Identification and genotyping of Acanthamoeba spp. in the water resources of western Iran

Parasite Epidemiology and Control, 2023
Background: Acanthamoeba spp. is opportunistic amoeba that resides in water, soil, and air. Some pathogenic genotypes of the genus of Acanthamoeba can cause granulomatous amoebic encephalitis (GAE) in people with a defective immune system.

Emergent Calabi-Yau Geometry [PDF]

, 2009
We show how the smooth geometry of Calabi-Yau manifolds emerges from the thermodynamic limit of the statistical mechanical model of crystal melting defined in our previous paper arXiv:0811.2801.

Environmental Mycobacterium avium subsp. paratuberculosis Hosted by Free-Living Amoebae

Frontiers in Cellular and Infection Microbiology, 2018
Mycobacterium avium subsp. paratuberculosis is responsible for paratuberculosis in animals. This disease, leading to an inflammation of the gastrointestinal tract, has a high impact on animal health and an important economic burden.

Discrimination, Crypticity, and Incipient Taxa in Entamoeba [PDF]

, 2012
Persistent difficulties in resolving clear lineages in diverging populations of prokaryotes or unicellular eukaryotes (protistan polyphyletic groups) are challenging the classical species concept.

Naegleria genus pangenome reveals new structural and functional insights into the versatility of these free-living amoebae

Frontiers in Microbiology, 2023
IntroductionFree-living amoebae of the Naegleria genus belong to the major protist clade Heterolobosea and are ubiquitously distributed in soil and freshwater habitats. Of the 47 Naegleria species described, N. fowleri is the only one being pathogenic to humans, causing a rare but fulminant primary amoebic meningoencephalitis.

Dimer geometry, amoebae and a vortex dimer model [PDF]

, 2016
We present a geometrical approach for studying dimers. We introduce a connection for dimer problems on bipartite and non-bipartite graphs. In the bipartite case the connection is flat but has non-trivial ${\bf Z}_2$ holonomy round certain curves.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, EarlyView.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Encystment Induces Down-Regulation of an Acetyltransferase-Like Gene in Acanthamoeba castellanii

Pathogens, 2020
Acanthamoeba castellanii is a ubiquitous free-living amoeba. Pathogenic strains are causative agents of Acanthamoeba keratitis and granulomatous amoebic encephalitis. In response to adverse conditions, A.

Saline-Tolerant Pathogenic Acanthamoeba spp. Isolated from a Geothermal Power Plant

Pathogens, 2023
Few studies have been conducted in the cooling systems of power plants; they have focused on Naegleria fowleri, leaving a gap in the knowledge of other pathogenic free-living amoebae in this environment.

Impact on Plankton Communities Following Abandonment of Rice Cultivation and Biotope Creation. [PDF]

Ecol Evol
This study clarified changes in plankton communities during the first year of fallow in long‐term cultivated paddy fields in Kyoto. These fields were in a fallow state, with no planting, cultivation, or fertilization occurring. When water was introduced at the same time of year as during active use and the fields were converted into biotopes, diversity
