Abstract
|
|
|
|
Vibrio vulnificus is opportunistic pathogen naturally occurring in coastal area that can cause acute sepsis. In this study, 61 isolates were investigated the characteristics of strains such as pathogenicity and antibiotic susceptibility in the west coastal area of Gyeonggi-do from 2016 to 2020. Most strains showed proteolytic activity and hemolytic activity. Polymerase Chain Reaction (PCR) method was used to detect virulence genes such as vvhA (100%), glnA (100%), pilA (31.1%), viuB (42.6%), wza (42.6%), and rtxA (42.6%). The results of antibiotic susceptibility tests to 27 different antibiotics presented 86.9~ 100% resistance to 5 antibiotics including penicillin and 1.6~55.7% intermediate resistance to 5 antibiotics including cefoxitin. Our findings revealed that Vibrio vulnificus isolated from environment may serve as potential human pathogen and one of strains showed intermediate resistance to chloramphenicol. These findings from this study were judged to be useful guidelines for prevention and antibiotic treatment to Vibrio vulnificus sepsis.
