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

Molecular Mimicry Between Epstein‐Barr Virus and Human Herpesvirus‐6 Proteins and Central Nervous System Proteins: Implications for T and B Cell Immunogenicity in an In Silico Study

Immunity, Inflammation and Disease, Volume 14, Issue 5, May 2026.
ABSTRACT Background The Epstein‐Barr virus (EBV) and human herpesvirus 6 (HHV‐6) are frequently linked to neuropsychiatric illnesses such as multiple sclerosis, depression, and chronic fatigue syndrome/myalgic encephalomyelitis. These viruses may induce autoimmune reactions by molecular mimicry, leading to damage to self‐epitopes in the central nervous

In Vitro Stability of the Biological Activity of Voriconazole against Acanthamoeba castellanii

Parasitologia, 2023
Acanthamoeba keratitis (AK) is a rare cornea disease caused by species of the Acanthamoeba genus. The antifungal voriconazole blocks the ergosterol synthesis in the protozoan membrane and is active against the cysts and trophozoites of Acanthamoeba spp ...

Effective targeting of pathogenic Acanthamoeba castellanii of the T4 genotype using nano-formulations of Quercetin [PDF]

The incidence of infections caused by pathogenic Acanthamoeba is increasing, yet the prognosis continues to be poor. Acanthamoeba spp. are responsible for causing a blinding keratitis and a fatal granulomatous amoebic encephalitis. Due to limited options

Quantitative proteomic analysis and functional characterization of Acanthamoeba castellanii exosome-like vesicles

Parasites & Vectors, 2019
Background Pathogenic protozoans use extracellular vesicles (EVs) for intercellular communication and host manipulation. Acanthamoeba castellanii is a free-living protozoan that may cause severe keratitis and fatal granulomatous encephalitis.

Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were
