Figure 2. Phylogenetic tree inferred from the small subunit rRNA sequences of microsporidia in this study and those in the GenBank database by using the maximum-likelihood method as implemented in MEGA5.05 software (2). Red circle indicates a novel microsporidium identified in this study (Microsporidium CU) that caused myositis. GenBank accession numbers are listed in parentheses after each species. Bootstrap percentages >50% based on 1,000 replicates are shown on the branches. The tree is drawn to scale, with branch lengths measured in the number of nucleotide substitutions per site.
