The free living amoeba, Acanthamoeba spp are found and distributed in a wide variety of environmental sources including air, water, soil dust, vegetables as well as the skin, cornea, lung and brain of human (1). Isolation of Acanthamoeba cyst from environmental sources such as soil, fresh surface water and stagnant water have been showed that this environmental sources have potential importance...

Background and Aim: Vermamoeba vermiformis is an opportunistic free living amoeba(FLA) that is ubiquitous in different environmental sources. This Amoeba can cause Amoebic Keratitis(AK) and Granulomatous Amoebic Encephlitis (GAE) in immunocompromised patients. This study was conducted to determine the rate of Vermamoeba vermiformis in stagnant water and soil in Arak. Materials and Methods:  In...

Acanthamoeba- related infections, such as amoebic keratitis and granulomatous amoebic encephalitis, can develop in high-risk population through contaminated water sources. Thus, surveying water resources, particularly those available for human use, is of the utmost importance. In the present study, 67 water samples were collected from water resources in East Azerbaijan, a province in northweste...

background: acanthamoeba keratitis develops by pathogenic acanthamoeba such as a. pal­es­tinen­sis . indeed this species is one of the known causative agents of amoebic keratitis in iran. mannose binding protein (mbp) is the main pathogenicity factors for developing this sight threatening disease. we aimed to characterize mbp gene in pathogenic acanthamoeba isolates such as a. palestinensis . m...

conclusions the results of the present study revealed that soil resources of these areas were contaminated with opportunistic amoebas such as acanthamoeba and hartmannella spp. and this may lead to severe diseases in high-risk people, such as immunocompromised patients. background free-living amoebas are very abundant in nature, especially in water and soil. some species of amoebas cause seriou...

Acanthamoeba spp. are the causative agents of Acanthamoeba keratitis (AK), which mainly occurs in contact lens wearers, and of skin lesions, granulomatous amoebic encephalitis (GAE), and disseminating diseases in the immunocompromised host. AK therapy is complex and irritating for the eye, skin lesions are difficult to treat, and there is no effective treatment for GAE. Therefore, new anti-Acan...

Thiourea derivatives display a broad spectrum of applications in chemistry, various industries, medicines and various other fields. Recently, different thiourea derivatives have been synthesized and explored for their anti-microbial properties. In this study, four carbonyl thiourea derivatives were synthesized and characterized, and then further tested for their anti-amoebic properties on two p...

[b]Abstract Introduction[/b]. Among free-living amoebae that are widely distributed in nature only four genera/species are known as agents of human infections:[i] Acanthamoeba spp., Naegleriafowleri, Balamuthia mandrillaris[/i] and[i] Sappiniapedata[/i]. These amoebae are not well adapted to parasitism, and could exist in the human environment without the need for a host. Infections due to thes...
