Abstract:
Microsporidia are ubiquitous intracellular parasitic protozoa infecting all types of animals. Their ribosomes and rRNAs are of prokaryotic size.In order to better understand their phylogenetic relationship and identify the uncertain species, the sequences of the small subunit ribosomal RNA (ssurRNA, 16 S rRNA) genes of nine microsporidia infectious to the silkworm, Bombyx mori, were determined. The results of phylogenetic trees and Southern blotting suggest all the nine strains of microsporidia are various species of the genus Nosema.
