Phylogenetic relationship of ITS nucleotide sequences of <i>Enterocytozoon bieneusi</i> in this study and known <i>E. bieneusi</i> 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.

<p>The ITS tree was rooted with GenBank sequence DQ885585. Bootstrap values less than 65% from 1,000 pseudoreplicates are not shown. CC-1 indicated by white triangle is a new genotype found in this study.
