Dentro este grupo están: Acanthamoeba, Naegleria, Balamuthia y Sappinia; capaces producir el ser humano distintas enfermedades, desde cuadros agudos fatales, a enfermedades crónicas con una reacción inflamat...
In a survey from 1999 to 2001, a total of 354 samples of soil and water were colleted from different areas and examined for the presence of AcanthamoebaandNaegleria spp. After sieving, filtration and centrifugation, samples were examined for the free living protozoa ( amphizoic amoeba ). Concurrently, a sediment of each sample was cultured in the non-nutrient agar medium enriched by E.coli. In ...
A new method for the rapid and accurate detection of pathogenic Naegleria fowleri amoebae in surface environmental water was developed. The method is based on an immunofluorescent assay combined with detection by solid-phase cytometry. In this study we developed and compared two protocols using different reporter systems conjugated to antibodies. The monoclonal antibody Ac5D12 was conjugated wi...
Naegleria fowleri, the causative agent of primary amebic meningoencephalitis, is resistant to complement lysis. The presence of a complement regulatory protein on the surface of N. fowleri was investigated. Southern blot and Northern blot analyses demonstrated hybridization of a radiolabeled cDNA probe for CD59 to genomic DNA and RNA, respectively, from pathogenic N. fowleri. An 18-kDa immunore...
