Despite a century of intense study, understanding of the epidemiology of<jats:italic>Blastocystis<\/jats:italic>remains fragmentary. Here, we aimed to explore its prevalence, stability of colonisation and association with various factors in a rural elementary school in northern Thailand. One hundred and forty faecal samples were collected from 104 children at two time points (tp) 105 days apart. For tp2, samples were also obtained from 15 animals residing on campus and seven water locations. Prevalence in children was 67% at tp1 and 89% at tp2, 63% in chickens, 86% in pigs, and 57% in water. Ten STs were identified, two of which were shared between humans and animals, one between animals and water, and three between humans and water. Eighteen children (out of 36) carried the same ST over both time points, indicating stable colonisation. Presence of<jats:italic>Blastocystis<\/jats:italic>(or ST) was not associated with body mass index, ethnicity, birth delivery mode, or milk source as an infant. This study advances understanding of<jats:italic>Blastocystis<\/jats:italic>prevalence in an understudied age group, the role of the environment in transmission, and the ability of specific STs to stably colonise children.<\/jats:p>","DOI":"10.1017\/s0950268823000596","type":"journal-article","created":{"date-parts":[[2023,4,27]],"date-time":"2023-04-27T08:33:23Z","timestamp":1682584403000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":14,"title":["Circulation and colonisation of<i>Blastocystis<\/i>subtypes in schoolchildren of various ethnicities in rural northern Thailand"],"prefix":"10.1017","volume":"151","author":[{"given":"Abby","family":"McCain","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucsame","family":"Gruneck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siam","family":"Popluechai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5424-1905","authenticated-orcid":false,"given":"Anastasios D.","family":"Tsaousis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleni","family":"Gentekaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,4,27]]},"reference":[{"key":"S0950268823000596_r74","volume-title":"R: A Language and Environment for Statistical Computing","year":"2020"},{"key":"S0950268823000596_r94","doi-asserted-by":"publisher","DOI":"10.3389\/fcimb.2018.00371"},{"key":"S0950268823000596_r21","doi-asserted-by":"publisher","DOI":"10.1016\/j.actatropica.2012.12.011"},{"key":"S0950268823000596_r99","doi-asserted-by":"publisher","DOI":"10.3390\/metabo11120883"},{"key":"S0950268823000596_r85","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-022-04662-x"},{"key":"S0950268823000596_r1","doi-asserted-by":"publisher","DOI":"10.1016\/j.protis.2013.05.003"},{"key":"S0950268823000596_r95","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.02520-15"},{"key":"S0950268823000596_r2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0169659"},{"key":"S0950268823000596_r3","doi-asserted-by":"publisher","DOI":"10.3389\/fcimb.2020.544335"},{"key":"S0950268823000596_r8","doi-asserted-by":"publisher","DOI":"10.3389\/fvets.2021.732129"},{"key":"S0950268823000596_r12","doi-asserted-by":"publisher","DOI":"10.1016\/j.pt.2012.05.004"},{"key":"S0950268823000596_r26","doi-asserted-by":"publisher","DOI":"10.1007\/s00436-011-2626-7"},{"key":"S0950268823000596_r31","doi-asserted-by":"publisher","DOI":"10.1007\/s00436-010-1761-x"},{"key":"S0950268823000596_r37","doi-asserted-by":"publisher","DOI":"10.1186\/s13071-019-3641-2"},{"key":"S0950268823000596_r76","doi-asserted-by":"crossref","first-page":"352","DOI":"10.4269\/ajtmh.2012.12-0237","article-title":"Identification of Blastocystis subtype 1 variants in the home for girls, Bangkok, Thailand","volume":"88","author":"Leelayoova","year":"2013","journal-title":"American Journal of Tropical Medicine and Hygiene"},{"key":"S0950268823000596_r28","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0015484"},{"key":"S0950268823000596_r42","doi-asserted-by":"publisher","DOI":"10.1007\/s10096-019-03710-z"},{"key":"S0950268823000596_r51","doi-asserted-by":"publisher","DOI":"10.1186\/s13071-020-3890-0"},{"key":"S0950268823000596_r10","doi-asserted-by":"publisher","DOI":"10.1016\/j.parepi.2020.e00138"},{"key":"S0950268823000596_r18","doi-asserted-by":"publisher","DOI":"10.1016\/j.meegid.2016.03.017"},{"key":"S0950268823000596_r96","doi-asserted-by":"publisher","DOI":"10.1007\/s40200-019-00483-2"},{"key":"S0950268823000596_r15","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2021.746340"},{"key":"S0950268823000596_r17","first-page":"669","article-title":"Epidemiological and molecular characterization of Blastocystis infection in children attending daycare centers in Medell\u00edn, Colombia","volume":"10","author":"Osorio-Pulgarin","year":"2021","journal-title":"Biology (Basel)"},{"key":"S0950268823000596_r69","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msz312"},{"key":"S0950268823000596_r16","doi-asserted-by":"publisher","DOI":"10.3390\/microorganisms8091408"},{"key":"S0950268823000596_r4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1550-7408.2006.00141.x"},{"key":"S0950268823000596_r73","unstructured":"[73] Warnes, GR , Bolker, B , Bonebakker, L , Gentleman, R , Huber, W , Liaw, A , Lumley, T , Maechler, M , Magnusson, A , Moeller, S , Schwartz, M and Venables, B (2020) gplots: Various R programming tools for plotting data.
