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.
Doctors and patients
Antimicrobial resistance continues to be a growing concern for our future health. Whose responsibility is it to intervene?
It’s bacterial biofilms that give the Grand Prismatic Spring its colorful hues.
The vast majority of the bacteria that surround us are not free-floating but prefer to band together in cooperative communities called biofilms. How do biofilms form and cooperate?
Bloodletting was treatment for infection in the past.

While some ancient therapies proved effective enough that they are still used in some form today, on the whole they just aren't as good as modern antimicrobials at treating infections.
The more we take antibiotics, the more likely we are to have superbugs down the line.
Antibiotics can prevent serious harm and stop infections becoming fatal. But they won't kill common cold and flu viruses, and careless overprescribing by doctors can do more harm than good.
New Delhi’s Yamuna River, like much of India’s water, is polluted. The world urgently needs low-carbon ways to clean things up.
Much of the world still lacks access to proper sanitation and clean water - an issue that needs urgent action. But without low-carbon technologies, clean water could come at the expense of the climate.
Like something straight out of a biofilm.

Biofilms have developed to let nutrients in but keep antimicrobials out.

We spend much of our time inside buildings. What chemicals and microbes are in here with us? And how do they affect each other? One scientist collects dust to find out.
