The oral and bronchial strains were compared mutually as well as with a reference strain of<jats:italic>Trichomonas tenax<\/jats:italic>, a common inhabitant of the human oral cavity, and other trichomonad species from humans and animals. Unexpectedly, the morphological studies, as well as DNA sequencing of ITS1-5.8S rRNA-ITS2 regions revealed that the Estonian strains belong to the genus<jats:italic>Tetratrichomonas<\/jats:italic>, with a high similarity to the avian species<jats:italic>Tetratrichomonas gallinarum<\/jats:italic>. None of the strains belonged to<jats:italic>Trichomonas tenax<\/jats:italic>. DNA fingerprinting using the RAPD method separated Estonian strains into 2 distinct groups: \u2018bronchial\u2019 consisting of 5 and 2 strains isolated from bronchi and \u2018oral\u2019 cavity, respectively, and oral consisting of 3 oral strains. Consistent differences between \u2018bronchial\u2019 and \u2018oral\u2019 groups were confirmed by analysis of ITS1-5.8S rRNA-ITS2 sequences. Our results have revealed novel trichomonad species of the human oral cavity and bronchi.<\/jats:p>","DOI":"10.1017\/s0031182005008000","type":"journal-article","created":{"date-parts":[[2005,6,10]],"date-time":"2005-06-10T13:11:02Z","timestamp":1118409062000},"page":"309-319","source":"Crossref","is-referenced-by-count":59,"title":["Tetratrichomonads from the oral cavity and respiratory tract of humans"],"prefix":"10.1017","volume":"131","author":[{"given":"K.","family":"KUTISOVA","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"KULDA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"CEPICKA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"FLEGR","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"KOUDELA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"TERAS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"TACHEZY","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2005,6,10]]},"reference":[{"key":"S0031182005008000_ref057","doi-asserted-by":"crossref","unstructured":"Walker, R.
