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.

First Report of Hartmannella keratitis in a Cosmetic Soft Contact Lens Wearer in Iran

Iranian Journal of Parasitology, 2013
Background: Poor hygiene will provide good condition for corneal infections by opportunistic free-living amoebae (FLA) in soft contact lens wearers. In the present study an amoebic keratitis due to Hartmannella has been recognized in a 22-year-old girl ...

Sensitivity of Vermamoeba (Hartmannella) vermiformis cysts to conventional disinfectants and protease [PDF]

Journal of Water and Health, 2014
Vermamoeba vermiformis is a free-living amoeba (FLA) widely distributed in the environment, known to colonize hot water networks and to be the reservoir of pathogenic bacteria such as Legionella pneumophila. FLA are partly resistant to biocides, especially in their cyst form. The control of V.

Prevalence and diversity of Chlamydiales and other amoeba-resisting bacteria in domestic drinking water systems. [PDF]

, 2016
A growing number of human infections incriminate environmental bacteria that have evolved virulent mechanisms to resist amoebae and use them as a replicative niche. These bacteria are designated amoeba-resisting bacteria (ARB).

The CRISPR-Associated Gene cas2 of Legionella pneumophila Is Required for Intracellular Infection of Amoebae

mBio, 2013
Recent studies have shown that the clustered regularly interspaced palindromic repeats (CRISPR) array and its associated (cas) genes can play a key role in bacterial immunity against phage and plasmids.

Sessile Legionella pneumophila is able to grow on surfaces and generate structured monospecies biofilms [PDF]

, 2010
Currently, models for studying Legionella pneumophila biofilm formation rely on multi-species biofilms with low reproducibility or on growth in rich medium, where planktonic growth is unavoidable.

Identification of new amoebae strains in rainbow trout (Oncorhynchus mykiss, Walbaum) farms affected by nodular gill disease (NGD) in Northeastern Italy

Journal of Fish Diseases, Volume 47, Issue 6, June 2024.
Abstract Nodular gill disease (NGD) is an emerging condition associated with amoeba trophozoites in freshwater salmonid farms. However, unambiguous identification of the pathogens still must be achieved. This study aimed to identify the amoeba species involved in periodic NGD outbreaks in two rainbow trout (Oncorhynchus mykiss) farms in Northeastern ...

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.
