ABSTRACT
The potential to produce and release outer membrane vesicles (OMVs) is evolutionarily conserved among bacteria, facilitating interactions between microbes. OMV release and its ecological significance have rarely been reported in coral holobionts. Here, via transmission electron microscopy (TEM), we discovered that the coral-associated strain Vibrio coralliilyticus DSM 19607 produced OMVs in culture. OMVs purified from V. coralliilyticus DSM 19607 inhibited the bacteriophage (phage) SBM1 infection of the V. coralliilyticus host, which was impaired by elevated temperature. Observation via TEM showed that sequestrating phages was a potential approach for V. coralliilyticus OMVs protection against phage infection. Furthermore, detection in coral mucus showed that interactions between membrane vesicles and phages potentially occurred in the natural environment. These results imply that OMVs regulate the coral microbiome and may have important implications for our mechanistic understanding of coral health and disease in the face of climate change.
