Girard, Léa Quorum sensing in <i>Vibrio</i> spp.: the complexity of multiple signalling molecules in marine and aquatic environments <p>Quorum sensing (QS) is a density-dependent mechanism enabling bacteria to coordinate their actions <i>via</i> the release of small diffusible molecules named autoinducers (AIs). <i>Vibrio</i> spp. are able to adapt to changing environmental conditions by using a wide range of physiological mechanisms and many species pose a threat for human health and diverse marine and estuarine ecosystems worldwide. Cell-to-cell communication controls many of their vital functions such as niche colonization, survival strategies, or virulence. In this review, I summarize (1) the different known QS pathways (2) the diversity of AIs as well as their biological functions, and (3) the QS-mediated interactions between <i>Vibrio</i> and other organisms. However, the current knowledge is limited to a few pathogenic or bioluminescent species and in order to provide a genus-wide view an inventory of QS genes among 87 <i>Vibrio</i> species has been made. The large diversity of signal molecules and their differential effects on a particular physiological function suggest that the complexity of multiple signalling systems within bacterial communities is far from being fully understood. I question here the real level of specificity of such communication in the environment and discuss the different perspectives in order to better apprehend QS in natural habitats.</p> Marine environment;quorum sensing;Vibrio spp.;autoinducers 2019-06-26
