| Un outil de signalement des hausses de mortalité d’huîtres par SMS a été testé en Normandie entre le 1er juin et le 31 décembre 2016. Il localise, en temps quasi-réel, les regroupements spatio-temporels de mortalité d’huîtres, qui reflètent potentiellement un foyer infectieux. Cet outil permet de cibler les interventions telles que les prélèvements de coquillages à envoyer au laboratoire d’analyses diagnostiques, pour détecter rapidement une maladie émergente ou exotique dans les eaux françaises. |

| Vibrio aestuarianus infection in oyster populations causes massive mortality, resulting in losses for oyster farmers. Such dynamics result from host-pathogen interactions and contagion through water-borne transmission. To assess the spatiotemporal spread of V. aestuarianus infection and associated oyster mortality at a bay scale, we built a mathematical model informed by experimental infection data at 2 temperatures and spatially dependent marine connectivity of oyster farms. We applied the model to a real system and tested the importance of each factor using a number of modelling scenarios. Results suggest that introducing V. aestuarianus in a fully susceptible adult oyster population in the bay would lead to the mortality of all farmed oysters over 6 to... |
