Analysis by biochemical testing and polyacrylamide gel electrophoresis of whole-cell proteins indicated that the strains closely resembled each other phenotypically but were distinct from previously described <jats:italic>Actinomyces<\/jats:italic> and<jats:italic>Arcanobacterium<\/jats:italic> species. Comparative 16S rRNA gene-sequencing studies showed the bacterium to be a hitherto unknown subline within a group of <jats:italic>Actinomyces<\/jats:italic> species which includes <jats:italic>Actinomyces bovis<\/jats:italic>, the type species of the genus. Based on phylogenetic and phenotypic evidence, we propose that the unknown bacterium isolated from human clinical specimens be classified as <jats:italic>Actinomyces radicidentis<\/jats:italic> sp. nov. The type strain of<jats:italic>Actinomyces radicidentis<\/jats:italic> is CCUG 36733.<\/jats:p>","DOI":"10.1128\/jcm.38.9.3399-3403.2000","type":"journal-article","created":{"date-parts":[[2019,12,31]],"date-time":"2019-12-31T17:59:08Z","timestamp":1577815148000},"page":"3399-3403","source":"Crossref","is-referenced-by-count":62,"title":["Characterization of Actinomyces Isolates from Infected Root Canals of Teeth: Description of Actinomyces radicidentis sp. nov."],"prefix":"10.1128","volume":"38","author":[{"given":"Matthew D.","family":"Collins","sequence":"first","affiliation":[{"name":"Department of Food Science and Technology, University of Reading, Reading RG6 6AP, United Kingdom\n1\n;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lesley","family":"Hoyles","sequence":"additional","affiliation":[{"name":"Department of Food Science and Technology, University of Reading, Reading RG6 6AP, United Kingdom\n1\n;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sotos","family":"Kalfas","sequence":"additional","affiliation":[{"name":"Division of Oral Microbiology, Department of Odontology,\n2"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Goran","family":"Sundquist","sequence":"additional","affiliation":[{"name":"Division of Endodontics, Department of Odontology,\n3\n and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tor","family":"Monsen","sequence":"additional","affiliation":[{"name":"Department of Clinical Bacteriology,\n4\n Umea University, 90185 Umea, Sweden;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Nikolaitchouk","sequence":"additional","affiliation":[{"name":"Culture Collection, Department of Clinical Bacteriology, University of Go\u0308teborg, S-413 46 Go\u0308teborg, Sweden\n5\n; and"},{"name":"Department of Microbiology, Russian Peoples Friendship University, Moscow, Russia\n6"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enevold","family":"Falsen","sequence":"additional","affiliation":[{"name":"Culture Collection, Department of Clinical Bacteriology, University of Go\u0308teborg, S-413 46 Go\u0308teborg, Sweden\n5\n; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","container-title":["Journal of Clinical Microbiology"],"original-title":[],"language":"en","deposited":{"date-parts":[[2021,7,29]],"date-time":"2021-07-29T18:42:49Z","timestamp":1627584169000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.asm.org\/doi\/10.1128\/JCM.38.9.3399-3403.2000"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2000]]}},"URL":"https:\/\/doi.org\/10.1128\/jcm.38.9.3399-3403.2000","relation":{},"ISSN":["1098-660X","0095-1137"],"issn-type":[{"value":"1098-660X","type":"electronic"},{"value":"0095-1137","type":"print"}],"subject":[],"published":{"date-parts":[[2000]]}}}
