Regulation of microbial populations by coral surface mucus and mucus-associated bacteria
Open accessAbstract
Caribbean populations of the elkhorn coral Acropora palmata have declined due to environmental stress, bleaching, and disease.Potential sources of coral mortality include invasive microbes that become trapped in the surface mucus and thrive under conditions of increased coral stress.In this study, mucus from healthy A. palmata inhibited growth of potentially invasive microbes by up to 10-fold.Among cultured bacteria from the mucus of A. palmata, 20% displayed antibiotic activity against one or more tester strains, including the pathogen implicated in white pox disease.A novel mucusmediated selection for coral symbionts revealed a discrete subset of bacteria and selected for isolates that produce antibiotics.This result suggests that coral mucus plays a role in the structuring of beneficial coral-associated microbial communities and implies a microbial contribution to the antibacterial activity described for coral mucus.Interestingly, antibiotic activity was lost when mucus was collected during a summer bleaching event.Isolates from apparently healthy A. palmata tissue during this event lacked antibiotic-producing bacteria and were dominated by members of the genus Vibrio, including species implicated in temperature-dependent bleaching of corals worldwide.This indicates an environmental shift from beneficial bacteria, and variability in the protective qualities of coral mucus, which may lead to an overgrowth of opportunistic microbes when temperatures increase.Finally, coral mucus inhibited antibiotic activity and pigment production in a potentially invasive bacterium, illustrating that coral mucus may inactivate mechanisms used for bacterial niche establishment.

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.
