FIG 1.

Phylogenetic relationship of ITS nucleotide sequences of Enterocytozoon bieneusi in this study and known E. bieneusi genotypes, as inferred by a neighbor-joining analysis (Mega 4 software, http://www.megasoftware.net/) based on genetic distances calculated using the Kimura two-parameter model. The ITS tree was rooted with GenBank sequence DQ885585. Bootstrap values >75% from 1,000 pseudoreplicates are shown. NEC1 to NEC5, marked with black triangles, are new genotypes found in this study; the known genotypes detected are indicated by white triangles.
