文摘

A strain of naked amoeba isolated from pikeperch (Sander lucioperca (L.)) kidney tissue has been characterized using light- and transmission electron microscopy. Sequencing of SSU rDNA and phylogenetic analysis based on a broad dataset of sequences completed our study. All data obtained suggest that this strain belongs to a species that has not been described before. As none of the existing genera of amoebae is applicable to this organism, the new genus Grellamoeba is established and the type species Grellamoeba robusta is described. Although the phylogenetic position of the SSU rDNA sequence of the type strain of G. robusta is sensitive to the method of analysis applied, a tendency to group with Acramoeba dendroida Smirnov, Nassonova et Cavalier-Smith, 2008 is evident.
