Rapid identification of thermophilic Naegleria, including Naegleria fowleri using API ZYM system.
The suitability of the API ZYM system for identifying thermophilic Naegleria species, based on enzyme presence and activity, was investigated. Replicate testing on strains of N fowleri, N lovaniensis, and N australiensis cultured in a monoxenic and an axenic medium showed that the system could provide a rapid and reproducible means of identifying the species soon after primary isolation. No sin...
متن کاملSpecificity of antibodies from human sera for Naegleria species.
Serum samples from adult humans in North Carolina and Pennsylvania were assayed for antibodies against four Naegleria species: N. australiensis, N. fowleri, N. gruberi, and N. lovaniensis. Agglutinating activities of serum samples from North Carolina subjects were higher for N. fowleri than were those from Pennsylvania subjects. The distributions of agglutination titers of human serum samples f...
متن کاملSurvey of Naegleria fowleri in Geothermal Recreational Waters of Guadeloupe (French West Indies)
In 2008 a fatal case of primary amoebic meningoencephalitis, due to the amoeboflagellate Naegleria fowleri, occurred in Guadeloupe, French West Indies, after a child swam in a bath fed with geothermal water. In order to improve the knowledge on free-living amoebae in this tropical part of France, we investigated on a monthly basis, the presence of Naegleria spp. in the recreational baths, and s...
متن کاملRapid, sensitive, and discriminating identification of Naegleria spp. by real-time PCR and melting-curve analysis.
The free-living amoeboflagellate genus Naegleria includes one pathogenic and two potentially pathogenic species (Naegleria fowleri, Naegleria italica, and Naegleria australiensis) plus numerous benign organisms. Monitoring of bathing water, water supplies, and cooling systems for these pathogens requires a timely and reliable method for identification, but current DNA sequence-based methods ide...
متن کاملCytopathology of pathogenic and nonpathogenic Naegleria species for cultured rat neuroblastoma cells.
The cytopathology for rat neuroblastoma cells (B-103) and the pathogenicity for B6C3F1 mice of four species of Naegleria have been compared. Both live amoebae and cell-free extracts of N. australiensis, N. fowleri, N. gruberi, and N. lovaniensis added to 51Cr-labeled B-103 cells caused release of radiolabel. All four species of Naegleria exhibited surface extensions termed food cups. Only N. fo...
