Phylogenetic relationships of Enterocytozoon bieneusi groups. The relationships between E. bieneusi genotypes identified in this study and other known genotypes deposited in the GenBank were inferred by a neighbor-joining analysis of internal transcribed spacer sequences based on genetic distance by the Kimura-2-parameter model. The numbers on the branches represent percent bootstrapping values from 1000 replicates, with values of more than 50 % shown in the tree. Each sequence is identified by its accession number, genotype designation and host origin. Genotypes marked with black triangles and black circles are novel and known genotypes identified in this study, respectively
