However, emerging data show that asymptomatic carriage is common and that <jats:italic>Blastocystis<\/jats:italic> is prevalent in the healthy adult gut microbiota. Nonetheless, little is known about the prevalence and diversity of this microorganism in the healthy infant gut, including when and how individuals become colonized by <jats:italic>Blastocystis<\/jats:italic>. Here, we surveyed the prevalence and diversity of <jats:italic>Blastocystis<\/jats:italic> in an infant population (<jats:italic>n<\/jats:italic> = 59) from an industrialized country (Ireland) using <jats:italic>Blastocystis<\/jats:italic>-specific primers at three or more time-points up to 24 months old. Only three infants were positive for <jats:italic>Blastocystis<\/jats:italic> (prevalence = 5%) and this was only noted for samples collected at month 24. This rate is comparatively low relative to previously reported prevalence rates in the contemporaneous adult population. These data suggest that infants in Westernized countries that are successfully colonized by <jats:italic>Blastocystis<\/jats:italic> most likely acquire this microorganism <jats:italic>via<\/jats:italic> horizontal transfer.<\/jats:p>","DOI":"10.1017\/s0031182018000033","type":"journal-article","created":{"date-parts":[[2018,2,5]],"date-time":"2018-02-05T00:49:17Z","timestamp":1517791757000},"page":"1274-1278","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":13,"title":["The intestinal protist <i>Blastocystis<\/i> is not a common member of the healthy infant gut microbiota in a Westernized country (Ireland)"],"prefix":"10.1017","volume":"145","author":[{"given":"P.
