The population of bacteria in your pores and skin changes if you swim in the ocean, probably growing your danger of an infection, researchers report.
They collected samples of pores and skin bacteria from the legs of nine individuals before they took a 10-minute swim within the ocean, after that they had air-dried utterly following their dip, after which six and 24 hours after their swim.
Before swimming, all of the individuals had completely different communities of pores and skin micro organism, or pores and skin microbiome, from each other. 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.
Six hours after swimming, the members’ pores and skin microbiomes had began to return to their pre-swim state, and had been far alongside in that course of 24 hours later, in accordance with the analysis to be offered on the annual assembly of the American Society for Microbiology, in San Francisco.
The examine was prompted by earlier analysis displaying a hyperlink between ocean swimming and infections and by excessive charges of poor water high quality at many seashores, which might result in pores and skin infections, ear infections and gastrointestinal and respiratory sickness.
The Vibrio genus consists of the bacterium that causes cholera. Six hours after swimming, Vibrio had been nonetheless current on a lot of the members, however 24 hours after swimming, solely one participant had them.
The fraction of Vibrio species detected on the swimmers’ pores and skin was greater than ten occasions larger than the fraction in ocean water, suggesting Vibrio has a particular affinity for attachment to human pores and skin, in keeping with the researchers.
They noted that pores and skin is the body’s first line of protection in opposition to contaminated water.
