In vitro susceptibility of pathogenic Naegleria and Acanthamoeba speicies to a variety of therapeutic agents.
Six pathogenic strains of Naegleria fowleri, two of Acanthamoeba castellanii, and three of Acanthamoeba polyphaga were tested in vitro for susceptibility to a variety of potentially useful therapeutic agents. Minimal motility inhibitory concentrations and minimal inhibitory concentrations were determined by a technique of subculturing pure clones of amoebae in plastic tissue culture chamber sli...
متن کاملDetection of free living amoebae, Acanthamoeba and Naegleria, in swimming pools, Malaysia.
This study reports the detection of Acanthamoeba and Naegleria species in 14 swimming pools around Petaling Jaya and Kuala Lumpur, Malaysia. Sampling was carried out at 4 sites (the platforms (P), wall (W), 1 meter from the wall (1) and middle (2)) of each swimming pool. These free living amoebae (FLA) were detected under light and inverted microscopes after being cultured on the surface of non...
متن کاملFree-living Acanthamoeba and Naegleria spp. amebae in water sources of León, Nicaragua.
Free-living amebae (FLA) are known to occur worldwide in water-related biotopes, but only limited information is available on these organisms in developing countries and so far no information on their presence is available from Nicaragua. The aims of this study were to evaluate the prevalence of potentially pathogenic Acanthamoeba spp. and Naegleria spp. in different water sources to which the ...
متن کاملOccurrence of Acanthamoeba Genotypes in Wastewater Samples in Tehran, Iran
Background Acanthamoeba spp. is potentially pathogenic free-living amoeba that can exist in various water sources. The presence of this amoeba in water sources could be a health hazard as Acanthamoeba could lead to severe diseases such as Acanthamoeba keratitis and encephalitis. This study aimed to determine the genotypes of isolated Acanthamoeba spp. in raw wastewater samples in Tehran, Iran. ...
متن کاملElastase in the pathogenic free-living amoebae Naegleria and Acanthamoeba spp.
The data showed that pathogenic free-living amoebae contain the proteolytic enzyme elastase. The levels of enzyme were similar in Naegleria fowleri, N. australianis italica, and Acanthamoeba culbertsoni A-1. No difference was found between elastase levels in a highly pathogenic N. fowleri and those in the same organism which had lost pathogenicity as a result of long-term axenic maintenance.
