Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes

Journal of Eukaryotic Microbiology, Volume 66, Issue 1, Page 4-119, January/February 2019., 2019
Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.

Isolation of Acanthamoeba isolates belonging to T2, T3, T4 and T7 genotypes from environmental samples in Ankara, Turkey [PDF]

, 2004
Acanthamoeba keratitis is a blinding infection that is becoming increasingly important in human health. Early diagnosis is a prerequisite for successful treatment and requires identification of Acanthamoeba at the genotypic level.

The Characterisation of an Adrenergic Signalling System Involved in the Encystment of the Ocular Pathogen Acanthamoeba spp. [PDF]

, 2016
The aim of this study was to identify and characterise the receptor system involved in controlling encystment in Acanthamoeba using specific agonists and antagonists and to examine whether endogenous stores of catecholamines are produced by the organism.

Structural characterization of the Sel1‐like repeat protein LceB from Legionella pneumophila

Protein Science, Volume 33, Issue 3, March 2024.
Abstract Legionella are freshwater Gram‐negative bacteria that in their normal environment infect protozoa. However, this adaptation also allows Legionella to infect human alveolar macrophages and cause pneumonia. Central to Legionella pathogenesis are more than 330 secreted effectors, of which there are nine core effectors that are conserved in all ...

Burkholderia pseudomallei Adaptation for Survival in Stressful Conditions

BioMed Research International, Volume 2018, Issue 1, 2018., 2018
Burkholderia pseudomallei is a Gram‐negative bacterium that causes melioidosis, which can be fatal in humans. Melioidosis is prevalent in the tropical regions of Southeast Asia and Northern Australia. Ecological data have shown that this bacterium can survive as a free‐living organism in environmental niches, such as soil and water, as well as a ...

Nonpathogenic Free-Living Amoebae in Arkansas Recreational Waters [PDF]

, 1975
Selected recreational waters of Arkansas were sampled for pathogenic free-living limax amoebae. Water quality parameters were determined for correlation with amoebic population densities and species diversity.

Grazing preferences of three species of amoebae on cyanobacteria and green algae

Journal of Eukaryotic Microbiology, Volume 71, Issue 2, March/April 2024.
Abstract Twenty species/isolates of cyanobacteria and green algae were isolated from cyanobacterial bloom samples in lakes associated with the upper Qu'Appelle River drainage system in southern Saskatchewan, Canada. Three amoebae species (Cochliopodium sp., Vannella sp.

Effect of temperature and colonization of Legionella pneumophila and Vermamoeba vermiformis on bacterial community composition of copper drinking water biofilms

Microbial Biotechnology, Volume 10, Issue 4, Page 773-788, July 2017., 2017
Summary It is unclear how the water‐based pathogen, Legionella pneumophila (Lp), and associated free‐living amoeba (FLA) hosts change or are changed by the microbial composition of drinking water (DW) biofilm communities. Thus, this study characterized the bacterial community structure over a 7‐month period within mature (> 600‐day‐old) copper DW ...

Identification of a Gal/GalNAc Lectin in the Protozoan Hartmannella vermiformis as a Potential Receptor for Attachment and Invasion by the Legionnaires' Disease Bacterium

Journal of Experimental Medicine, 1997
The Legionnaire's disease bacterium, Legionella pneumophila, is a facultative intracellular pathogen which invades and replicates within two evolutionarily distant hosts, free-living protozoa and mammalian cells.
