Phylogenetic analysis of internal transcribed spacer (ITS) of nuclear ribosomal DNA sequence data (Additional file 2: Table S2) by Bayesian inference (BI). Included here are ITS sequences of (i) E. bieneusi genotypes representing all currently recognised Groups (1 to 9) from the published literature; (ii) five genotypes of Enterocytozoon identified in the present study (bold-type); and (iii) the outgroup taxa. Groups 10 and 11 are proposed based on the results of the present analysis. Statistically significant posterior probabilities (pp) are indicated on branches. The scale-bar represents the number of substitutions per site
