Regeneration of test in testate amoebae of the genus Arcella (Tubulinea, Arcellinida)
European Journal of Protistology, 2016Although the presence of test is the most fundamental synapomorphy of arcellinid lobose amoebae, the significance of tests in maintenance of the biological functions of these organisms is still largely unclear. This paper demonstrates the effect of the artificial test removal on the behaviour, ultrastructure and reproduction of the testate lobose ...

Therapeutic agents and biocides for ocular infections by free-living amoebae of Acanthamoeba genus
Survey of Ophthalmology, 2017Acanthamoeba keratitis is a sight-threatening infectious disease. Resistance of the cystic form of the protozoan to biocides and the potential toxicity of chemical compounds to corneal cells are the main concerns related to long-term treatment with the clinically available ophthalmic drugs. Currently, a limited number of recognized antimicrobial agents

Ptolemeba n. gen., a Novel Genus of Hartmannellid Amoebae (Tubulinea, Amoebozoa); with an Emphasis on the Taxonomy of Saccamoeba [PDF]
AbstractHartmannellid amoebae are an unnatural assemblage of amoeboid organisms that are morphologically difficult to discern from one another. In molecular phylogenetic trees of the nuclear‐encoded small subunit rDNA, they occupy at least five lineages within Tubulinea, a well‐supported clade in Amoebozoa. The polyphyletic nature of the hartmannellids

[Isolation and identification of an amoeba of the genus Naegleria].
One pathogenic free-living amoeba, strain W042302 (Fig. 1.), was first isolated from the cooling water of a power plant in Shanghai, in April, 1986. It could result in the deaths of mice, and recovered from the brain tissue of the dead mice. This pathogenic free living amoeba could be induced into trophozoite with two flagellae (Fig. 2.).

The genus KorotnevellaGoodkov, 1988 (Amoebozoa: Dactylopodida) comprises amoebae with a complex cell coat that include a layer of scales covering the entire cell surface. Until now no Korotnevella species were known to form cysts. Here we describe two new species of genus Korotnevella and provide a light- and electron-microscopic report of encystment ...
