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.

Species, Sequence Types and Alleles: Dissecting Genetic Variation in Acanthamoeba

Pathogens, 2020
Species designations within Acanthamoeba are problematic because of pleomorphic morphology. Molecular approaches, including DNA sequencing, hinted at a resolution that has yet to be fully achieved. Alternative approaches were required. In 1996, the Byers/

Silver Nanoparticles as a Novel Potential Preventive Agent against Acanthamoeba Keratitis

Pathogens, 2020
Free living, cosmopolitan amoebae from Acanthamoeba genus present a serious risk to human health. As facultative human parasites, these amoebae may cause Acanthamoeba keratitis (AK).

Enhancing Acanthamoeba diagnostics: rapid detection of viable Acanthamoeba trophozoites and cysts using viability PCR assay

Microbiology Spectrum
Acanthamoeba keratitis (AK) is a sight-threatening corneal infection that is challenging to diagnose and treat due to the resistance of Acanthamoeba to standard antimicrobial agents. Current detection methods have limitations. This study aimed to develop
