The overuse of antibiotics puts vulnerable patients and society at risk.
Drug-resistant strains of gonorrhoea, once easily dispatched with penicillin, are spreading across the globe resulting in chronic pain and sterility.

Here are highlights from The Conversation US’ coverage of antibiotics and how scientists are trying to combat resistant bacteria.

Quantum dots - minuscule semiconductor particles with specific light-absorption properties - can kill drug-resistant superbugs without harming the surrounding healthy tissue.
Doctors and patients are aware of the problem – they just don’t see themselves as responsible for it.

Two of the most common antibiotic-resistant bacteria circulating in hospitals can be wiped out by transplanting faeces from a healthy animal into the gut of an infected one, a study on mice has found.
We used to think that antibiotic resistance came at a cost for bacteria, making them weaker. It turns out that for some bacteria, resistance can make them stronger and more virulent.
New antibiotics are desperately needed to treat these infections.

The fight against antibiotic-resistant bacteria – so-called “superbugs” – is a huge challenge, one that the World Health Organization has described as a grave global problem. When superbugs hit the headlines…
Bacteria-eating viruses that kill the hospital superbug C. difficile have been isolated by scientists. The use of these kinds of viruses, known as phages, to tackle bacterial infection was employed before…
Infections and deaths caused by superbugs are increasing every year. So the government’s five-year strategy to tackle the problem, if a little tardy, is a welcome step. In January, Chief Medical Officer…
A new antibiotic that is effective at killing anthrax and superbug MRSA bacteria could be a weapon in the fight against antibiotic resistance - and terrorism. Anthracimycin, a chemical compound derived…
A microscopic version of this kills bacteria.

The use of silver in medicine is as old as western medicine itself. Hippocrates is known to have used it to treat ulcers and wounds, the Romans almost certainly knew of its healing properties, its use…
The drugs don’t work. But a swifter way of identifying bacteria could reduce the need for antibiotics.

Researchers have taken the first step towards designing a rapid way of identifying harmful bacteria in infections, demonstrating the potential for faster patient treatment and decreased reliance on antibiotics…
Unregulated antibiotic use in many Asian farms can lead to widespread resistance, which is passed to humans through the food chain.

Experts have warned of the growing risk of travellers to India, China and South East Asia bringing home E.coli infections that are immune to treatment with a normal course of antibiotic tablets. People…
Widespread and unmonitored use of antibiotics in commercial Chinese pig farms may pose a risk to human health worldwide, the study said.

Unchecked use of antibiotics in Chinese farms had led to widespread antibiotic resistance, a new study has found, with researchers warning the problem may spread worldwide through manure and fertiliser…
There are no magic bullets in the antibiotic pipeline that will eradicate the superbugs.

Bacteria are one of the most successful colonisers of the planet. They can be found in almost all environments we know – from the deepest oceans to acid lakes, and inside and on our bodies. And the history…
