Phylogenetic relationships between genotype groups of Enterocytozoon bieneusi. The relationships were inferred using neighbor-joining analysis of internal transcribed spacer (ITS) sequences based on genetic distance calculated by the Kimura two-parameter model. Each sequence is marked with its accession number, host origin and genotype designation. The numbers on the branches are percentage bootstrapping values from 1,000 replicates. Open and solid circles, respectively, indicate previously known and novel sequences identified in this study.
