There already exist some promising new antibiotic therapies, and more are in the pipeline. However, our economic model prevents researchers from moving them out onto the market.
The end of effective antibiotics will be frightening. Life expectancy will fall dramatically and people of all ages will die from illnesses that we are used to treating with $10 worth of pills.
Hand washing is an effective way to help prevent the spread of bacteria.
Millions of bacteria live on our skin without making us sick. It's when they manage to get through that they can be dangerous – particularly if they're resistant to antibiotics.

Smooth surfaces often provide nooks and crannies for bacteria to hold onto and create a colony. New research with nanoparticles is revealing the secrets of surfaces that prevent bacterial attachment.
Our view of this essential dimension of earth’s biome has been shaped by the manufacturers of cleaning products.
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.

It's not a matter of if, but when, the next deadly pandemic will strike. Will the world be ready?
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.

Triclosan, an ingredient in soap and many household cleansers, has gained a bad reputation. A recent study looking for a way to boost an antibiotic, however, found that tricloscan did a great job.

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.
Bacteria exchange genes easily, but a newly discovered set of rules that regulate these exchanges could help us to prevent the spread of antibiotic resistance.
The discovery of molecular rules that regulate the transfer of genetic material between bacteria could help prevent the spread of antibiotic resistance.
Cattle that are grass-fed, antibiotic- and growth hormone-free gather at a farm in Oregon in 2015. There’s a debate over whether antibiotic use in livestock makes germs more resistant to the drugs, and results in infections being passed on to humans who consume the meat.

The use of antibiotics in raising livestock is complex. We could be moving towards a less-than-ideal result due to poor understanding, over-simplistic messaging and a rush for competitive advantage.
Bacteria in the dish on the left are sensitive to antibiotics in the paper discs. The ones on the right are resistant to four of the seven antibiotics.

Antibiotic-munching microbes may prove useful for mopping up contaminated water supplies and land.
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.

New research shows just 1% of E. coli bacteria's genetic mutations are lethal.
High-tech ways to scan nature’s own creations.
Pharmaceutical companies focus on small molecules they've devised – and can easily patent. But nature's already come up with many antibacterial compounds that drug designers could use to make medicines.
A giant ant carries a dead fellow in the name of cleanliness.
Ants produce their own antimicrobial chemicals to fight bacteria.
Pills and ills.
Antimicrobial stewardship is proving effective, but we're not fully across what is happening.
Researchers are using epigenetics to find ways to 'turn off' bacteria's ability to cause infections.
New Zealand researchers have found that the active ingredients in commonly-used weed killers like Round-up and Kamba can cause bacteria to become less susceptible to antibiotics.
Improper use of antibiotics is one reason for the rise in antibiotic resistance, but new research shows that ingredients in common weed killers can also cause bacteria to become less susceptible.
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.
