Here, we investigated V. aestuarianus infection onset and progression in the wild, taking advantage of a “claire” pond: a semi‐closed system with limited seawater renewal, theoretically more adapted to disease transmission. We showed a positive association of the bacteria with oysters, which can constitute a reservoir for the bacteria in the winter. Moreover, passage through oysters was found to be necessary for experimental disease reproduction as vibrios shedding from diseased oysters has higher infectivity than from in vitro grown. We next developed an experimental “ecologically realistic” infection model in a mesocosm, allowing infection by natural route. By means of this non‐invasive protocol, we analysed the pathogenesis of the bacteria and demonstrated the importance of haemolymph for initial colonisation and the septicaemic nature of this disease.
