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.
The truth about cats and dogs.
Farm animals are the subject of WHO initiatives around antibiotics, but domestic pets could actually be a bigger risk.
Clostridium difficile bacteria causes diarrhea and inflammation of the colon.

A new type of antibiotic uses DNA to fight a common deadly microbe, Clostridium difficile. These new drugs are inexpensive and adaptable and can be modified to target any bacterium, lowering the chance of drug resistance.
Research shows potential for delivering our drugs in ways that would make it harder for antibiotic resistance to evolve and spread. Here we see a close up view of a biofilm of antibiotic-resistant bacteria.
As a post-antibiotic future beckons, how can humanity protect itself against the proliferation of superbugs? Research suggests 'drug sanctuaries' in hospitals could be a promising solution.
A giant ant carries a dead fellow in the name of cleanliness.
Ants produce their own antimicrobial chemicals to fight bacteria.
Researchers are using epigenetics to find ways to 'turn off' bacteria's ability to cause infections.
Bacteria don't just mutate to beat antibiotics, they also make changes on the fly.
Some patients may be prescribed antibiotics as preventatives, rather than to treat infections.
We know overuse and inappropriate use of antibiotics contribute to resistance, so it's important we develop strategies to improve practice.
Our study suggests setting targets for antibiotic prescribing is the next step to curb their overuse.
A study that shows GPs are prescribing about five million too many antibiotic scripts a year means we have to take a radical new approach to reducing use of these drugs.
Aspergillus fungal culture.
When it comes to fighting antimicrobial resistance, most of the focus is on bacteria. But we'd be foolish to forget about fungi.
Antibiotics are administered to surgery patients to prevent infections.
Infection of wounds for surgery patients is on the rise in developing countries. A shorter dose of antibiotics is appropriate.
Many in the Western Front contracted haemorrhagic dysentery.

When commemorating our troops, doctors and nurses this Anzac Day, consider also tipping your hat to the discovery of bacteriophages. In the post-antibiotic era, our health might just depend on them.
Estuaries are natural filtering points between freshwater and the ocean where pollutants tend to accumulate.
Unless we do something about about antibiotic pollution in the world's waterways, the next trip you take to the coast for a seafood dinner just might be your last.
People mainly think of GPs over-prescribing antibiotics, but ubiquitous use in farming and other areas also contributes to resistance in bacteria.
We need a concentrated and coordinated effort by government and scientists if we're to stave off the threat of antimicrobial resistant bacteria.
According to the World Health Organisation, antimicrobial resistance is now at crisis point.
The US Centers for Disease Control has reported a woman in her 70s has died of overwhelming sepsis caused by a bacterium that was resistant to all available antibiotics.
Antibiotic use is a big issue as the more we use, the more likely bugs are to grow resistant, rendering them useless.

Health minister Sussan Ley said Australia’s use of antibiotics in general practice is 20% above the OECD average. Is that right?
Tackling antimicrobial resistance relies on us tackling the interrelated areas of human, animal and environmental health.
The federal government is tackling antimicrobial resistance with a 'One Health' approach. But what is One Health and what can it offer that other approaches haven't?
Why US$790m is not enough to win the war against antibiotic resistance.
Many antibiotics simply no longer work.
There's one important piece of the puzzle we're missing when it comes to antimicrobial resistance.
Scientists are excited they’ve found potential new antibiotics – in us.
Alexander Fleming discovered penicillin in 1928 and revolutionised the treatment of bacterial infections. Ever since then we have been searching for new antibiotics.
