Scientists in the United Kingdom analyzed about 300 people and concluded that surfers harbor a lot more bacteria in their guts that are resistant to antibiotic medication, compared to people who swim in the sea but don’t surf.
Led by Dr. Anne Leonard from the University of Exeter Medical School, the researchers recruited 150 surfers and 150 non-surfers, all of whom frequent the coastline of the U.K. Since the intention was to test for the presence of bacteria in their guts, the study’s participants were all given rectal swabs to collect fecal samples.
After eliminating some samples for contamination and other causes, Leonard and her team were left with swabs from 143 surfers and 130 non-surfers.
