymbionts of free-living amoebae.
The Journal of eukaryotic microbiology, 2004The 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 ...

Free‐living amoebae: pathogenicity and immunity
Parasite Immunology, 1991Summary Free‐living amoebae cause three well‐defined disease entities: (i) primary amoebic meningoencephalitis. caused by Naegleria fowleri, (ii) granulomatous amoebic encephalitis and (iii) chronic amoebic keratitis, caused by species of Acanthamoeba.

Free-living amoebae as vectors of cryptosporidia
Parasitology Research, 2011In 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.

Vermamoeba vermiformis: a Free-Living Amoeba of Interest
Microbial Ecology, 2018Free-living amoebae are protists that are widely distributed in the environment including water, soil, and air. Although the amoebae of the genus Acanthamoeba are still the most studied, other species, such as Vermamoeba vermiformis (formerly Hartmannella vermiformis), are the subject of increased interest.

Polyamines biosynthesis and oxidation in free-living amoebae
Amino Acids, 2004In this paper we describe the polyamine biosynthesis and oxidation processes, giving an overview about recent results in free-living Amoebae. The protozoa polyamine levels are different in comparison with mammalian cells. Also, the polyamine levels in protozoa cells change if these species are pathological or not for the human beings.
