【 摘 要 】

ABSTRACT: The ribosomal RNA (rRNA) gene region of the microsporidium Heterosporis anguillarum has been examined. Complete DNA sequence data (4060 bp, GenBank Accession No. AF402839) of the rRNA gene of H. anguillarum arepresented for the small subunit gene (SSU rRNA: 1359 bp), the internal transcribed spacer (ITS: 37 bp), and the large subunit gene (LSU rRNA: 2664 bp). The secondary structures of the H. anguillarum SSU and LSU rRNA genes are constructed anddescribed. This is the first complete sequence of an rRNA gene published for a fish-infecting microsporidian species. In the phylogenetic analysis, the sequences, including partial SSU rRNA, ITS, and partial LSU rRNA sequences of the fish-infectingmicrosporidia, were aligned and analysed. The taxonomic position of H. anguillarum as suggested by Lom et al. (2000; Dis Aquat Org 43:225-231) is confirmed in this paper.
