[Isolation and identification of 2 new pathogenic strains of Naegleria australiensis]

We report here the isolation of two pathogenic Naegleria strains which by their biological (thermotolerance, axenisation, pathogenicity), biochemical (zymogram patterns), and antigenic characters can be identified as belonging to N. australiensis whereas only one strain (type species PP 397) was known until now. The pathogenicity among this genus of free-living amoebas is no more an exclusive feature of N. fowleri.
