초록

Background: Vibrio vulnificus is a serious opportunistic human pathogen that has a worldwide distribution in a variety of marine and estuarine environments.
Objectives: For this reason, we investigated the distribution of Vibrio vulnificus in coastal areas of Gyeonggi- do Province from 2018 to 2022. Also, we analyzed the correlation between V. v u l n i f i c u s leading to infection and two marine environmental factors (water temperature and salinity).
Methods: We collected a total of 266 samples from six coastal area points (i.e., seawater, mudf lats). Specimens were isolated using selective plating media and isolated strains were identified by a VITEK 2 system. To find the relevance of the isolation rates of V. vulnificus and number of cases of V. vulnificus infection, we summarized the data on 48 cases of V. v u l n i f i c u s infection from the open data of the Korea Disease Control and Prevention Agency.
Results: Among the 266 samples taken during the investigation period, 47 strains were isolated, and the separation rates of V. v u l n i f i c u s were 17.7%. The monthly isolation rates of V. v u l n i f i c u s were ranked in the order of August (53.8%), September (33.3%), June (28.6%), and July (21.1%). There was a positive correlation with the temperature of seawater, but salinity was not significant. The number of cases of V. v u l n i f i c u s infection reported in Gyeonggi-do Province were 18 (37.5%) in September, 14 (29.2%) in August, and eight (16.7%) in October. The proportion was 83.3%. It was relevant to the isolation rates of V. vulnificus in the marine environmental sources.
Conclusions: Our data showed that the number of V. v u l n i f i c u s infection cases could be affected by changes in the distribution of V. v u l n i f i c u s due to rise the temperature of seawater in the marine environment.
