title: Molecular Identification and Subtype Analysis of Blastocystis.
abstract: Several typing methods have been used in studies aiming to unravel the molecular epidemiology of Blastocystis, which is one of the most common intestinal parasites in human and many non-human hosts. Such studies have the potential to add to knowledge on Blastocystis transmission, host specificity, phylogeography, and clinical and public health significance, but rely on robust, standardized methods by which data can be generated and compared directly between studies. One of the most used methods is "barcoding,", which involves single-round PCR amplification and sequencing of partial small subunit ribosomal RNA genes of the parasites. Recently, a publicly available online facility was developed for quick and standardized identification of subtypes (ribosomal lineages) and subtype alleles (variation within subtypes) based on sequence data obtained by barcoding PCR. Moreover, a modified barcoding approach is now available using nested PCR, which enables detection of mixed subtype infections. © 2016 by John Wiley & Sons, Inc.
