Abstract

Significance: The physiology and ecology of complex microbial communities are strongly dependent on the immediate surroundings of each microbe, including the identity of neighboring microbes; however, information on the micron-scale organization of microbiomes is largely lacking. Using sequencing data combined with spectral fluorescence imaging, we have discovered a multigenus, highly organized microbial consortium in human dental plaque. The spatial structure of the consortium reveals unanticipated interactions and provides a framework for understanding the organization, metabolism, and systems biology of the microbiome and ultimately, its effect on the health of the human host. Our synthesis of high-throughput sequencing data with spatial and structural information shows the informative value of microbial biogeography at the micron scale.

  • Spectral imaging and fluorescence in situ hybridization offer a different perspective of biofilm structure, in which a radially arranged consortium of bacteria forms along the annulus of filamentous Corynebacteria.

  • The oral cavity as a microbial environment is complicated by spatial gradients created by salivary flow, nutrient availability, oxygen concentration, saliva, and gingival crevicular fluids, in addition to regular environmental disturbances caused by eating and mastication, facial movement related to speaking and expression, and oral hygiene practices.

  • While traditional models recognize Fusobacterium as critical for connecting early and late biofilm successors, findings from this study instead found Corynebacterium as the cornerstone of biofilm development.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
