‘Vibrio vulnificus is in Charleston Harbor’: Charleston researchers track bacteria, what doctors warn

Key Points:

• Vibrio vulnificus, a flesh-eating bacterium found in Charleston Harbor, can cause rapid and severe infections, sometimes leading to amputation within a day, according to the Medical University of South Carolina (MUSC).
• Biology professor Michael Janech has been monitoring Vibrio levels in Charleston waters for three years, noting that the bacteria thrive in warmer temperatures, especially between June and August, with populations increasing significantly when water temperatures reach around 72-77 degrees Fahrenheit.
• While most Vibrio species are harmless and play a role in the ecosystem, Vibrio vulnificus is particularly dangerous, with MUSC reporting three cases this season; infections can occur through consuming contaminated seafood or wounds exposed to brackish or saltwater.
• MUSC infectious disease physician Scott Curry emphasizes the importance of immediate medical attention for any skin infections following marine injuries, as the infection can progress rapidly and may require surgical intervention rather than just antibiotic treatment.
• Warning signs of Vibrio vulnificus infection include fluid-filled blisters under the skin that become tight and may burst, redness, and swelling; individuals experiencing these symptoms after water exposure should seek emergency care promptly rather than waiting to see a primary care physician.
