Members of the genus Vibrio are common in aquatic environments. Among them are V. cholerae, V. vulnificus, V. parahaemolyticus and V. mimicus. Several studies have shown that environmental factors, such as temperature, salinity, and dissolved oxygen, are involved in their epidemiology. Therefore, the main objective of this study is to determine if there is a correlation between the presence/amount of V. cholerae, V, vulnificus, V. parahaemolyticus and V. mimicus and the environmental conditions of the seawater off the coast of Guaymas, México. Quantification of all four pathogenic bacteria was performed using the most probable number method, and suspected colonies were identified by polymerase chain reaction (PCR). Correlations were found using principal component analysis. V. parahaemolyticus was the most abundant and widely distributed bacteria, followed by V. vulnificus, V. mimicus and V. cholerae. Positive correlations between V. parahaemolyticus, V. vulnificus and V. mimicus with temperature, salinity, electric conductivity, and total dissolved solids were found. The abundance of V. cholerae was mainly affected by the sampling site and not by physicochemical parameters.
弧菌属的成员在水生环境中很常见。其中包括霍乱弧菌、创伤弧菌、副溶血性弧菌和拟态弧菌。多项研究表明，环境因素，如温度、盐度和溶解氧，与它们的流行病学有关。因此，本研究的主要目的是确定墨西哥瓜伊马斯海岸外海水中是否存在霍乱弧菌、创伤弧菌、副溶血性弧菌和拟态弧菌的存在/数量与环境条件之间的相关性。使用最可能数法对所有四种致病性细菌进行定量，并用聚合酶链反应（PCR）鉴定可疑菌落。使用主成分分析发现相关性。副溶血性弧菌是最丰富和分布最广的细菌，其次是创伤弧菌、拟态弧菌和霍乱弧菌。副溶血性弧菌、创伤弧菌和拟态弧菌与温度、盐度、电导率和总溶解固体之间存在正相关。霍乱弧菌的丰度主要受采样地点而不是理化参数的影响。
