Vibrio vulnificus is the leading cause of seafood‐associated deaths worldwide. Despite the growing knowledge about the population structure of V. vulnificus, the evolutionary history and the ancestral relationships of strains isolated from various regions around the world have not been determined. Using the largest collection of sequence and isolate data of V. vulnificus to date, we applied ancestral character reconstruction to study the phylogeography of V. vulnificus. Multilocus sequence typing data from 10 housekeeping genes were used for the inference of ancestral states and reconstruction of the evolutionary history. The findings showed that the common ancestor of all V. vulnificus populations originated from East Asia, and later evolved into two main clusters that spread with time and eventually evolved into distinct populations in different parts of the world. While we found no meaningful insights concerning the evolution of V. vulnificus populations in the Middle East; however, we were able to reconstruct the ancestral scenarios of its evolution in East Asia, North America, and Western Europe.

海洋病原体弧菌的系统志揭示了其进化的祖先情景。

创伤弧菌是世界范围内与海鲜相关的死亡的主要原因。尽管对V的人口结构的知识越来越多。尚未确定从世界各地分离出的毒株的 创伤史，进化史和祖先关系。使用最大的V序列和分离数据集合。 创伤弧菌到今天为止，我们采用祖传字符重建研究的系统地理学V。 创伤。来自10个管家基因的多基因座序列分型数据用于推断祖先状态和重建进化史。研究结果表明，所有V的共同祖先。 创伤人口起源于东亚，后来演变成两个主要的群体，随着时间的流逝而发展，最终演变成世界不同地区的不同群体。虽然我们没有发现有关V演化的有意义的见解。中东的 外伤人口；但是，我们能够重建其在东亚，北美和西欧发展的祖先情景。
