Abstract: Background: Acanthamoeba is a genus of amoeba, one of the most common protozoa found worldwide in soil, and also frequently found in fresh water. In healthy individuals, Acanthamoeba spp. can cause ulcerating keratitis which is often associated with the use of improperly sterilized contact lenses. The aim of this study was to detect Acanthamoeba from fresh water collected from some t...

Abstract Background and Objective: Acanthamoeba species are free-living protozoa that can be isolated from all environments. They can bring about different diseases in healthy individuals and immune suppressed patients, for example, Granulomatous Amoebic Encephalitis (GAE), Acanthamoeba Keratitis (AK), Cutaneous and Nasopharyngeal infections. The aim of this study was to evaluate the Acanthamoe...

Background: Acanthamoeba is a free-living and opportunistic amoeba that the potential of this parasite to convert to a cyst, making its treatment difficult. In this study, we investigated the effect of microwave radiation on Acanthamoeba cysts in vitro. Materials and Methods: Acanthamoeba cysts were reproduced in the culture medium. We divided 16 test tubes containing cysts into two groups. Th...

Acanthamoeba keratitis is a vision-threatening infection caused by pathogenic species of the genus Acanthamoeba. Although not all Acanthamoeba spp. can cause keratitis, it is important to differentiate pathogenic species and isolates from nonpathogens. Since extracellular proteases may play a role in ocular pathology, we used colorimetric, cytopathic, and zymographic assays to assess extracellu...

Introduction & Objective: Acanthamoeba is free-living amoeba that is found in soil, water, air as well as in human pharynx. Acanthamoeba is causative agent of granulomatose amoebic encephalitis (GAE) in immunosuppressed and AIDS individuals and amoebic keratitis in people who use the lens. Pathogenic species of Acanthamoeba have protein receptors named mannose binding protein (MBP). Acanthamo...

Acanthamoeba is free-living protist pathogen capable of causing a blinding keratitis and granulomatous encephalitis. However, the mechanisms of Acanthamoeba pathogenesis are still not clear. Here, our results show that cells co-cultured with pathogenic Acanthamoeba would be spherical and floated, even without contacting the protists. Then, the Acanthamoeba protists would contact and engulf thes...

A new species of Acanthamoeba was isolated from a freshwater fish in Korea and tentatively named Acanthamoeba sp. YM-4 (Korean isolate YM-4). The trophozoites were 11.0-23.0 micrometer in length and had hyaline filamentous projections. Cysts were similar to those of A. culbertsoni and A. royreba, which were previously designated as Acanthamoeba group III. Acanthamoeba YM-4 can survive at 40 deg...

Background: The genus of Acanthamoeba is an opportunistic protozoan parasite with a worldwide distribution where it is able to cause fatal granulomatous amoebic encephalitis (GAE) and amoebic keratitis (AK). This organism inhabits in the wide range of natural and man-made aquatic environments. The present study was carried out to evaluate the presence of Acanthamoeba spp. in the various water r...

Background and purpose: Acanthamoeba species are ubiquitous amphizoic organisms which can cause lethal diseases, such as keratitis and encephalitis in domestic animals and humans. The first stage in studies related to Acanthamoeba is achieving abundant amount of amoebae in culture medium. The aim of this study was to evaluate TYM medium as a rich medium for the diagnosis of Acanthamoeba keratit...
