Acanthamoeba species are free-living amoebae that can be found in almost every range of environments. Within this genus, a number of species are recognized as human pathogens, potentially causing Acanthamoeba keratitis, granulomatous amoebic encephalitis, and chronic granulomatous lesions. Soil and water samples were taken from experimental station at Julianna Major of Plant Protection Institut...

Members of Acanthamoeba cause three main types of illness involving the brain and spinal cord (Granulomatous encephalitis), the eye (Acanthamoeba keratitis), and infections that can spread throughout the entire body (disseminated infection). A total of 96 water samples (Nile, ground, tap and swimming pool) were collected for detection of Acanthamoeba species that were cultivated on non-nutrient...

To determine the pathogenicity of Acanthamoeba spp. isolated in Korea and to develop a isoenzymatic maker, the mortality rate of infected mice, in vitro cytotoxicity against target cells and isoenzyme band patterns were observed. Five isolates of Acanthamoeba spp. (YM-2, YM-3, YM-4, YM-5, and YM-7) were used in this study as well as three reference Acanthamoeba spp. (A. culbertsoni, A. hatchett...
