Scientists warn that bacteria living on the skin of all human beings are turning to defend against antibiotics and medications, and can lead to an increase in postoperative infections. Bacteria resemble hospital germs (MRSA), already resistant to antibiotics.
Staphylococcus (usually harmless) lives on everybody's skin, but can reach wounds after surgery, causing serious infections.
Scientists at the University of Bath have identified other deadly forms of bacteria found on the skin of infected people after surgery. They say knowing which patients carry the most lethal type can help doctors prevent or treat infections after surgery.
As new bacteria constantly enter the skin, highly drug-resistant strains can spread easily.
"Staphylococcus aureus kills people's eyes and has been clinically ignored because it is often assumed to be contaminated with laboratory specimens or simply accepted as a known surgical risk," said Professor Sam Shepard of the Milner Center for Development. Injuries after surgery can be very serious and fatal.
Scientists have discovered 61 differences between bacterial genes found on the skin of infected patients after hip or knee replacement surgery or bone stabilization, and in healthy patients.
The deadly bacterial strains have proven to be better equipped to spread in the bloodstream and avoid the immune system, which means that they can cause a deadly disease. The mutating genes make the surfaces of bacterial cells sticky, allowing them to form a protective layer, making them resistant to antibiotics.
