Ocean Bacteria Alters Skin Microbiome After Just 10 Minutes Of Swimming


'While many Vibrio are not pathogenic, the fact that we recovered them on the skin after swimming demonstrates that pathogenic Vibrio species could potentially persist on the skin after swimming, ' said Marisa Chattman Nielsen, a PhD student at the University of California.

So be sure to shower after swimming in the ocean, and try not to get any seawater in your mouth. The research team employed nine volunteers who met the criteria of no sunscreen, occassional exposure to the ocean, no bathing with the next 12-hours and no antibiotics for six months. The skin's gut microbiomes that live on the surface of our skin plays an important role in these defense measures. However, after swimming, all of them had related communities on their pores and skin, which had been fully totally different from their earlier than-swim communities, the research confirmed. But what researchers were really surprised by was the concentration of the bacteria - particularly Vibrio bacteria - that was found on the skin vs.in the water after just 10 minutes of swimming.

Dermal tests proved that all the participants who swam in the ocean featured traces of ocean bacteria, even if 24 hours had passed. And the exposure to these harmful bacteria can cause skin infection, ear infection, stomach problems, and so on.

The results were quite impressive as the individuals featured a similar community on their skin after the swimming, in comparison to different communities at the start of the test.

This research has been conducted due to other previous studies which have been showing various associations between ocean swimming and infections.

A new study elaborated by researchers from the University of California claims that exposure to the oceanic water can affect the microbiome of the human skin negatively, by altering its structure and composition.

Nielsen and her team, according to PHYS ORG, detected ocean bacteria on all participants after air drying. Nielsen. The Vibrio genus includes the bacterium that causes cholera.

The researchers detected Vibrio species on the subjects' skin.

Before the participants entered the water, researchers swabbed the participants on the back of the calf.

All the participants in the ocean swimming experiment showed ocean bacteria symptoms after air drying at six and 24 hours after swimming in the ocean. The fraction of Vibrio species detected on human skin was more than 10 times greater than the fraction in the ocean water sample, suggesting a specific affinity for attachment to human skin.

'A healthy microbiome protects the host from colonization and infection by opportunistic and pathogenic microbes'.

For the study presented at the annual meeting of the American Society for Microbiology, researchers focused on a group of selected beach goers.
