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.
John Gerrard says a developed city like Sydney could not cope with an epidemic of the scale of the recent Ebola outbreak.

Promising scientific consensus is a perilous principle on which to found meaningful engagement between experts and the public.
To finish, or not to finish, your course of antibiotics? There’s little doubt that you shouldn’t stop midstream.
New reports that stopping antibiotics when you feel better is better for you could do more harm than good. But it has reopened the debate on how long antibiotics should be used.
Green colonies of allergenic fungus Penicillium from air spores on a petri dish. Penicillin was the first antibiotic.
We've been told for a long time that we must take all of our antibiotics. But maybe we didn’t need so many to begin with. Here's why.
An article in a leading health journal causes confusion and undoes years of hard work in raising awareness of antibiotic resistance.
We’re increasingly seeing bugs in Australia resistant to many antibiotics. We’re yet to see one resistant to ALL antibiotics.
In the last decade we've seen a ten-fold increase in the number of bacteria resistant to last-resort antibiotics.
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.
An epidemic of Group B meningococcal disease in New Zealand prompted the development of a vaccine, which also provides moderate protection against gonorrhoea.
As the WHO calls for urgency to address antibiotic resistance in gonorrhoea, new research shows that a vaccine developed against an unrelated disease offers protection.
Modern diets are changing the compositions of our gut microbiota, and with that, our personalities.
For most of the twentieth century, we were at war with microbes, leading to substantial changes in our body's ecosystem. This has changed our diets, disease profile, moods and even personalities.
Young people are disproportionately affected by sexually transmitted infections, but they face several barriers to getting tested.
Despite significant medical advances, rates of sexually transmitted infections are on the rise, including some old foes like syphilis.
