Phylogenetic analysis of internal transcribed spacer (ITS) of nuclear ribosomal DNA sequence data (cf. Additional file 1: Table S1) by Bayesian inference (BI). Included here are ITS sequences of (i) E. bieneusi genotypes representing all currently recognised Groups (1 to 10) from the published literature, (ii) four genotypes of Enterocytozoon identified in the present study (bold-type) and (iii) the outgroup taxa. Statistically significant posterior probabilities (pp) of > 0.95 are indicated on branches. The scale-bar represents the number of substitutions per site. * = novel genotype
