The sharks have only a few predators in the ocean, but a new study has shown that they are resistant to the infection due to the bacteria.
Infection-drug-resistant microbes, which is related to blacktip reef sharks have allowed them to suffer the wounds, but it does not show signs of infection, according to the researchers, it is providing a “first step towards the understanding of this phenomenon,” according to a statement accompanying the survey.
“We were surprised to see me, and not in the finding of a substantial change in the skin’s bacterial communities,” said the study’s lead author, Claudia Pogoreutz, in a statement.

“This suggests the shark’s skin doesn’t get infected easily, and that the indigenous bacterial community of the skin can be maintained, even after the injury,” Pogoreutz added to it. “I think We really need to look at the bacterial and functions of innate immunity and the opportunity to understand what is really going on and how the healing of the wound, at them is permitted.”
Pogoreutz, and other researchers are looking at phlegm samples of the injured and the uninjured of sharks in the Seychelles Islands with the help of the DNA sequencing of the core skin microbiome” has been associated with the genre.

There were differences detected in sharks, in various locations, Pogoreutz further, pointing out it could be a number of factors.
“The differences in the area of shark skin, the microbial communities may be a reflection of differences in the environment, such as temperature, population density, availability of nutrients and / or contaminants, however, we cannot rule out the possibility that the change may provide an adaptive advantage for them,” Pogoreutz he said. “There is still so much to learn with regards to the shark skin-associated bacteria.”

The study, which was published in the scientific journal Animal Microbiome.
According to the Florida Museum of Natural History in new york, blacktip reef sharks are ‘not a major threat to human well-being” and “to be in abundance on the coral reefs, which makes them a popular species in the reef and dive tourism.”
There have only been 11 recorded accounts of the blacktip reef shark will bite humans, since 1959, the museum said, citing data from the International Shark Attack File.
According to the International Union for the Conservation of Nature, blacktip reef sharks are considered near Threatened by the species that are susceptible to the negative effects of the fishing industry and the destruction of their natural habitat.
