4-Sep-2018: Staphylococcus epidermidis, a superbug resistant to all known antibiotics is spreading in hospitals.

A superbug resistant to all known antibiotics that can cause “severe” infections or even death is spreading undetected through hospital wards across the world. Researchers at the University of Melbourne discovered three variants of the multidrug-resistant bug in samples from 10 countries, including strains in Europe that cannot be reliably tamed by any drug currently on the market.

The bacteria, known as Staphylococcus epidermidis, is related to the better-known and more deadly MRSA. It’s found naturally on human skin and most commonly infects the elderly or patients who have had prosthetic materials implanted, such as catheters and joint replacements.

Some strains of the bug made a small change in its DNA that led to resistance to two of the most common antibiotics, often administered in tandem to treat hospital infections. These two antibiotics are unrelated and you would not expect one mutation to cause both antibiotics to fail.

Many of the most powerful antibiotics are extremely expensive and even toxic, and the team behind the study said that the practice of using multiple drugs at once to prevent resistance may not be working.

Scientists say that the superbug resistant to all known antibiotics can cause "severe" infections or even death is spreading undetected through hospital wards across the world. The researchers said they believe the superbug is spreading rapidly due to the particularly high use of antibiotics in intensive care units, where patients are sickest and strong drugs are prescribed as routine.

The World Health Organization has long warned of antibiotic overuse sparking new strains of killer, drug-resistant bacteria. Another Australian study, published last month, suggested some hospital superbugs are growing increasingly tolerant to alcohol-based disinfectants found in handwashes and sanitizers used on hospital wards.
