The human oral cavity is host to a complex microbial community estimated to comprise >700 bacterial species, of which at least half are thought to be not yet cultivable in vitro. To investigate the plasmids present in this community, we used a transposon-aided capture system, which allowed the isolation of plasmids from human oral supra- and subgingival plaque samples. Thirty-two novel plasmids and a circular molecule that could be an integrase-generated circular intermediate were isolated.
人类口腔是一个复杂的微生物群落的宿主,据估计该群落包含超过 700 种细菌,其中至少有一半被认为是目前还不能在体外培养的。为了研究该群落中存在的质粒,我们使用了转座子辅助捕获系统,该系统允许从人类口腔龈上和龈下菌斑样本中分离质粒。我们共分离到 32 种新型质粒和一种可能是整合酶产生的环形中间产物的环形分子。
