Pathogenic Free-living Amoeba
These are Acanthamoeba spp., Balamuthia mandrillaris (the only known species of Balamuthia), Naegleria fowleri (sometimes considered not to be an amoeba at all, but more closely related to Leishmania and Trypanosoma) and Sappinia pedata. They are distinct from the more famous Entamoeba histolytica (an obligate anaerobic parasite which can cause amoebiasis, amoebic dysentery and amoebic liver ab...
متن کاملDetection of Potentially Pathogenic Free-living Amoeba, from the Internal Environment of Educational Hospitals in Rasht
Introduction: Acanthamoeba, also called amphizoic amoebae, could live in various environmental sources including water, soil, dust and also human and animal tissues. This amoeba could develop diseases such as keratitis and encephalitis in high-risk individuals. Objective: The present study was conducted considering the possible contamination of hospital wards with Acanthamoba and the lack of...
متن کاملApoptosis as a mechanism of cytolysis of tumor cells by a pathogenic free-living amoeba.
Previous studies have shown that trophozoites of the pathogenic free-living amoeba Acanthamoeba castellanii rapidly lysed a variety of tumor cells in vitro. Tumor cells undergoing parasite-mediated lysis displayed characteristic cell membrane blebbing reminiscent of apoptosis. The present investigation examined the role of apoptosis (programmed cell death) in Acanthamoeba-mediated tumor cell ly...
متن کاملIn vitro and in vivo tumoricidal properties of a pathogenic/free-living amoeba.
The chemotactic and tumoricidal properties of the pathogenic/free-living amoeba Acanthamoeba castellanii were examined in vivo and in vitro. A. castellanii trophozoites displayed strong positive chemotactic responses to human melanoma (OCM-1) and murine melanoma (D5.1G4) cells. Although the parasites typically invade and destroy the corneal epithelium and stroma, positive chemotactic responses ...
متن کاملThe role of free-living pathogenic amoeba in the transmission of leprosy: a proof of principle.
OBJECTIVES Leprosy transmission remains poorly understood, though, prolonged skin contact and/or infection via nasal mucosa, are considered likely. Problematic in any transmission hypothesis is the fastidious nature of Mycobacterium leprae outside its host cell and the requirement for temporary survival in the environment, soil or water. Experiments were carried out to test the hypothesis that ...
