(MENAFN- Gulf Times) Surfers and body-boarders were three times more likely to have potentially dangerous antibiotic-resistant bacteria in their guts than non-surfers, new research from the UK shows.
The findings highlight the omnipresence of superbugs and the peril they might pose even for healthy people participating in water sports, said lead author Anne Leonard, a research fellow at the European Centre for Environment and Human Health at the University of Exeter Medical School in Truro, England.
'When people think of superbugs and antibiotic resistant-bacteria, they think of the hospital, she said in a Skype interview. 'But there's evidence that new resistant genes could be evolving in the environment and getting into people.
'Protecting our environment will have a multitude of benefits, she said.
Drug-resistant infections could kill 10 million people every year starting in 2050, a previous study estimated.
Because surfers swallow more seawater than other swimmers, Leonard expected to find more antibiotic-resistant bacteria in their guts. But, she said, the study found more than she expected.
Researchers analysed faecal samples collected in 2015 from 273 volunteers, including 143 who were frequent surfers or body-boarders in UK waters.
Surfers and body-boarders had triple the rate of E. coli resistant to the antibiotic cefotaxime in their faecal samples. Thirteen surfers, compared to four non-surfers, carried bacteria that would continue to grow even if treated with cefotaxime, one of the few antibiotics used to treat serious infections.
Surfers and body-boarders also were four times more likely than non-surfers to have in their bellies E. coli containing a mobile gene that makes bacteria resistant to antibiotics. The gene can pass between bacteria and spread the ability to resist antibiotic treatment.
People likely to have been exposed to antibiotic-resistant bacteria in other environments were excluded from the current study. But because participants were not screened for the presence of antibiotic-resistant bacteria before surfing, researchers cannot positively attribute the presence of bacteria to the coastal waters.
Antibiotic-resistant E. coli can be harmless, and it is possible that the bacteria might be gone from the surfers' guts in a matter of months, Leonard said. But antibiotic-resistant bacteria can lead to gastrointestinal symptoms, urinary-tract infections and meningitis.
The United Nations Environment Assembly recently recognised the spread of antibiotic resistance in the environment as one of the world's greatest emerging environmental concerns.
Nevertheless, the study's findings need not prompt surfers to quit, Leonard said. Surfers concerned about their exposure to antibiotic-resistant bacteria in the ocean can try to check the water quality before swimming and may want to avoid surfing after heavy rain, when sewage and manure fertiliser is more likely to wash into the sea, she said.
