Genome sequencing of Vibrio coralliilyticus RE22

Vibrio coralliilyticus strain RE22 is a naturally-occurring marine gammaproteobacterium that is pathogenic toward larval oysters. It was originally isolated from a shellfish hatchery on Netarts Bay, Oregon. This bacterium has been particularly problematic in shellfish hatcheries, where it has been associated with intermittent outbreaks of vibriosis and high mortalities of larval shellfish. Outbreaks of V. coralliilyticus in general have led to shortages of seed oysters needed for commercial shellfish operations. The RE22 strain was originally thought to be a Vibrio tubiashii; however, it was later identified as a V. coralliilyticus. This is the first complete genome of V. coralliilyticus (5,784,972 bp), which consists of two chromosomes (3,532,203 and 1,915,494 bp) and a megaplasmid (337,275 bp).

溶珊瑚弧菌（Vibrio coralliilyticus）菌株RE22是一种天然存在的海洋γ-变形菌纲细菌，对牡蛎幼体具有致病性。该菌株最初分离自美国俄勒冈州内特斯湾（Netarts Bay）的一处贝类育苗场。该菌在贝类育苗场中尤为棘手，常与间歇性弧菌病暴发及贝类幼体高死亡率相关。总体而言，溶珊瑚弧菌的暴发已导致商业贝类养殖所需的牡蛎苗种短缺。RE22菌株最初被误认为是管状弧菌（Vibrio tubiashii），后续经鉴定确认为溶珊瑚弧菌。本数据集包含溶珊瑚弧菌的首个完整基因组（总长度5,784,972 碱基对），该基因组由两条染色体（分别为3,532,203和1,915,494 碱基对）及一个巨型质粒（megaplasmid，337,275 碱基对）构成。
