When bacteria change, antibiotics can stop working.
Antibiotic resistance is a major and growing global health threat. These five recent examples show us how dangerous it can be.
Antibiotic resistance is not new but recent developments increase the urgency for action.
Superbugs used to pose the greatest risk to people with compromised immune systems and those who had surgery. But their sexual transmission means antibiotic resistance can spread much more widely.

A team of medievalists and scientists look back to history – including a 1,000-year-old eyesalve recipe – for clues to new antibiotics.

Quantum dots - minuscule semiconductor particles with specific light-absorption properties - can kill drug-resistant superbugs without harming the surrounding healthy tissue.
While many of the fruits of the human genome project could be decades away, DNA sequencing of drug-resistant bacteria has been striding forwards
Antibiotic-resistant bacteria are a leading cause of hospital infections.
New research shows the best way to treat hospital infections caused by C. difficile may be with more of the bacteria.
Staph aureus bloodstream infection has a 12-month death rate of between 20 and 35%.
Which of the following conditions would you prefer to have during your next stay in hospital? A. Staphylococcus aureus (Golden Staph) bloodstream infection; or B. a heart attack?
A superbug commonly found in medical facilities in Iraq and Afghanistan produces a resistance protein that renders hospital…
Whole genome sequencing can help identify the source of the antibiotic resistance.
Some recent headlines from Australian newspapers: NSW hospitals worst place for Golden Staph; CA-MRSA - the killer in our midst; Superbug onslaught. By now, most people are aware that antibiotic-resistant…
