How shark skin resists infection
For the study, an international team led by researchers at KAUST's Red Sea Research Center collected a total of 88 mucus samples from the back and gill skins with lesions as well as from healthy skins of 44 wild-caught blacktip reef sharks caught in the wild around the Seychelles Islands.
Researchers sequenced the samples to identify the bacteria present in them, then compared the samples from the different sharks and tested them to detect changes in response to injuries.
