Molecular phylogenetic relationships between various Blastocystis sp. samples isolated from rats as inferred by the Neighbour-Joining tree based on the 18S rRNA gene. The numbers on branches are percentage bootstrap values of 1000 replicates. The evolutionary distances between sequences were computed using the Maximum Composite Likelihood method. The scale-bar indicates an evolutionary distance of 0.01 nucleotides per position in the sequence. The reference sequence accession numbers are shown. Evolutionary analyses were conducted in MEGA-X. Blastocystis lapemi was used as the outgroup
