Fig. 1. Phylogenetic relationship among the Enterocytozoon bieneusi groups. The relationship between the E. bieneusi genotypes identified in this study and other known genotypes deposited in GenBank was inferred by neighbor-joining analysis of ITS sequences based on genetic distance using the Kimura-2-parameter model. The numbers on the branches represent percent bootstrapping values from 1000 replicates, with more than 50% shown in the tree. Each sequence is identified by its accession number, genotype designation, and host origin. Genotypes marked with black rhombuses and black triangles are novel and known genotypes identified in this study, respectively.
