Genomic DNA was extracted using the QIAamp DNA Stool Mini Kit. PCR amplification was performed based on the SSU rRNA gene, and products were visualized on 1.5% agarose gels. Positive amplicons were randomly selected for sequencing, and STs were assigned by BLAST comparison with GenBank references. Phylogenetic relationships were constructed using MEGA X with the Neighbour\u2010Joining method. Statistical associations between infection and host variables were evaluated using chi\u2010square and Fisher's exact tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      <jats:italic>Blastocystis<\/jats:italic>\n                      sp. DNA was detected in 32 of 142 ruminant samples (22.5%). Prevalence was 19% (16\/84) in cattle, 27.3% (7\/26) in sheep and 28.1% (9\/32) in goats, with no significant difference among species (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.486).
