Vibrio alginolyticus-associated wound infection acquired in British waters, Guernsey, July 2011.

In July 2011, a Vibrio alginolyticus infection was diagnosed in a woman from Guernsey in the Channel Islands, British Isles after sea bathing and application of a natural seaweed dressing to a pre-existing leg wound. Microbiological investigation confirmed Vibrio in the wound and the species of seaweed used for the dressing. The washing of open wounds in seawater and use of unsterilised seaweed dressings should be discouraged, particularly in individuals with underlying risk conditions.
