Scientists warn about the threat that is on the skin of each person and can cause death
Scientists from the University of Bath have warned that bacteria living on the skin of every human, mutate to protect themselves from drugs, can cause infection after the surgery.
According to doctors, these bacteria are similar to MRSA — Staphylococcus aureus that is resistant to antibiotics. During the tests, the researchers found the most deadly forms of bacteria that were found on the skin of people infected after the surgery.
So, the bacteria Staphylococcus epidermis that live on the skin of each person and are normally harmless, can fall into the wound after the operation and cause serious deadly infections. Experts warn that doctors should treat these bacteria more seriously and to identify the most vulnerable people.
Determine if patients have a deadly variants of bacteria can help to prevent or quickly treat a postoperative infection. In their study, researchers found more than 60 differences between genes of bacteria on the skin of patients infected after surgery, and between genes of bacteria on the skin of healthy patients. Changes genes make bacteria such as Staphylococcus epidermis, more prone to cause life-threatening disease and can be identified in examining smears of the skin.
More deadly strains of bacteria have properties that allow them to easily spread through the bloodstream and suppress the immune system, so they can cause a fatal disease, experts say. Altered genes also make the cell surface of bacteria are sticky and help them to form a protective film that makes them resistant to antibiotics.
“Because bacteria are numerous enough, they can multiply very quickly, changing the genes to each other, says Professor Sam Sheppard. — If we do nothing to control it, there is a risk that bacterial genes will continue to mutate, in connection with post-op infections resistant to antibiotics, may become even more common”.
Recall that the scientists said about the threat that lurks everywhere: “He’s alive”
