Vibrio tubiashii has been linked to disease outbreaks in molluscan species, including oysters, geoducks, and clams, and shellfish hatcheries in the Pacific Northwest have been plagued by intermittent vibriosis outbreaks since 2006. Like V. tubiashii, Vibrio coralliilyticus has recently been described as an oyster pathogen in addition to its role in coral disease. Here, we describe an autolysis phenotype in V. tubiashii and its close relative V. coralliilyticus and characterize the effects of environmental conditions on this phenotype. We also explored whether the survivors of autolysis were resistant to the phenotype and if material from the autolysed culture would either regrow or have a population of viable cells. Ultimately, this work contributes to the larger understanding of bacterial population dynamics as it relates to aquaculture pathogens.
已经有研究表明，海洋弯曲杆菌与软体动物（包括牡蛎、象拔蚌和蛤）的疾病爆发有关，自 2006 年以来，西北太平洋地区的贝类孵化场间歇性地爆发了弧菌病。与海洋弯曲杆菌类似，珊瑚弧菌最近被描述为牡蛎病原体，除了在珊瑚疾病中的作用外。在这里，我们描述了海洋弯曲杆菌及其近亲珊瑚弧菌的自溶表型，并研究了环境条件对这种表型的影响。我们还探讨了自溶后存活下来的细菌是否对该表型具有抗性，以及自溶培养物的物质是否会重新生长或具有存活细胞的种群。总的来说，这项工作有助于更好地了解与水产养殖病原体有关的细菌种群动态。
