Study: Every person has life-threatening bacteria on his skin



A team of researchers at the University of Bath (United Kingdom), led by Professor Sam Sheppard, warned of the danger of a potentially fatal bacterium, which is so abundant that it is in the skin of all the people in the world.

In their study, the team identified a set of 61 genes that allow this bacterium called Staphylococcus epidermidis – usually innocent – to cause living threatening diseases, according to the Scientific Total portal. According to the researchers, these genes cause the bacteria to evolve in the blood flow, prevent the immune response of the body, and make the cellular surface fixed so that these bacteria can form a biophil there and thus be immune to antibiotics.

It states that it is a close relative of the bacterium MRSA (Staphylococcus aureus, immune to methicillin), which can cause diseases as important as sepsis or pneumonia. Researchers warn that Staphylococcus epidermidis is an important cause of life-threatening infections after surgery, but is often predicted by doctors due to its abundance.

According to Sam Sheppard, the bacteria "It has always been clinically ignored because it often assumed to be contamination in laboratory samples, or simply accepted as a known risk of surgeries. "However, he added that because of their abundance, these bacteria" can evolve very quickly by exchange of genes to each other ".

"If we do nothing to control this, there is a risk that these diseases causing diseases spread more widely, which means that postoperative infections – which are resistant to antibiotics – could be even more common," he concluded.
