In Vitro Effectiveness of Soft Contact Lens Solutions Available on the Dutch Market against Acanthamoeba Species

Pathogens, 2023
Acanthamoeba keratitis is almost universally associated with contact lens (CL) use. Until today, however, CL solution manufacturing protocols lack testing of anti-amoebic activity.

Effects of Mannose on Pathogenesis of Acanthamoeba castellanii

The Korean Journal of Parasitology, 2012
Acanthamoeba spp. are single-celled protozoan organisms that are widely distributed in the environment. In this study, to understand functional roles of a mannose-binding protein (MBP), Acanthamoeba castellanii was treated with methyl-alpha-D-mannopyranoside (mannose), and adhesion and cytotoxicity of the amoeba were analyzed.

Acanthamoeba castellanii, a Predator of Cyanobacteria [PDF]

Microbiology, 1981
Acanthamoeba castellanii was isolated from soil and water as a predator of cyanobacteria. Several strains of A. castellanii consumed cyanobacteria but there were differences in predatory activity between strains. The unicellular Gloeocapsa alpicola and filamentous Anabaena flos-aquae were particularly susceptible to predation.

A Nutrient‐Responsive LuxR Regulator Orchestrates Effector Gene Expression Across the Legionella Genus

Molecular Microbiology, EarlyView.
LexR1 is a LuxR‐type regulator that links nutrient sensing to effector gene expression in Legionella. Activated by a casamino acid‐derived ligand, LexR1 directly controls multiple effector genes using a conserved regulatory element present in numerous putative effectors across different Legionella species.

A Phylogenomic Study of Acanthamoeba polyphaga Draft Genome Sequences Suggests Genetic Exchanges With Giant Viruses

Frontiers in Microbiology, 2018
Acanthamoeba are ubiquitous phagocytes predominant in soil and water which can ingest many microbes. Giant viruses of amoebae are listed among the Acanthamoeba-resisting microorganisms.

Development of a Machine Learning-Based Cysticidal Assay and Identification of an Amebicidal and Cysticidal Marine Microbial Metabolite against Acanthamoeba

Microbiology Spectrum, 2022
Traditional cysticidal assays for Acanthamoeba species revolve around treating cysts with compounds and manually observing the culture for evidence of excystation. This method is time-consuming, labor-intensive, and low throughput. We adapted and trained

Survival of taylorellae in the environmental amoeba Acanthamoeba castellanii [PDF]

BMC Microbiology, 2014
Taylorella equigenitalis is the causative agent of contagious equine metritis, a sexually-transmitted infection of Equidae characterised in infected mares by abundant mucopurulent vaginal discharge and a variable degree of vaginitis, cervicitis or endometritis, usually resulting in temporary infertility.

Soil Microbiome Predator Diversity Outperforms Nitrogen Addition in Boosting Plant Biomass via Bacterial Community Shifts

Global Change Biology, Volume 32, Issue 8, August 2026.
Soil biodiversity may help reduce dependence on nitrogen fertilization, but experimental evidence remains limited. We tested how microbiome predator diversity (protists and nematodes) and nitrogen addition influence Cannabis sativa performance. Increasing microbiome predator diversity enhanced plant biomass by up to 60%, exceeding the effects of ...
