초록
The pathogenic Vibrio genus contains halophilic bacteria that are distributed in marine and freshwater environments. Vibrio cholerae, Vibrio vulnificus, and Vibrio parahaemolyticus are potent human pathogens and leading causes of septicemia, wound infection, and seafood-borne gastroenteritis. The aim of this study was to investigate the presence of pathogenic Vibrio species in seawater off the west coast of Korea. Sixty-four seawater samples were obtained from different sites in Gomso Bay and Byeonsan from April 2018 to November 2018. Pathogenic Vibrio species were detected using a combination of most probable number (MPN)-polymerase chain reaction methods. V. cholerae, V. vulnificus, and V. parahaemolyticus were found in 0.0%, 20.3%, and 65.6% of seawater samples, respectively. Quantitative results revealed 3.6-23 MPN/100 mL of V. vulnificus, and 3.6-930 MPN/100 mL of V. parahaemolyticus in the samples. Overall, these results provide new insight into the necessity for seawater sanitation in Gomso Bay and Byunsan; they also provide evidence that will help reduce outbreaks of seafood-borne illness caused by pathogenic Vibrio species.
Abstract
