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.

Free-Living Amoebae in Southeast Asia
2013In Southeast Asia (SEA), human infections caused by free-living amoebae (FLA) such as species of Acanthamoeba, Naegleria, Balamuthia, Vahlkampfia and Hartmannella were occasionally reported. To date, human cases or research work on these FLA have only been detected or performed in five countries which were Thailand, Malaysia, Singapore, Vietnam and the

Aerobic small free-living amoebae
1975It has been generally postulated that primary amoebic meningoencephalitis in man caused by the free-living amoeba, Naegleria aerobia (see chapters 3 and 4), is due to the entry of trophozoites through the intranasal route during swimming or bathing in fresh water.

[Cultivation of pathogenic free-living amoebae].
Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2010The isolation and culture of pathogenic free-living amoebae are useful in the diagnosis and research. This review focuses on the methods of isolation and cultivation of pathogenic free-living amoebae, including sample treatment, culture conditions, passage culture, pathogen detection, and maintenance.
