Rising temperatures are causing a "growing diversity" of Vibrio bacteria in the sea around the UK, new research shows.
The study, led by the University of Exeter, found two Vibrio species – Vibrio rotiferianus and Vibrio jasicida – that have never been recorded in UK waters before.
These species can harm sea creatures such as shellfish, but the increasing range of Vibrio species also raises concerns for human health.
Some Vibrio bacteria can cause gastroenteritis when eaten in raw or undercooked shellfish, and the bacteria can also cause skin infections.
The researchers say the spread of Vibrio species has resulted in a "worldwide surge" of Vibriosis infections in humans and aquatic animals.
"Vibrio species can often be found in UK waters in summer, when temperatures are more favourable for them," said Dr Sariqa Wagley, of the University of Exeter.
"With sea-surface temperatures rising due to climate change, Vibrio activity in the waters is more common, and the diversity of Vibrio species is now increasing."
