Phylogenetic tree of Encephalitozoon spp. and Enterocytozoon bieneusi isolates and selected accessions from GenBank, based on small subunit ribosomal RNA gene fragment sequences. The phylogenetic tree was constructed using nucleotide sequence alignments, with the Kimura two-parameter algorithm as the distance method and neighbor-joining as the tree composition method. The black squares indicate the known genotypes identified in this study. The sequence of Nosema bombycis was used as the outgroup.
