Phylogenetic relationships among nucleotide sequences of Blastocystis partial small subunit ribosomal RNA (SSU rRNA) gene. The neighbor-joining method was used to construct the trees by the Kimura two-parameter model. The number on the branches are percent bootstrapping values from 1000 replicates, with values of more than 50% shown in the tree. Each sequence is identified by its subtype, host, accession number, and country. Blastocystis subtypes identified in the present study are indicated in bold type
